A 6.7-magnitude tremor with an epicenter 46 kilometers (28.5 miles) beneath the Indian Ocean's bed hit the island at 8:26 a.m. local time (1:26 p.m. GMT), and authorities issued a tsunami warning. No casualties have been reported so far.
On Wednesday, shocks measuring from 6.1 to 8.0 on the Richter scale, struck 105 kilometers (65 miles) southwest of Bengkulu, on the island of Sumatra, at a depth of 15.6 kilometers (9.7 miles), the U.S. Geological Survey said.
Buildings were reported to have swayed along the coast of Sumatra, and there have been reports of widespread panic as people headed inland. Three people were trapped in a collapsed office building in Padang.
On December 26, 2004, an earthquake off the coast of Sumatra, measuring 9.0 on the Richter scale, generated a huge tsunami that killed more than 150,000 in a dozen nations, the majority in Indonesia's Aceh province.
