JAKARTA, Indonesia — Indonesia lifted a tsunami warning issued Wednesday after a powerful earthquake off Sumatra sent islanders rushing to high ground.
The U.S. Geological Service said the earthquake had a magnitude of 7.8. It was centered under the ocean at a depth of 15 miles, it said.
Shallow earthquakes are more likely to cause damage, but the USGS said the quake was far from land, about 409 miles from the town of Muara Siberut.
Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho said no damage or casualties were reported so far, but panicked people in several cities and villages on Sumatra island and in the Mentawai island chain fled to higher elevations.
Indonesia, the world’s largest archipelago, is prone to seismic upheaval because of its location on the Pacific “Ring of Fire,” an arc of volcanoes and fault lines circling the Pacific Basin.
A massive magnitude-9.1 quake off Indonesia in 2004 triggered a tsunami that killed 230,000 people in a dozen countries. Most of the deaths were in Indonesia’s Aceh province.
