Aid is now reaching isolated areas of the island while rescuers continued efforts to find the dead, pulling another body from the rubble.
More than 20,000 people have been displaced since the 6.9-magnitude quake struck Lombok, a popular tourist destination, on Sunday night.
For many, food and water remains in short supply and people are afraid to return to their homes - that is if they are still standing.
A woman's body was recovered from the rubble of a collapsed mosque on Wednesday morning in Bangsal district in the north of the island.
Sutopo Purwo Nugroho, a spokesman for the country's National Disaster Mitigation Agency, told reporters Monday that most of those killed and injured were on the northern side of Lombok, which sustained massive damage.
Rescuers have searched only a tiny portion of the 13,000 damaged buildings and they expect the death toll of more than 100 will rise significantly over the coming week.
Muhammad Zainul Majdi, the governor of West Nusa Tenggara province which covers Lombok, said there was a dire need for medical staff, food and medicine in the worst-hit areas.
A British tourist on the small Gili islands off the coast of Lombok described the panic that ensued to The Guardian: "The most terrifying part was the tsunami warning that followed". "Clean drinking water is scarce due to the extremely dry weather". It is expected to rise further because authorities believe people have been hit and killed by buildings including mosques, health clinics and houses which have collapsed.
Users took to Facebook to express concern for those affected by the natural disaster, employing the Indonesian word "selamat"-which can mean safe or unhurt, but can also mean congratulations depending on the context. Gili Air has run out of food and water so they have come to us", she told Reuters in a text message, adding later that she had been taken by boat to the main island en route to Bali".
"We will tear down our houses, they are too damaged to fix, we will rebuild with plywood and timber, it is safer, cheaper and warmer".
"People panicked and scattered on the streets, and buildings and houses that had been damaged by the previous quake had become more damaged and collapsed", Nugroho said.
It was the second deadly quake in a week to hit Lombok.
The worldwide charity Oxfam said drinking water was scarce because of a recent spell of extremely dry weather in Lombok. One Indonesian official told the BBC that 80 percent of the island had been impacted.
That quake killed at least 16 people and injured more than 300, according to The Washington Post.
Like Bali, Lombok is known for pristine beaches and mountains.
Lombok's airport was now open around the clock and had significantly increased its flight schedule. Hotels and other buildings in both locations are not allowed to exceed the height of coconut trees.
That's because the region sits smack-dab along the so-called ring of fire-an imaginary, horseshoe-shape line that follows the rim of the Pacific Ocean and marks spots where several tectonic plates collide.
