A MODERATE 5.4-magnitude earthquake struck off the south of Indonesia’s Sumatra island on Monday, US geologists said. There was no immediate tsunami warning.
The quake struck at 10.55pm (1555 GMT, 11.55pm Singapore time) about 85km south-south-east of Bengkulu, on Sumatra island, at a depth of 73km, the US Geological Survey said in a preliminary report.
Indonesia sits on the Pacific ‘Ring of Fire’, where the meeting of continental plates causes high volcanic and seizmic activity.
A 7.6-magnitude quake that struck Sumatra island on September 30 killed more than 1,000 people.
