Indonesia's geological agency said the quake on Thursday afternoon had a magnitude of 6.2 and was shallow, at a depth of 12 kilometres, centred in the north-west of the island. A devastating natural disaster on Sunday killed hundreds, and a strong aftershock on Thursday caused panic among evacuees.
Meanwhile, the ministry issued a separate statement advising Korean people to refrain from traveling to Lombok.

The Indonesian military said that three Hercules transporter planes packed with food, medication, blankets, tents and water tanks had arrived in Lombok.
Indonesia's disaster mitigation agency spokesman Sutopo Purwo Nugroho: "Evacuees and people ran out of houses when they felt the strong shake of the 6.2 magnitude quake".
Thousands have been left homeless and in desperate need of clean water, food, medicine and shelter in Lombok.

Motorcycles parked on the street toppled over and the walls of some nearby buildings collapsed.
Indonesia is located on the Pacific "Ring of Fire".
The majority of the people died in Kayangan, on the north side of the island, Antara reported. "Some paramedics have to be at the shelters, some need to be mobile", Majdi said.
"We received information from our area team in West Nusa Tenggara that telecommunication access was down, while many people were still looking for their family members".
