'The jolt got much stronger': 4 killed as earthquake hits Indonesia's Papua

At least four people were killed on Thursday when an earthquake struck the capital of Indonesia's breakaway eastern region of Papua and crumpled a waterfront restaurant, officials said.

The 5.1-magnitude quake hit around 13:28 (06:28 GMT) on land just southwest of Jayapura city at a depth of 22km, the US Geological Survey said.

"A café collapsed and four people died there. It fell into the sea," Asep Khalid, head of the Jayapura disaster mitigation agency, said in a press release.

Residents in Jayapura said people scrambled for safety, running from houses and shops when the quake struck.

Putri Kurita, 30, bolted for the exit at another restaurant fearing it would collapse.

She told AFP:

The country's meteorological agency gave a higher magnitude of 5.2 and warned of potential aftershocks.

Indonesia experiences frequent seismic and volcanic activity due to its position on the Pacific "Ring of Fire", where tectonic plates collide.

The region affected by Thursday's quake is home to a decades-long insurgency waged by rebels seeking independence from Indonesia.
