MATARAM, Indonesia 鈥� Multiple earthquakes 鈥� including a powerful and shallow 6.9-magnitude tremor 鈥� struck Indonesia鈥檚 Lombok on Sunday, sending fresh panic coursing through the already battered island.
Four significant quakes were recorded by seismologists on Sunday, the first measuring 6.3 shortly before midday which triggered landslides and sent people fleeing for cover.
It was followed nearly twelve hours later by a late evening quake measuring 6.9 and two aftershocks of 5.9 and 5.3 strength, according to the US Geological Survey.
The picturesque island is already reeling from two devastating quakes on July 29 and August 5 that killed nearly 500 people and made hundreds of thousands homeless.
There were no immediate reports of casualties or damage from the late evening quakes on an island where many have chosen to sleep in tents in recent weeks because of regular aftershocks.
One local resident said the powerful tremor jolted him awake.
鈥淭he earthquake was incredibly strong. Everything was shaking,鈥� Agus Salim told AFP.
鈥淲e were all sleeping in an evacuation tent. I had just fallen asleep when suddenly it started to shake鈥�. Everyone ran into the street screaming and crying.鈥�
A dozen foreign guests at the hotel Lina Senggigi, which is in a popular tourist spot, were ushered out of the building as the quake struck.
鈥淭he jolt was strong and quite long鈥� Tonight we will ask our guests to sleep in the parking lot. It鈥檚 safer that way,鈥� a staff member told Kompas TV.
National disaster agency spokesman Sutopo Purwo Nugroho tweeted that blackouts had hit much of the island after the evening quakes.
鈥淎ftershocks are still happening across Lombok,鈥� he tweeted. 鈥淚t鈥檚 pitch black鈥�. We are still coordinating with officials on the ground.鈥�
Landslides and collapsed buildings
Earlier in the day he said that the morning quake caused panic but no widespread reports of damage. One person died from a suspected heart attack and there were reports of localized damage.
Landslides were reported in a national park on Mount Rinjani where hundreds of hikers had been briefly trapped after the quake in late July. The park has been closed since then.
Local disaster mitigation agency spokesman Agung Pramuja said several houses and other structures in the district of Sembalun, on the slopes of Mount Rinjani, collapsed on Sunday after being damaged by the previous two quakes.
The structures included checkpoints once used by trekkers climbing the mountain, Pramuja said, adding that the exact number of damaged buildings was still being checked.
Sunday鈥檚 tremors were also felt on the neighboring resort island of Bali but there were no reports of damage.
鈥楻ing of Fire鈥�
The latest tremor comes two weeks after a shallow 6.9-magnitude quake on August 5 damaged tens of thousands of homes, mosques and businesses across Lombok.
At least 481 people died and thousands were injured.
The hardest-hit region was in the north of the island, which has suffered hundreds of aftershocks.
A week before that quake, a tremor surged through the island and killed 17.
The August 5 quake left more than 350,000 displaced, with many sleeping under tents or tarpaulins near their ruined homes or in evacuation shelters, while makeshift medical facilities were set up to treat the injured.
Badly damaged roads, particularly in the mountainous north of the island, are a headache for relief agencies trying to distribute aid.
The economic toll of the quake is estimated to be at least five trillion rupiah ($348 million).
Indonesia sits on the so-called Pacific 鈥淩ing of Fire鈥�, where tectonic plates collide and many of the world鈥檚 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. /cbb
