PAGO PAGO, American Samoa (AP) - A powerful earthquake with a magnitude of up to 8.3 struck in the South Pacific between Samoa and American Samoa around dawn Tuesday, sending terrified residents fleeing for higher ground as a tsunami swept ashore, flattening at least one village. There were no immediate reports of fatalities.
The quake hit at 6:48 a.m. Tuesday (1748 GMT) midway between the two island groups. In Apia, families reported shaking that lasted for up to three minutes. The U.S. Geological Service, which estimated the magnitude at 8.0, said the quake struck 20 miles (35 kilometers) below the ocean floor, 120 miles (190 kilometers) from American Samoa and 125 miles (200 kilometers) from Samoa, with a 5.6-magnitude aftershock 20 minutes later.
The Pacific Tsunami Warning Center put the quake's magnitude at 8.3 and issued a general alert for the South Pacific region, from American Samoa to New Zealand. It said there were indications a tsunami wave could be "destructive" along some coastlines. Several hours away from the epicenter, Hawaii was put under a tsunami watch, with five emergency centers opened as a precaution.
New Zealander Graeme Ansell said the beach village of Sau Sau Beach Fale was leveled.
"It was very quick. The whole village has been wiped out," Ansell told National Radio from a hill near Samoa's capital, Apia. "There's not a building standing. We've all clambered up hills, and one of our party has a broken leg. There will be people in a great lot of need 'round here."
A five-foot tsunami wave swept into Pago Pago, capital of American Samoa, shortly after the earthquake, sending sea water surging inland about 100 yards (meters) before receding, leaving some cars and debris stuck in mud. Electricity outages were reported, and telephone lines were jammed.
The staff of the port ran to higher ground, and police soon came by, telling residents to get inland. Several students were seen ransacking a gas station/convenience store.
In Fagatogo, water reached the waterfront town's meeting field and covered portions of the main highway, which also was plagued by rock slides.
In Samoa, the powerful quake jolted people awake.
"It was pretty strong; it was long and lasted at least two minutes," one resident told local radio.
"It's the strongest I have felt, and we ran outside. You could see all the trees and houses were shaking," he said.
Sulili Dusi told New Zealand's National Radio that "everything dropped on the floor and we thought the house was going to go down as well. Thank God, it didn't." Along with neighbors, they fled to high ground.
She said the tsunami hit the south side of the island, and some "cars have been taken." She did not elaborate, but added "we just thank God no life has been taken yet."
Another resident, Dean Phillips, said the southern coast of Upolu island had been struck by the tsunami.
"The police are sending everybody up to high ground," he said.
Local media said they had reports of some landslides in the Solosolo region of the main Samoan island of Upolu and damage to plantations in the countryside outside Apia.
There were no immediate reports of injury or serious damage from local emergency services, but people reported cracks in some homes and items tossed from shelves.
The Pacific Tsunami Warning Center in Honolulu issued a tsunami warning for numerous islands in the Pacific, including the Samoas, the Cook Islands, Tonga, Fiji, New Zealand, French Polynesia and Palmyra Island.
The center posted a tsunami watch for Hawaii, Vanuatu, the Marshall Islands, Solomon Island, Johnston Island, New Caledonia, Papua New Guinea, Wake Island, Midway Island and Pitcairn.
In New Zealand, a tsunami alert was issued by national Civil Defense, and the nation's national emergency center was activated.
