Hawaii Prepares for Possible Tsunami¹

Scientists say rising temperatures on Earth’s surface are to blame for rising sea levels. The reality of rising sea levels means many coastal² and island communities are at risk when a tsunami strikes. The island state of Hawaii is taking steps to prepare for tsunami waves. Officials there want to be ready if such an event takes place.

In 2011, a strong earthquake struck northeastern Japan. The quake caused a tsunami. The huge waves damaged several nuclear reactors³ in the area. Those events led Hawaiian officials to reconsider their plan of action for dealing⁴ with a tsunami.

Scientists and emergency officials in the state are now preparing for an extreme tsunami -- the kind that comes every 500 to 1,000 years.

Almost 19,000 people died when the earthquake and tsunami struck Japan four years ago. Scientists say the Hawaiian Islands may be just as helpless if such a disaster were to take place there.

Rhett Butler is a researcher at the University of Hawaii. He says a mysterious hole on the island of Kauai has evidence that a huge tsunami hit Hawaii 500 years ago. David Burney discovered the evidence. He found remains⁵ of old shells, coral and other sea creatures in a cave about 100 meters from the ocean.

Civil defense⁶ agencies keep people prepared by testing their tsunami warning system.

Scientists say a major tsunami could happen again. They warn that if a powerful earthquake struck the Aleutian Islands in the northern Pacific, a super tsunami could follow.

A researcher at the University of Hawaii created a computer model to show what would happen if an earthquake struck the Aleutians and produced a tsunami. The model showed the waves from a major quake could move further inland across Hawaii than officials thought, deep into areas considered safe.

The Hawaii Emergency Management Agency works with local governments to create disaster plans. Kevin Richards is an emergency planner with the agency. He says before the computer model, Hawaiian officials thought they would only have to evacuate⁷ 85,000 people from the island of Oahu.

“If this event took place, we’d have to move 340 and 350,000 people to safety -- a much more daunting⁸ task. And safety is not in the same place any more. It’s much further away, it’s further up the hill -- it’s further inland.”

Some Hawaiians could drive to higher ground. But driving is not possible in some parts of Hawaii. So people would have to walk to safety or go to the fourth floor or higher of a reinforced concrete building.

Officials are now developing a new plan of action, with an extended evacuation zone for an extreme tsunami. Scientist Rhett Butler says because of what happened in Japan in 2011, people take the threat seriously.

“It doesn’t mean it’s gonna happen in our time. It doesn’t mean it’s gonna happen this year or next year. But it’s just the nature of the tectonic forces on our planet. They just keep marchin(g) along, and once you relieve all these stresses with these truly great earthquakes, the water responds.”
