JAKARTA — A 5.6-magnitude earthquake struck off the Indonesian island of Sumatra on Sunday, geologists said, although there were no immediate reports of damage or tsunami notices issued.
The undersea quake hit at a depth of 39 kilometres (24 miles) at 6:52 pm (11:52 GMT) around 115 kilometres west of Bengkulu in Sumatra, the US Geological Survey said, revising down an initial 5.9-magnitude estimate.
There were no tsunami warnings or advisories in effect on the website of the Hawaii-based Pacific Tsunami Warning Center.
Indonesia sits on the Pacific “Ring of Fire”, where the meeting of continental plates causes high seismic activity, and is frequently hit by earthquakes.
A powerful quake jolted the Indonesian resort island of Bali on October 13, injuring dozens of people and triggering panic as tourists fled from violently shaking buildings.
The 6.0-magnitude quake rocked the main tourist district of Kuta for several minutes, damaging ancient Hindu temples and sending concrete debris crashing down onto cars and pavements as walls and roofs collapsed.
