A powerful earthquake has flattened houses and toppled bridges on the Indonesian tourist island of Lombok, killing at least 98 people and shaking neighboring Bali.
Authorities said on Monday that rescuers still hadn't reached some devastated areas and the death toll would climb.
It was the second deadly quake in a week to hit Lombok.
A July 29 quake killed 16 people and damaged hundreds of houses, some of which collapsed in Sunday evening's 6.9 magnitude quake, killing those inside.
National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho told a news conference that damage was "massive" in northern Lombok. In several districts, more than half the homes were destroyed or severely damaged.
The ruins of a mosque that collapsed in Lading-Lading village while people prayed inside was being pulled apart by a backhoe in search of victims.
Some areas still hadn't been reached as of midafternoon on Monday, with rescuers battling collapsed bridges, electricity and communication blackouts and damaged roads blocked with debris.
Nugroho said the death toll had risen to 98, after warning earlier that it would "definitely increase." More than 230 people were seriously injured. Thousands of homes and buildings were damaged and 20,000 people were in temporary shelters.
The quake struck at a shallow depth of 10.5km in the northern part of Lombok. Shallow quakes tend to cause more damage than deeper ones.
"We were sitting there having dinner at about 7 o'clock last night, we just felt a really big sort of shaking and the lights went off and everyone just ran," Australian tourist Kim Liebelt said as he waited with other travellers for a flight out at Lombok's international airport.
"And then the roof started falling down on us, rocks and rubble and then just everyone running to get away," he said.
Videos showed screaming people running in panic from a shopping mall and a neighbourhood in Bali.
On Lombok, soldiers and other rescuers carried injured people on stretchers and carpets to evacuation centres.
"People panicked and scattered on the streets, and buildings and houses that had been damaged by the previous earthquake had become more damaged and collapsed," Nugroho said.
The quake triggered a tsunami warning, and frightened people poured out of their homes to move to higher ground, particularly in North Lombok and Mataram, the capital of West Nusa Tenggara province. The warning was lifted later Sunday after only small waves were recorded.
On Gili Trawangan, one of three popular vacation islands near Lombok, thousands of tourists and local residents spent the night on a hill fearing a tsunami.
Nugroho said authorities had deployed three ships to evacuate people.
By late Monday evening no Australians had been reported hurt in the quake.
Australian Home Affairs Minister Peter Dutton, in Lombok for a regional security meeting, said he and his delegation were in their hotel's 12th floor restaurant when the quake struck, plunging the building into darkness.
"Mate, we were knocked certainly to the floor. It was the violence of the shaking of the building - was pretty dramatic," he said in a radio interview. "Everyone's a bit shaken, but all well, but people out in the villages or elsewhere haven't been so lucky, unfortunately."
