People look at the damaged office of governor of West Sulawesi following an earthquake in Mamuju, West Sulawesi province.
At least 34 people have been killed and hundreds injured following a strong earthquake that shook Indonesia's Sulawesi island early on Friday morning, prompting landslides and destroying houses.

Thousands of people fled their homes to seek safety when the 6.2-magnitude earthquake hit just after 1am local time on Friday morning. The epicentre was six kilometres north-east of Majene city in West Sulawesi.

Hundreds of buildings have been destroyed or damaged, including a hospital, which has collapsed with more than a dozen patients and staff remain trapped beneath it.

"The hospital is flattened," said Arianto, who goes by one name, from the rescue agency in Mamuju city, near to Majene. Rescuers were also trying to reach a family of eight buried beneath the rubble of their destroyed home, he added.

The death toll includes 26 people in Mamuju city. "That number could grow but we hope it won't," said Ali Rahman, head of the local disaster mitigation agency. "Many of the dead are buried under rubble."


Comment: Update: The Daily Mail on January 17 reports:
Death toll rises to 73 in Indonesia earthquake that saw 28,000 flee their homes

The death toll from an earthquake that struck Indonesia's West Sulawesi province on Friday has risen to 73 as experts warn another quake could trigger a tsunami.

More than 820 people were injured and over 27,800 fled their homes after the 6.2-magnitude quake hit, a spokesman from the disaster mitigation agency (BNPB) said.


Some sought refuge in the mountains, while others rushed to cramped evacuation centres, witnesses said.

BNPB spokesman Raditya Jati said police and military officers have been deployed to crack down on looting in several parts of the region.

An emergency response status, intended to help rescue efforts, has also been put in place for two weeks, he said.

The epicentre of the quake which struck at around 1.30am on Friday was 22 miles south of the city of Mamuju and it had a relatively shallow depth of 11 miles, the United States Geological Survey said.

The earthquake came after a 5.9-magnitude tremor and at least 26 aftershocks the previous day, in a string of disasters which caused three landslides and damaged bridges to regional hubs such as the city of Makassar.

The tremors also damaged more than 60 homes, two hotels and the provincial governor's office. Electricity in the area is also out.

Jati's comments came as Dwikorita Karnawati, the head of Indonesia's meteorological, climatology and geophysical agency (BMKG), warned that another quake in the region could potentially trigger a tsunami.

The epicenter
A strong 6.7-magnitude earthquake has struck a lake along the Russia-Mongolia border, with shaking felt across the region, seismologists and residents say. There were no immediate reports of injuries.

The earthquake struck at 5:33 a.m. local time on Tuesday and was centered in Lake Khövsgöl in northern Mongolia, about 55 kilometers (34 miles) from the border with Russia, or 288 km (179 miles) southwest of Irkutsk.

The U.S. Geological Survey (USGS) put the earthquake's magnitude at 6.7, down from an earlier estimate of 6.8. It said the quake struck at a depth of just 10 km (6 miles) and was felt across the region on both sides of the border.

The area near the epicenter is not heavily populated but is home to a number of villages near the lake, including Hatgal and Turt, which have a combined population of up to 5,000 people. There were no immediate reports of casualties.
