Timeline for a tsunami at Hilo Medical Center


By Elena Cabatu | Special to Hawaii 24/7

Hilo Medical Center

Hilo Medical Center was ready for the Feb. 27 tsunami event. Upon receiving notice about the approaching tsunami, Hilo Medical Center sprung into action.

The following outline details how the hospital prepared for the tsunami:

2:30 am: Department of Health Hawaii District Health Office contacted Tracy Aruga, HMC Environmental Safety Officer/HAH’s (Healthcare Association of Hawaii) Area Coordinator. He reported to the Hawaii County Civil Defense Emergency Operations Center for a briefing on the situation.

4 am: HMC Environmental Safety Officer/HAH’s HI Island Area Coordinator briefed Reggie Agliam, HMC House Supervisor, of tsunami event. He also briefed the other East and West Hawaii health care facilities.

4:18 am: HMC Environmental Safety Officer/HAH’s HI Island Area Coordinator connected to hospitals statewide including HMC via HAH’s Web Emergency Operations Center (WebEOC).

5 am: HMC Environmental Safety Officer/HAH’s HI Island Area Coordinator briefed Arthur Sampaga, HMC Emergency Management Coordinator, of tsunami event.

5:45 am: HMC’s Hospital Command Center (HCC) opened and manned by HMC Emergency Management Coordinator.

6 am: HMC assessed for staffing, logistical resources, and status of campus utilities such as fuel levels for emergency generators and medical gas/oxygen inventories; created a list of possible patient discharges to anticipate incoming tsunami casualties; and researched if there were any HMC home-care patients who lived in evacuation zone (none identified).

6:30 am: On-call administrator, Dan Brinkman, Regional Chief Nurse Executive, assumed leadership role of Incident Commander for the Hospital Command Center.

6:45 am: Hospital Command Center staffed with Command Chiefs and Section Leaders.

7 am: HMC participated in HAH statewide conference call. Incident Action Plan developed for the first 4 operational hours.

8 am: All department heads and charge shift personnel briefed at Command Center.

9 am: HMC’s Residency and Pediatrics Clinics on Mohouli Street secured in tsunami zone.

10 am: HMC participated in conference call with HAH for a statewide update on situational status. IAP updated.

10:30 am: Complete assessment of up coming shifts and patient census performed in anticipation of prolonged event.

10:30 am-2:30 pm: HMC stood ready for approaching tsunami and its after effects.

2 pm: All clear given for tsunami threat. HMC Incident Commander terminated HCC operations.

“Hilo Medical Center has an effective process and plan for responding to emergency situations like the recent tsunami event,” said Howard N. Ainsley, East Hawaii Regional CEO of Hawaii Health Systems Corporation. “It was very evident that our staff dedicates countless hours of training to ready the hospital on a moment’s notice.”

Among many precautions involved in preparing the hospital, emergency personnel had to assess the facility’s capacity and ability to care for and feed patients.

The Maintenance Department checked and prepared emergency infrastructure to keep services going in the event a power outage would have occurred.

The Pharmacy Department reported its supply of medication.

The Operating Room rearranged the operating schedule.

In addition, physicians were available to assure care.

Departments that reported to the Hospital Command Center include: Nursing, Emergency, Imaging, Patient Services, Human Resources, Maintenance, Housekeeping, Bio-Medical, Dietary, Pharmacy, and Security.

“Our community and its hospital are in the hands of capable and well practiced team of emergency responders,” said Dr. Robert Irvine, Chair of the East Hawaii Regional Board. “Preparing a hospital as large as ours is an enormous feat. I thank everyone involved.”

Volcano Watch: Golden anniversary of Chilean quake comes early

(Volcano Watch is a weekly article written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.)

May 22, 2010, marks the 50th anniversary of the 1960 magnitude-9.5 Chilean earthquake, which was the largest earthquake worldwide in the last 200 years or more. But, for Hawaii residents, this great earthquake is rarely far from memory, due to the destructive tsunami it triggered, which killed 61 people in Hawaii and 122 in Japan.

An early reminder of this anniversary came in the form of a magnitude-8.8 earthquake that struck Chile in the early morning hours of Saturday, Feb. 27, 2010 (local Chilean time). Located approximately 230 km north of the 1960 earthquake, this event produced a modest tsunami that crossed the Pacific Ocean.

Luckily, in Hawaii, we experienced wave heights of only a few feet. However, in Japan, waves were high enough to flood several coastal towns.

Both the 1960 and the 2010 earthquakes occurred at the boundary between the Nazca and the South American tectonic plates. The two plates are converging at a rate of 70 mm (3 inches) per year as the Nazca plate is subducted beneath the South American plate. The relatively fast convergence is the reason why this region has a long history of large earthquakes and can expect to have more in the future.

From Chile, it takes about 15 hours for tsunami waves to reach Hawaii and about 22 hours to reach Japan. Thus, local authorities have ample time to warn residents and prepare for the approaching waves. If used wisely, this lead time allows for orderly evacuations of low-lying areas, as demonstrated by the smooth response to the Feb. 27 tsunami warning.

There was also ample time for evacuation in Hawaii on May 22, 1960, as the tsunami traveled across the Pacific Ocean. At 6:47 p.m., Hawaiian standard time, the U.S. Coast and Geodetic Survey issued an official warning that waves were expected to reach Hilo around midnight. At 8:30 p.m., coastal sirens in Hilo sounded and continued to sound intermittently for 20 minutes.

Many people heeded the warning and evacuated, but some did not, and when the first wave arrived just after midnight, hundreds of people were still at home on low ground in Hilo.

Because the first waves were only a few feet (1-2 m) high, many people returned to Hilo, thinking that the danger had passed. But the highest wave of the tsunami struck shortly after that, at 1:04 a.m. May 23.

Just before midnight May 22, 1960, Jerry Eaton, a seismologist at the U.S. Geological Survey’s Hawaiian Volcano Observatory, and four companions set up instruments in order to measure the tsunami wave heights from the Wailuku River Bridge on Hilo’s bay front.

Their measurements show that the tsunami was a series of waves that occurred over a span of more than two hours, with the highest wave of about 4.3 m (14 ft) arriving just after 1:00 a.m.

These wave heights sound modest compared to the 15-m (50 ft) waves that surfers tackle on the north shores of Hawaii. Tsunami waves, however, are much different, and more dangerous, in that each wave can raise sea level for tens of minutes and can push an incredible amount of debris-filled water on land.

Tsunami size is controlled by how much an earthquake displaces the sea floor. So, small differences in earthquake location (closer or farther from the coast) and earthquake depth can have big effects on whether or not a tsunami will be generated — and how big it will be.

Magnitude can also make a difference. The 1960 earthquake released more than 10 times more energy than the 2010 earthquake, which may have contributed to the size of the 1960 tsunami.

The Feb. 27, 2010, Chilean earthquake was well-recorded by scientists around the globe and will likely be studied for years to come. This should lead to a greater understanding of how these large earthquakes occur and under what conditions they produce widespread, destructive tsunamis.

Lingle praises state response to tsunami warning


Gov. Linda Lingle released this statement Tuesday, March 2:

When we received news Friday night of the devastating earthquake in Chile and the resulting tsunami waves that were approaching Hawaii, emergency response personnel across the state sprang into action. The outstanding coordination resulted in a well-executed operation to keep the residents and visitors of Hawaii safe.

State and County Civil Defense officials, scientists at the Pacific Tsunami Warning Center, lifeguards, police officers, firefighters and other first-responders were well prepared to carry out their duties, and they worked together calmly and efficiently.

Military leaders at Pacific Command on Oahu and officials from the U.S. Department of Homeland Security were standing by in case we needed their help. Hawaii tourism leaders worked closely with state and county officials to make sure our visitors were safe and well informed. The media ensured residents and visitors received accurate and timely information.

Our residents did their part by evacuating from danger zones and stocking up on emergency supplies – and they did so without panicking and without losing their aloha spirit.

Fortunately, the tsunami waves were much smaller than predicted and no damage was reported on any island. We were very fortunate.

Looking back at the events of this weekend, I come away with an even deeper appreciation of how extensively our state has prepared for emergencies, and how professionally everyone responded when the time for action arrived.

This gives me great confidence that our state will be ready for the next emergency, be it a tsunami, hurricane, earthquake or other natural or man-made disaster. At the same time, it is critical that we continue to prepare for emergencies and work to improve our response capabilities.

Mahalo to everyone who played a part in keeping Hawaii safe.

Tsunami: Monday morning quarterback talk

Karin Stanton | Hawaii 24/7 Contributing Editor

The tsunami sirens went off again at 11:45 a.m. Monday. The regular monthly test likely was more a source of comfort than an irritant to many on the Big Island.

Just two days earlier, the sirens blasted for a very different reason – a tsunami was coming, hammering across the Pacific Ocean at something like 500 mph following the 8.8M earthquake off Chile.

Scientists from the Pacific Tsunami Warning Center in Honolulu monitored their instruments and fed regular updates to authorities in Hawaii and dozens of countries around the Pacific Rim.

What arrived in Hawaii – and on many other shorelines – was not nearly as destructive as scientists warned it could be. Hilo Bay emptied and filled a handful of times, Maui reportedly had a surge of 3-5 feet and some piers were flooded in Japan.

By Monday, some residents were left wondering if the scientists, county and state might have over-reacted. Hawaii County officials however said they would make the same decisions again.

“We had every indication right from 9:30 p.m. Friday, right after the earthquake, that this could be serious,” Mayor Billy Kenoi said Monday morning. “With every report, there was no indication of a lessening impact.”

Kenoi signed an emergency declaration at 12:30 a.m. Saturday, as soon as the tsunami watch was issued for Hawaii.

“There are plenty of people and countries that wish they had scientists like we have, wish they had hours of warning. I make no apologies for committing every resource,” Kenoi said. “The county’s core service is public safety. Every dollar spent was a dollar well spent.”

Kenoi said the total county tab has not yet been determined, although he called for all county department chiefs to meet at 5:30 p.m. Monday for a debriefing.

In addition to discussing what worked, Kenoi said they will address what can be improved upon and run through what-if senarios.

“I’ve told my guys not to break their arms patting themselves on the back. We should use these lessons learned to improve and get better for next time,” he said.

“Nobody should be under any illusion that things will always turn out so well,” he said. “We were once again spared any devastation.”

Kenoi said he was very proud of how the county staff and crews reacted, and was pleased that residents and visitors took the warning seriously and made smart decisions to stay safe.

County Parks and Recreation director Bob Fitzgerald is a former football coach and still speaks like one.

“We had it game-planned from 8:45 p.m., but it’s not easy to call plays when you don’t know what’s coming,” he said. “We were ready for crunch time, but we never got called on it.”

Fitzgerald said the mayor has repeatedly drilled into his cabinet that they should be prepared for natural disasters and be ready to respond.

“As far as being prepared, it was a great response,” he said. “People felt very secure.”

Fitzgerald said his top topic going into Monday’s debriefing would be communications and ensuring there are multiple options for Hilo headquarters to stay in contact with each of the island’s districts.

Also on the agenda will be the county’s tsunami warning sirens. A handful of the sirens, which dot the shoreline areas around the island, did not go off Saturday morning.

At any given time, some sirens will need maintenance and repairs. That is why they are tested every month.

The county’s goal is to have every siren sound every time.

Visitor Industry

Big Island Visitors Bureau executive director George Applegate spent Saturday in the Civil Defense Emergency Operations Center in Hilo.

Keeping visitors informed and safe was the No. 1 priority, he said, and he was pleased with how county officials and hotel and resort staff handled people who might not be as prepared as residents.

Applegate said, he does not believe Saturday’s tsunami scare will have any long-term impact on the visitor industry.

Potential visitors watching the television coverage around the world will see that Hawaii is capable of protecting people and responding professionally and quickly to threats.

Visitors who experienced it are taking home a great vacation story, Applegate said, and will be sharing their adventure with family, friends and colleagues.

That their stories have a happy ending, Applegate said, is the the most important thing.

Tsunami: On the ground in Hilo

A Coast Guard C-130 aircraft orbits over Hilo during the tsunami warning.

Motorists rushed to gas pumps Saturday morning (Feb. 27) in Hilo to fill up and get out of town before roads were closed. Some gas stations had closed early, which meant the few stations left open had lines of vehicles snaked out of driveways onto the streets. People seemed patient, waited their turn and headed for higher ground.

The rest of downtown Hilo was empty with little to no traffic as the morning wore on. A couple bicycle riders peddled the wrong way down the center of Kilauea Avenue near KTA as they took advantage of the empty streets.

County crews from various departments including police, public works, parks and recreation manned intersections ready to shut them down with barricades and flags. Every intersection along Kalanianaole Avenue was manned by police.

So many officers that it was surprising to see just how many police are on the force when you call all of them and put them to work at the same time.

Spectators lined the top of a pick-up with planks to create a viewing deck for front row seats of the tsunami action.

Spectators started to jam into the Wainaku scenic lookout for an overview of Hilo Bay hours before the first wave was to hit. Police ended up clearing the crowd out of the parking lot as they made way for officers and fire crews to move in and out without dodging the puzzle pieces of parked cars earlier.

A few spectators relocated to the highway shoulder above the lookout to retain their front row seats on the tsunami. Others walked back down to the lookout near 11 a.m.

As the time reached 11:05 a.m, the projected time of the first tsunami strike, all eyes scanned Hilo Bay for any sign of a wave, receding water or other disturbances.

What they saw was a half-dozen helicopters buzzing over the bay, a Coast Guard C-130 aircraft flying overhead, a dozen or so sailboats in open water and a pair of humpback whales splashing around.

At 11:30 a.m. water started surging near the breakwater, churning up the brown bottom staining the blue ocean. The water in Hilo Bay appeard to be receding as people pointed to surface currents moving out of the bay.

Then everyone waited for a wave, a hint of a wave, a surge of water, but from the vantage point on the north end of Hilo Bay it was difficult to see much except a bouy that had moved out with the receding water was now moving in.

There were a few times when a surge could be seen far on the opposite side of the bay near the mouth of Wailoa River and another time as the water in the bay appeared to rise up touching the base of the point light at Wailuku River.

People appeared both relieved that there was no destruction, but also a little disappointed that they didn’t see much at all.

On the ground at the opposite side of Hilo Bay the close-up scene was a bit different. The energy of the ocean surge from the tsunami was funneled into Wailuku and Wailoa Rivers. Wailuku looked familiar with big choppy waves bouncing under the singing bridge upstream as it does anytime there’s big surf.

At Wailoa River, the water was pushing inland with standing waves coursing on the river in Wailoa State Park pulling mounds of grass and debris from the shoreline.

When the ocean waters receded thick mats of grass caught onto mooring bouys near the boat dock as large tree branches and other debris ran back and forth from the ocean to the park as the surges came in and out over and over again.

Debris float up and downstream in Wailoa River as the tsunami surge pushed in and out of Hilo Bay.

A boat near the dock strained at a line tied to a cleat as the vessel was pushed up river by the surge in and rose up as water washed over the dock, then it would lower with the water level and pull towards the ocean by receding waters. The river water continued to surge even after the all clear was given and the tsunami warning was cancelled.

People came down to the dock to watch the surge, take photos and videotape a fraction of what the power of the ocean can do.

Tsunami: ‘We’ve been very lucky for a very long time’


Inside the Emergency Operations Center of Hawaii County Civil Defense in Hilo Saturday morning. County department heads kept in contact with workers in the field during the tsunami warning. Photography by Baron Sekiya | Hawaii 24/7

Karin Stanton | Hawaii 24/7 Contributing Editor

By 9:30 p.m. Friday, Feb. 26, Hawaii County officials were gathered in the Civil Defense headquarters in Hilo, anxiously waiting for the next tsunami update.

Slightly more than 16 hours later, they were all still there, anxiously waiting to hear whether the danger truly had passed by Hawaii’s islands.

Director of Pacific Tsunami Warning Center Charles McCreery announced the good news, to cheers all around the room.

“We’re not seeing anything alarming,” McCreery said. “The wave was not any bigger than we expected. In fact, it might have been a little smaller. We’re all in agreement out here, we can end this thing for Hawaii.”

Mayor Billy Kenoi, who spent the night in the Emergency Operations Center, thanked the state and county leaders, workers, staffers and volunteers who leapt into action as soon as they heard the powerful earthquake had thundered under the ocean off Chile.

“I’m so proud of everybody,” Kenoi said. “Everybody kept their cool. The police, fire department, public works, parks, all our agencies did an incredible job. They conducted all their duties early and got it done to make sure no-one got injured or lost their property.”

The mayor also praised the Red Cross and Civil Air Patrol for their cooperation and readiness to assist.

“Some people might have a sense that this was a lot of time and effort and it wasn’t really worth it,” he said, “but it was worth every hour.”

Still, Kenoi said it was a tense night knowing that a tsunami was storming across the Pacific Ocean toward Hawaii for 10 hours.

“My stomach is still in knots. This was not a practice run,” he said. “We were prepared. You didn’t see anybody panic; you didn’t see anybody pointing fingers.”

At 12:30 a.m. Saturday, Feb. 27, when the state was put under a tsunami watch, Kenoi signed the emergency declaration that fully activated the Emergency Operations Center.

At that point, he said, officials decided to hold off on sounding the tsunami sirens. The first siren went off at 6 a.m., giving residents, hotel staff and business owners at least five hours for more than 20,000 residents and visitors to evacuate the island’s shorelines.

By 10:30 a.m., the police had locked down the inundation zones around the island and were vacating the area themselves. The areas are absolutely no-go zones, Kenoi said, to protect residents and to prevent looting.

“There were no reports of people not being cooperative,” he said. “For the most part, our island residents got prepared early and stayed off the streets, got to high ground and stayed with friends, family and relatives.”

Starting shortly after midnight and continuing into the dawn hour, residents shopped for essentials and cars queued up at gas stations.

All beach parks were closed and will remain closed through Sunday. Ditto for county transfer stations. Almost all scheduled events were cancelled or postponed.

The Department of Water Supply shut down water systems in Kapoho, Pohoili, Vacationland, Kalapana, Keaukaha, Downtown Hilo, Hilo Bayfront, Puako, Kawaihae, Alii Drive and South Point Road.

The emergency shut down was a preventative measure, aimed at protecting the entire county water system in the event it was compromised somewhere along the shoreline. Service was restored shortly after the all-clear.

Hilo International Airport also was closed. That was to facilitate evacuation of Keaukaha, an oceanfront subdivision that abuts the runway.

Boats and ships moved out of the island’s three harbors and into open water. Owners of two boats in Hilo Harbor were not found, and those boats remained in the harbor.

Across the island, 17 evacuation centers were opened, including 15 staffed by Parks Department workers and two staffed by the Department of Education. Had residents and hotel guests needed to be housed overnight, the Red Cross was ready to step in and convert the evacuation centers to shelters.

McDonald’s restaurants in Hilo and Kona donated hundreds of burgers to the county workers at the evacuation centers.

The county’s entire bus fleet was mobilized to ensure everyone had transportation.

County police, public works and parks crews have conducted several tsunami drills within the last year and reacted quickly and efficiently, Kenoi said.

“We’ve been very lucky for a very long time,” he said. “And I think we need to realize that we’re not always gonna be so lucky. You don’t want your first responders to get complacent at all.”

Of the county’s 72 tsunami sirens, four or five did not function which is not uncommon due to routine maintenance schedules.

“We feel very good about our preparedness,” Kenoi said. “We feel very fortunate that our residents know what to do and stay calm.”

In the end, Kenoi said, the county received no reports of injury or property damage.

Kenoi’s Flyover

A Blackhawk helicopter flies over Hilo with Mayor Billy Kenoi aboard.

Kenoi spent 90 minutes flying over Hilo’s shoreline and said he saw six or seven surges that sucked out 30 feet of coastline.

“We saw an incredible amount of surges,” he said. “We were on edge the whole time up there. You’re up there thinking ‘what’s coming?’ It’s the uncertainty.”

Kenoi said he was prepared to see the ocean sucked out, only to rush back into shore. However, he was alarmed to see the ocean pull out, exposing Coconut Island in Hilo Bay and emptying Wailoa River.

“We were thinking ‘Oh-oh, this is it,’” he said.

Eventually, the highest wave in Hilo was estimated at about 3 feet, although surges continued to roll in and out of the bay through the afternoon.

Kawaihae recorded only a slight increase and by the time the tsunami reached Kauai, it measured about one foot.

Statewide, the PTWC reported the highest wave at 3.2 feet at Kahului, Maui.

Ghost town

Meanwhile, streets and sidewalks all over Hilo were almost completely devoid of people. Businesses and restaurants were shuttered, roads barricaded and parks silent.

At Prince Kuhio Plaza, a handful of shops were open, although mall visitors – mostly hotels guests riding out the mandatory evacuation – gathered in the food court trading stories of the day and listening to radio updates.

McDonald’s manager Craig Okui said most people were taking it in stride.

“Something like this, it can’t be helped. Anytime it’s a tsunami, it’s serious,” he said. “It’s better to be safe than sorry, for sure. Nobody can outrun a wave.”

Okui said he was grateful the county was prepared.

“We have a very well-run Civil Defense department. I’m glad they are on our side,” he said. “All the preparation in the world does help if you can come out of something like this unscathed.”

What people had to say

Gov. Linda Lingle also signed an emergency proclamation for the state, until the tsunami watch was lifted.

“We were extremely fortunate and thank goodness our state came through this without any reported incidents,” Lingle said. “Our hearts go out to those who lost their lives and those injured in yesterday’s earthquake in Chile.”

Shortly after 8 a.m. at Mauna Kea State Park in the middle of the island, Frits Paerels, of New York City, and John Miller, of Ann Arbor, Mich., were studying a map of the Big Island.

The astronomers were on their way back from a business trip to Japan.

Their hotel on the Kohala Coast was evacuated, so they decided to do some site seeing.

“We’ve been watching it since about midnight,” Paerels said. “That’s the strange thing about disasters like this. You have plenty of warning, but it’s a creeping one. This could be huge, I think.”

Paerels said his wife was on her way from New York to join him.

“She’s due to arrive in Los Angeles in an hour. She’s going to be surprised,” he said. “She’s going to go ‘Oh, geez, I hope he’s smart enough to get up out of the way.’ But she knows I am.”

Further along Highway 190, just outside Hilo town, William Stockmaster Jr. and his sister Holly Kinney were parked on the shoulder.

They admitted they were worried about their grandfather and their family business, although their parents and children were safely inland.

“We’re just kind of contemplating how big it will be. They made it pretty clear that we’re in for something today,” Stockmaster said. “It’s exciting, but really scary too.”

Stockmaster works with his father at an appliance refurbishing company in the tsunami evacuation zone.

“That’s our bread and butter,” he said. “Everything is buttoned up as tight as it can be, but the ocean is really, really powerful and we just don’t know.”

Kinney said she was concerned for friends and family, but most worried about her grandfather, who refused to leave his sea-level property.

“He’s worried that people will get in there, so he won’t leave for nothing,” Stockmaster said.

The brother and sister had considered staying at her downtown apartment, but decided to head out of town to a spot where they could be safe and still see the ocean.

“It’s kind of scary,” Kinney said. “It’s not everyday you get to see something like this close up. Hopefully, not too close up.”

After the 2 p.m. press conference at the Emergency Operations Center, Mayor Billy Kenoi was headed home.

“I’m going to hug my kids and kiss my wife,” he said. “Then I’m going to take a long nap.”

Tsunami: Watch cancelled for Hawaii at 1:42 p.m.


Director of Pacific Tsunami Warning Center Charles McCreery ready to cancel watch for Hawaii.
“We’re not seeing anything alarming. The wave was not any bigger than we expected. In fact, it might have been a little smaller,” McCreery said. “We’re all in agreement out here, we can end this thing for Hawaii.”

Mayor Billy Kenoi, who spent 90 minutes in a helicopter flying over Hilo’s shoreline, said he saw six or seven surges that sucked out 30 feet of coastline.
“We saw an incredible amount of surges,” he said.

Kenoi said the county had received no reports of injury or property damage and remained “cautiously optimistic” that the major danger seems to have passed by the state.

“My stomach is still in knots. This was not a practice run,” he said. “Everybody kept their cool. The police, fire department, public works, parks, all our agencies did an incredible job. They conducted all their duties early and got it done to make sure no-one lost their lives or got injured or lost their property.”

Tsunami: Getting ready on the Big Island


The county’s 72 sirens began sounding the alert at 6 a.m., some five and one-half hours after Mayor Billy Kenoi signed an emergency declaration for the Big Island.

Tsunami were expected at 11:04 a.m. The mood remains calm in the county’s Civil Defense Agency headquarters in Hilo, as county officials watch six giant screens.

Hilo International Airport was closed to facilitate evacuation of an adjacent neighborhood, said mayor’s executive assistant Kevin Dayton.

Resorts, hotels, businesses and homes in the inundation zones were locked up tight several hours before the tsunami was expected.

About 30 minutes before the tsunami was expected, police and first responders moved away from shoreline areas, Dayton said.

All beaches were closed and all community events were cancelled, Dayton said.

Boats and ships moved out of the island’s three harbors and into open water. Owners of two boats in Hilo Harbor were not found, and those boats remain in the harbor.

County police, public works and parks crews have conducted several tsunami drills within the last year and reacted quickly and efficiently, Mayor Billy Kenoi said.

“We feel very good about our preparedness,” Kenoi said. “We feel fortunate our residents know what to do and stay calm. It’s important they follow instructions.”

Across the county, 17 evacuation centers were opened. In the event residents can not return to their homes, the Red Cross will be called in and the centers will be converted into shelters, Dayton said.

The Hawaii National Guard has generators and emergency equipment ready in case they are needed.

Kenoi went up on a National Guard helicopter just before the tsunami was expected, to survey any damage.

The Department of Water Supply cut water to roughly 5,000 customers within the tsunami zone as a preventative measure.

GOVERNOR LINGLE SIGNS

TSUNAMI EMERGENCY PROCLAMATION

HONOLULU – Governor Linda Lingle has signed an emergency disaster proclamation two hours before a tsunami generated by an 8.8 magnitude earthquake in Chile is expected to affect the State of Hawaii.
The proclamation, which includes the entire State, provides for the “expenditure of State monies as appropriated for the speedy and efficient protection and relief of the damages, loses and suffering resulting from the threatened disaster.”
Governor Lingle said signing the emergency disaster proclamation now will improve the State’s ability to respond quickly to any potential damage caused by the tsunami. Estimated first wave arrival time is 11:05 a.m. in Hilo. The tsunami is expected to affect all shores of all Hawaiian Islands and may last for several hours.
The disaster emergency relief period for the proclamation begins today, February 27, 2010, and continues until the Governor determines an appropriate time for termination.
