A POWERFUL earthquake jolted Indonesia’s popular resort island of Bali today, causing widespread panic and injuring at least 50 people.

The walls of some temples along the coast crumbled and witnesses told local radio and television stations the roofs of some homes collapsed.

Those injured suffered broken bones and head wounds.

The US Geological Survey said the 6.0-magnitude quake was centred 60 miles south west of the island. It hit 36 miles beneath the ocean floor.

Although not strong enough to trigger a tsunami, the quake was felt on neighbouring Java and Lombok islands, hundreds of miles away.

“It knocked me off my motorcycle,” said badly-shaken Bali resident Miftahul Chusna.

Candy Juliani, a public relations officer for the Sanur Beach Hotel, said terrified guests fled the building.

“We have special emergency routes for this type of situation, but everyone was so scared, they just ignored them,” she said.

At least 50 people were hurt, many with cuts, broken bones and head wounds, said Wayan Sudanti, a hospital spokesman. Three were in a critical condition.

Indonesia straddles a series of fault lines that makes the vast island nation prone to volcanic and seismic activity.

A giant quake off the country on December 26 2004 triggered a tsunami in the Indian Ocean that killed 230,000 people, half of them in Indonesia’s westernmost province of Aceh.
