The quake, at a depth of 84 kilometres (52.2 miles), hit at about 3 a.m. local time (2000 GMT). A number of aftershocks were detected later, and one registered 5 magnitude, BMKG data showed. Local news footage showed some Padang residents evacuating by motorbike and foot to higher ground. Some carried backpacks while others huddled together under an umbrella against the rain. "On the Siberut island, people had already been evacuated. They have been told to stay at the evacuation area until tsunami warning is lifted," Noviandri, a local official told TvOne.
