Tsunami waves hit Hawaii in the early morning hours Friday and were sweeping through the island chain after an earthquake in Japan sparked evacuations throughout the Pacific and as far as the western coast of the United States.
The Pacific Tsunami Warning Center says Kauai was the first island hit early Friday by the tsunami, and the waves surged in Waikiki. Officials predicted Hawaii would experience waves up to 6 feet (2 meters), and officials spent hours evacuating ahead of the storms. The waves early Friday weren't that large.
Waves have steadily risen over southern beaches on the island of Oahu. The initial waves in Hawaii appeared to have caused no damage.
Residents in coastal areas of Hawaii were evacuated to refuge areas at community centers and schools while tourists in Waikiki were moved to higher floors of their high-rise hotels.
Roadways and beaches were empty as the tsunamis struck the state, which had hours to prepare.
The tsunami was generated by an 8.9-magnitude earthquake in Japan.
The governor of Hawaii ordered the evacuation of coastal areas and warned residents to take the threat seriously. People waited in long lines stocking up on gas, bottled water, canned food and generators, and officials told residents to stock up on water and fill their cars with gas.
The tsunami slammed the eastern coast of Japan, sweeping away boats, cars, homes and people as widespread fires burned out of control.
"It's traveling at 500 mph - as fast as a jetliner - and likely won't change speed until it hits a large area of land," said Kanoa Koyanagi, a geophysicist for the Pacific Tsunami Warning Center.
French Polynesia also issued a tsunami alert Friday, and ordered coastal residents to higher ground. All schools have been closed throughout the French territory.
French Polynesia's high commission said the first high waves are expected to hit the Sous-le-Vent Islands at 6:50 a.m. local time Friday (1650 GMT), and then soon afterward hit Tahiti.
The highest waves, of up to three meters (about 10 feet), are expected to hit the Marquesas Islands. Authorities ordered residents there to seek refuge in sites at least 20 meters (66 feet) above sea level.
Waves are predicted to hit the western coast of the United States between 11 a.m. and 11:30 a.m. EST Friday. People near the beach and in low-lying coastal areas of Point Conception in Santa Barbara County were told to move immediately inland to higher ground.
While the tsunami is likely to go around smaller islands, the size of Hawaii's islands will amplify the waves, which will crash hardest against harbors and inlets.
"They're going to be coming in with high currents, they can pick up boulders from the sea floor ... they can pick up cars, they can pick up fuel tanks, those things become battering rams and so it just amplifies the destruction in a big tsunami," said Chip McCreery, director for the Pacific Tsunami Warning Center.
Waves almost 5 feet high hit Midway, a tiny island in the North Pacific about 1,300 miles (2,100 kilometers) northwest of Honolulu.
"We're preparing for the worst and we're praying for the best," said John Cummings III, spokesman for the Honolulu Department of Emergency Management.
The Honolulu International Airport remained open but seven or eight jets bound for Hawaii have turned around, including some originating from Japan, the state Department of Transportation said.
All harbors are closed and vessels were being ordered to leave the harbor.
The warnings issued by the Hawaii-based Pacific Tsunami Warning Center cover an area stretching the entire western coast of the United States and Canada from the Mexican border to Chignik Bay in Alaska.
In Alaska, a dozen small communities along the Aleutian Island chain were on alert. The first waves - about 1.5 feet - hit the western portions of the islands with no reported damage.
In Oregon, county officials in Oregon were assessing whether to sound sirens; waves in Brookings in southern Oregon could also hit 6 feet.
The tsunami was expected to hit the Northern Mariana Islands, a U.S. territory at 4 a.m. EST, but no big waves came. Waves about 2.6 feet (80 centimeters) high hit the beach in Saipan, and sirens still sounded in the empty streets.
In the Philippines, officials ordered an evacuation of coastal communities along the country's eastern seaboard in expectation of a tsunami following the 8.9-magnitude earthquake in Japan.
Disaster management officials in Albay province southeast of Manila say they ordered residents to move to designated evacuation sites that are at least 15 feet (4.5 meters) above sea level.
Evacuation orders were lifted in Guam.
Australia was not in danger because it was protected by island nations to the north, including Papua New Guinea and the Solomon Islands, that would largely absorb any wave activity, said Chris Ryan, a forecaster at the National Meteorological and Oceanographic Centre, the Australian government agency that monitors the threat.
The warning was issued Friday at 3:31 a.m. EST (0831 GMT). Sirens were sounded about 30 minutes later in Honolulu alerting people in coastal areas to evacuate. About 70 percent of Hawaii's 1.4 million population resides in Honolulu, and as many as 100,000 tourists are in the city on any given day.
Honolulu's Department of Emergency Management has created refuge areas at community centers and schools, and authorities on Kauai island have opened 11 schools to serve as shelters for those who have left tsunami inundation zones.
"The situation we're confronting right now is unpredictable. We do not know how many waves are going to be coming," said Honolulu Mayor Peter Carlisle. "We do not know which wave, if any wave, causes the most damage and how long the series of waves can last. As a result of that, it is our responsibility to do those things which are absolutely essential to ensure that human life is saved."
U.S. Coast Guard rescue crews were making preparations throughout the Hawaiian Islands to provide post-tsunami support, with cutter and aircraft crews positioning themselves to conduct response and survey missions.
The worst big wave to strike the U.S. was a 1946 tsunami caused by a magnitude of 8.1 earthquake near Unimak Islands, Alaska, that killed 165 people, mostly in Hawaii. In 1960, a magnitude 9.5 earthquake in southern
Chile caused a tsunami that killed at least 1,716 people, including 61 people in Hilo. It also destroyed most of that city's downtown. On the U.S. mainland, a 1964 tsunami from a 9.2 magnitude earthquake in Prince William Sound, Alaska, struck Washington State, Oregon and California. It killed 128 people, including 11 in Crescent City, California.
