Officials said the death toll from Sunday's quake, which was centred on the northern part of Lombok, but was also felt on the resort island of Bali to the west, stood at 16.
More than 600 were stranded on the side of the volcano but successfully climbed down the day after the quake struck, once landslides and debris were cleared from the two main paths by rescuers.
More than 220 people suffered serious injuries in the quake, Mr. Sutopo said.
Authorities expected 500 trekkers to arrive at the foot of the mountain by 5pm, said Agung Pramuja, a disaster mitigation official in Indonesia's region of West Nusa Tenggara.
Some 800 trekkers and their guides were on the mountain when the quake struck including citizens from the United States, France, the Netherlands, Thailand, Germany and 21 other countries, according to search and rescue officials.
The natural disaster has killed at least 16 people and caused landslides but no Thais were reported harmed, according to reports.
