A magnitude 6.2 quake rocked Indonesia's Lombok on Thursday, with witnesses reporting collapsed buildings, the latest in a series of tremors on the tropical tourist island that have killed more than 150 people in the past two weeks. After the 6.9 magnitude quake in Lombok, Facebook users wrote "I hope people will survive". That number is expected to rise.
Buildings still standing on the island have been weakened after Sunday's natural disaster.
The quake struck as evening prayers were being said across the Muslim-majority island and there are fears that one collapsed mosque in north Lombok had been filled with worshippers.
Indonesia's national disaster agency has the official figure at 131 following the 7.0 magnitude quake which struck the north of the island - and also caused fatalities in neighbouring Bali.
A humanitarian crisis is also looming in Lombok, where thousands have been left homeless and in desperate need of clean water, food, medicine and shelter.
"The corpses are starting to smell and we believe some people buried are still alive - that's why it's a critical time", Nugroho said.
Almost 2,500 people have been taken to hospital with serious injuries and upwards of 156,000 people are displaced due to the extensive damage to homes.More news: Hurricane John absorbs tropical storm off Mexico
The quake was the second in a week to hit Lombok.
Thousands of people have been sleeping in makeshift shelters or out in the open.
Authorities said all the tourists who wanted to be evacuated from three outlying vacation islands due to power blackouts and damage to hotels had left by boat, some 5,000 people in all.
A green and yellow dome rested on the pile of rubble, the only part of the structure still intact.
Indonesia is prone to earthquakes because it lies on the Ring of Fire - the line of frequent quakes and volcanic eruptions that circles virtually the entire Pacific rim.
"The shaking seemed like it went for a bit longer than the main quake, but it was less intense".
