Indonesia's geological agency said the quake Thursday afternoon had a magnitude of 6.2 and was shallow, at a depth of 12 kilometers, centred in the northwest of the island.
A Reuters witness said the latest quake sent people into the streets in panic and caused buildings to collapse.
Almost 1,500 people have been hospitalized with serious injuries and more than 156,000 have been displaced due to the extensive damage to thousands of homes.
The aftershock had caused more "trauma", said national disaster agency spokesman Sutopo Purwo Nugroho.More news: Get Meghan Markle's favorite designer sunglasses for less

Rescue workers were still digging through rubble and trying to reach survivors of Sunday's quake.
"I visited villages yesterday that were completely collapsed", he said, while other teams in East and North Lombok had reported villages where 75 percent of homes were damaged.
Many buildings still standing on the island have been weakened.
Aid agencies say the number is likely to increase dramatically as they gain access to the worst-hit parts of the island.
There is a dire need for medical staff and "long-term aid", especially food and medicine in the worst-hit areas, government officials said.
The Indonesian Red Cross said it had set up 10 mobile clinics in the north of the island.
Kurniawan Eko Wibowo, a doctor at the field hospital, said most patients had broken bones and head injuries.
