A powerful magnitude-7.8 earthquake struck near the Pacific's Solomon Islands, prompting the Pacific Tsunami Warning Center to warn that tsunami waves were possible in several South Pacific islands.
Soon after the quake, the Pacific Tsunami Warning Center canceled a tsunami watch it had issued for Hawaii.
The quake was centered about 120 miles southeast of Honiara, the capital of the Solomon Islands. The epicenter was relatively deep at 30 miles below the surface.
There were no immediate reports of damage or injuries. Deeper quakes generally cause less damage on the ground.
The Pacific Tsunami Warning Center cautioned that tsunami waves were possible in the Solomon Islands, Vanuatu, Papua New Guinea, Nauru, New Caledonia, Tuvalu and in Kosrae, in the Federated States of Micronesia.
Meantime, humanitarian organizations descended on Indonesia's Aceh province Thursday as the local disaster agency called for urgent food supplies and officials raced to assess the full extent of damage from Wednesday's earthquake that killed more than 100 people.
The Solomon Islands are located in the Pacific's geologically active "Ring of Fire."
