A major earthquake on the Indonesian island of Lombok has killed at least 82 people, injured hundreds and damaged buildings, officials have said.

The National Disaster Mitigation Agency in Indonesia said this evening that the death toll following the deadly quake had risen to 82 from a previous toll of 32 

The agency added that thousands of people have been evacuated from Lombok island.

The 7.0 magnitude tremor struck just 10km underground, according to the US Geological Survey.

It was followed by two light to moderate secondary quakes and nearly two dozen aftershocks.

Among the dead are a one-year-old child and a 72-year-old, he said, adding that at least 52 people were injured.

Officials issued a tsunami warning after the quake, but it was later cancelled.

Seawater up to 13 centimetres deep poured into two villages, the head of the agency for meteorology, climatology and geophysics, told local TV.

The quake caused light damage as far away as the Javanese city of Bandung, some 955km from Mataram, but was felt strongly on the neighbouring resort island of Bali.

It triggered landslides that briefly trapped trekkers on popular mountain hiking routes.

"Please go to a place with higher ground, while remaining calm and not panicking," officials from the agency for meteorology, climatology and geophysics, said.

A spokesman for Indonesia's disaster mitigation agency, said many buildings were thought to have been damaged in Lombok's main city of Mataram.

"They are mostly buildings with weak construction material," he said.

Residents in Mataram described a strong jolt that sent people scrambling out of buildings.

One resident said the quake knocked out electricity and patients were evacuated from the main hospital.

The epicentre was in the sea 18km northwest of Lombok, the USGS said, far from the main tourist spots on the south and west of the island.

The USGS reported two aftershocks, one with a magnitude of 5.4.

People could be heard screaming as locals and tourists ran onto the road.

The tremor came a week after a shallow 6.4-magnitude quake hit Lombok, killing 17 people and damaging hundreds of buildings.

It triggered landslides that briefly trapped trekkers on popular mountain hiking routes.

Indonesia, one of the most disaster-prone nations on earth, straddles the so-called Pacific "Ring of Fire", where tectonic plates collide and many of the world's volcanic eruptions and earthquakes occur.

In 2004 a tsunami triggered by a magnitude 9.3 undersea earthquake off the coast of Sumatra in western Indonesia killed 220,000 people in countries around the Indian Ocean, including 168,000 in Indonesia.
