JAKARTA, Indonesia—A 6.1 magnitude earthquake struck off the coast of Indonesia’s Sumatra island on Aug. 29, according to the country’s geophysics agency.
Indonesia’s meteorology and geophysics agency (BMKG) recorded the shallow quake off the Mentawai islands, off Sumatra’s west coast just before 10:30 a.m. local time; the agency said it didn’t trigger a tsunami warning.
The agency had earlier recorded a magnitude of 6.4 but revised that to 6.1, a BMKG spokesperson said.
Three consecutive earthquakes struck the area with increasing intensity beginning in the early hours of Aug. 29, with a 5.2 magnitude temblor recorded before dawn, followed by a 5.4 magnitude quake less than an hour later.
The 6.1 earthquake was felt strongly for several seconds by residents in the Mentawai islands, in the provincial capital of Padang, and in the surrounding mountainous area of Bukitinggi, the disaster agency said in a statement.
The agency said there were no reports of casualties but there was minor damage to buildings on Siberut island.
Separately, Novriadi, a local disaster official in the Mentawai islands, told Reuters that residents in several villages had been evacuated to higher ground and a local church, school, and health facility had been slightly damaged.
The nation’s disaster agency urged the public not to panic and warned of the potential for aftershocks.
Padang was struck by a 7.6-magnitude earthquake in 2009 that killed more than 1,100 people, injured many more, and caused widespread destruction.
Indonesia straddles the so-called Pacific Ring of Fire, where different tectonic plates of the Earth’s crust meet and create a large number of earthquakes and volcanoes.
