Another quake with a magnitude of 6.2 hit Indonesia's Lombok Island on Thursday.
Local authorities, worldwide relief groups and the central government have begun organising aid, but shattered roads have slowed efforts to reach survivors in the mountainous north of Lombok, which bore the brunt of the quake.
Officials said about three-quarters of Lombok's rural north had been without electricity since Sunday, although power had since been restored in most areas.
Indonesian authorities are appealing for food, clean water and medical help for some 156,000 people forced from their homes and 1,477 severely injured in the disaster.
Indonesia's geological agency said the quake was shallow, at a depth of 12km, centred in the northeast of the island. It did not have the potential to cause a tsunami, the agency added.
This most recent aftershock happened on Thursday and had a magnitude of 5.9.
Reuters news agency quoted a witness as saying the latest quake sent people onto the streets in panic and caused buildings to collapse.More news: Chelsea confirm signing Kepa Arrizabalaga on seven-year contract for £71.6m

YET ANOTHER powerful quake has struck the Indonesian island of Lombrok, next to Bali.
The death toll of Sunday's quake now stands at 319 but is likely to rise, according to Indonesia's chief security minister Wiranto, who like many Indonesians goes by one name.
The announcement came after an inter-agency meeting was called to resolve wildly different figures from different agencies.
Rescue teams search for victims in the rubble caused by an natural disaster at a mosque in North Lombok, Indonesia.
Almost 1,500 people are in hospital with serious injuries and more than 156,000 have been displaced due to the extensive damage to thousands of homes.
Indonesia is prone to earthquakes because of its location on the 'Ring of Fire, ' an arc of volcanoes and fault lines in the Pacific Basin.
The National Disaster Mitigation Agency said that at least 131 people were killed in Sunday's quake, but other agencies say the death toll has risen to more than 300. "For example, how we can deal with the number of damaged houses, mosques, schools, hospitals".
The military said five planes carrying food, medicine, blankets, field tents and water tankers left Jakarta for the island early Wednesday.
