The death toll from a strong and shallow earthquake has risen to at least 14 people on Indonesia's Lombok Island.

It injured more than 160 on the popular tourist destination next to Bali.

The quake damaged more than 1000 houses and was felt in a wider area, including on Bali, where no damage or casualties were reported.

The US Geological Survey said the quake struck at a depth of only 7km. Shallow earthquakes tend to do more damage than deeper ones.

East Lombok district was the hardest hit with 10 deaths, including a Malaysian tourist, said Sutopo Purwo Nugroho, a spokesman for Indonesia's Disaster Mitigation Agency. The number of casualties could increase as data was still being collected from other locations on the island, he said.

At least 162 people were injured, including 67 hospitalised with serious injuries, Nugroho said.

The quake caused blackouts in East Lombok and North Lombok districts and triggered a large landslide from Mt Rinjani, an active volcano. Rescuers were evacuating more than 800 tourists from the mountain.

In East Lombok and the provincial capital of Mataram, the quake lasted about 10 seconds, causing residents to flee their homes onto streets and fields, Nugroho said. He said most of the fatalities and injuries were caused by falling slabs of concrete.

Photos released by the disaster agency showed damaged houses and the entrance to the popular Mt Rinjani National Park, which was immediately closed for fear of landslides.

Television footage showed residents remaining outside, fearing aftershocks, as the injured were being treated on mattresses taken out of their partially damaged houses and patients were wheeled out of a hospital.

Eka Fathurrahman, the police chief in East Lombok, said the Malaysian woman who died was part of a group of 18 Malaysian tourists who had just visited Mt Rinjani when the quake jolted their guesthouse and toppled a concrete wall. Six other people were injured at the guesthouse.

 

Fathurrahman said many injured people who were treated outside a damaged clinic were evacuated to the main hospital farther away after more ambulances reached the devastated location in East Lombok's Sembalun village.

"Residents refused to enter their houses as prolonged aftershocks are still being felt," he said.

Indonesia's meteorology and geophysics agency recorded more than 130 aftershocks.

Like Bali, Lombok is known for pristine beaches and mountains. Hotels and other buildings in both locations are not allowed to exceed the height of coconut trees.

Indonesia is prone to earthquakes due to its location on the Pacific "Ring of Fire," an arc of volcanoes and fault lines in the Pacific Basin.

In December 2004, a massive magnitude 9.1 earthquake off Sumatra triggered a tsunami that killed 230,000 people in a dozen countries.
