MATARAM, Indonesia — A strong earthquake jolted the Indonesian island of Lombok on Sunday, causing landslides and damaging buildings as it tries to recover from a quake earlier this month that killed 460 people.The U.S. Geological Survey estimated the depth of the latest tremor at 4.9 miles and said the epicenter was on the north-eastern shoulder of the tourist island, at the foot of Mount Rinjani. There was no tsunami warning, and authorities were still awaiting word on casualties.Lombok, which lies just east of Bali, the southeast Asian country's most famous tourist destination, has been rocked by a series of quakes and aftershocks since July 29, including a 6.9-magnitude tremor on August 5.The latest tremor sent shudders through residents."It was very strong. All the lights went out," Asmaatul Husna told Reuters at a shopping mall where she works in Lombok's main town, Mataram.Disaster mitigation agency spokesman Sutopo Purwo Nugroho said there were no reports so far of casualties or damage."We are still monitoring," he told TVOne television.He said that activity on the island was normal and Mount Rinjani, where hundreds of trekkers were stranded after the July 29 quake, was closed and there were no tourists there.Indonesia, a sprawling archipelago that straddles the Pacific "Ring of Fire," is prone to earthquakes and volcanic eruptions.Lombok suffered damage running to more than $340 million from the August 5 quake, authorities said last week, putting the death toll at more than 430.More than 350,000 people fled their homes after that quake to shelter in government-provided tents or makeshift structures in open fields. Authorities said aid was slow getting to some of the hardest-hit areas as they are remote.
