6.7 Magnitude Earthquake Rattles Indonesia
The quake struck off the west coast of the island at 8:52 a.m. local time and was "strongly felt," across west Sumatra and outlying islands, said Budi Waluyu, from the government's geophysical and meteorological agency.
Callers to el-Shinta radio station from Medan, a large city on Sumatra, said tall buildings shook and some residents ran from their homes.
The U.S. Geological Survey said the quake had a magnitude of 6.7 and was centered 120 miles west of the Sumatra town of Sibolga, 860 miles northwest of Jakarta.
Earthquakes have struck the region regularly since a monster 9.1 magnitude earthquake on Dec. 26 that triggered a tsunami, killing more than 176,000 people in Indonesia and 10 other countries across the Indian Ocean.ABC news
