A 7.6-magnitude earthquake struck late Saturday near the Solomon Islands, generating a tsunami warning for much of the South Pacific region, officials said.
The Pacific Tsunami Warning Center based in Hawaii said it did not know whether a tsunami had been generated, but issued a warning because of its strength. The warning area includes the Solomon Islands, Papua New Guinea, Vanuatu and Nauru.
A tsunami watch was issued for Guam, Australia, New Zealand and America Samoa.
The U.S. Geological Survey said the quake, initially estimated at a magnitude 8.3, occurred at a depth of about 10 kilometers (6 miles). The USGS said it occurred about 60 miles south-southeast of Kirakira, Solomon Islands.
