SYDNEY -- A powerful earthquake in the South Pacific generated a tsunami Wednesday prompting warnings to several island nations and sent residents fleeing for higher ground.
The Pacific Tsunami Warning Center said a tsunami of about 3 feet was measured in Lata wharf, in the Solomon Islands. The center said a 4.8-inch wave was observed in neighboring Vanuatu. No damage was immediately reported in either island nation.

The statement said the waves could be destructive near the epicenter and threaten more distant coasts.
The tsunami formed after an 8.0-magnitude earthquake near Lata in Temotu province, the easternmost province of the Solomons, about a 3-hour flight from the capital, Honiara. The region has a population of around 30,000 people.
In Honiara, the warning prompted residents to flee for higher ground.
"People are still standing on the hills outside of Honiara just looking out over the water, trying to observe if there is a wave coming in," said George Herming, a spokesman for the prime minister. So far, he had received no reports that a wave had been spotted in Honiara.
Atenia Tahu, who works for the Solomon Islands Broadcasting Corp. in Honiara, said most people were remaining calm.
"People around the coast and in the capital are ringing in and trying to get information from us and the National Disaster Office and are slowly moving up to higher ground," Tahu said. "But panic? No, no, no, people are not panicking."
The tsunami warning also covered Nauru, Papua New Guinea, Tuvalu, New Caledonia, Kosrae, Fiji, Kiribati, Wallis and Futuna. A tsunami watch, a less-severe rating, was in effect for American Samoa, Australia, New Zealand and eastern Indonesia.
An official at the disaster management office in Vanuatu said there were no reports of damage or injuries there.
More than 50 people were killed and thousands lost their homes in April 2007 when a magnitude 8.1 quake hit the western Solomon Islands, sending waves crashing into coastal villages.
The Solomons comprise more than 200 islands with a population of 552,000 people. They lie on the "Ring of Fire" -- an arc of earthquake and volcanic zones that stretches around the Pacific Rim and where about 90 percent of the world's quakes occur.
The U.S. Geological Survey said the quake struck 50 miles west of Lata, at a depth of 3.6 miles. Hawaii and the mainland U.S. were not affected.
