Tsunami warning after quake off Lombok

A magnitude 7.0 earthquake has struck off Indonesia, rattling the islands of Lombok and Bali and sending holidaymakers and residents into the streets.

Indonesia's resort islands of Bali and Lombok have been rocked by a magnitude 7 earthquake, prompting a tsunami warning and panic among holidaymakers, including Australians, and residents.

The quake, which struck at a depth of 15km off the north coast of Lombok on Sunday, comes a week after a magnitude 6.4 quake killed 14 people on the island and prompted a large-scale evacuation of a volcano popular with hikers.

There were no immediate reports of casualties.

The quake was felt for several seconds in Bali, where people ran out of houses, hotels and restaurants.

"All the hotel guests were running so I did too. People filled the streets," said Michelle Lindsay, an Australian tourist.

"A lot of officials were urging people not to panic."

Other witnesses said the quake got stronger over several seconds and rattled windows and doors in their frames.
