Feb. 12 -- A magnitude-7.0 earthquake struck off the coast of Indonesia, triggering two aftershocks, the U.S. Geological Survey said. The temblor, with a depth of 21.7 miles (35 kilometers), hit about 175 miles south-southeast of General Santos in the Philippines, according to the USGS.
There is no "destructive widespread" tsunami threat from the quake, which struck at about 1:34 a.m. local time, the U.S. Pacific Tsunami Warning Center said. There were no immediate reports of injuries or damage.
Indonesia's meteorology and geophysics agency canceled a tsunami warning about an hour after the temblor struck just off the northeast tip of the island of Sulawesi, according to the Associated Press.
Two aftershocks were reported within about 50 minutes of the first quake, one of magnitude 5.6 and one of magnitude 5.9, the USGS said.
Indonesia lies in a zone where the Indo-Australian, Eurasian, Philippine and Pacific plates meet and occasionally shift, causing earthquakes and sometimes generating tsunamis. A 9.1-magnitude earthquake off Sumatra in December 2004 caused a tsunami that devastated coastal communities across the Indian Ocean, killing more than 220,000 people.
