6.2 magnitude

The 6.2-magnitude earthquake struck on Friday morning, just hours after an earlier, smaller tremor.

Hundreds of people were injured and thousands displaced by the quake.

Indonesia has a history of devastating earthquakes and tsunamis, with more than 2,000 killed in a 2018 Sulawesi quake.

Eight people died when the five-storey Mitra Manakarra Hospital in Mamuju partially collapsed on Friday, officials said. About 60 people were safely evacuated from the hospital.

The US Geological Survey says the epicentre was 133 kilometres northwest of Vanuatu, and there was no tsunami warning.

It was the fourth quake to hit the region in about a week, with a 6.9-magnitude earthquake striking off Vanuatu’s Vanua Lava island last Thursday.
