The aftershock follows a series of quakes which have hit Indonesia over the past two weeks.
Houses damaged by an natural disaster are seen in North Lombok, Indonesia, Monday, Aug. 6, 2018.
Nyoman Sidekarya, chief of the provincial search and rescue agency that covers the Indonesian island of Lombok, tells The Associated Press that the death toll from the natural disaster that hit the island on Sunday is now 227.
Officials said the epicenter of the aftershock was on land and so there was no risk of a tsunami.
He said that after receiving reports about the powerful quake in Lombok, he had immediately ordered the heads of the National Disaster Mitigation Agency (BNPB) and the National Search and Rescue Agency (Basarnas), as well as chiefs of the Indonesian Defense Forces (TNI) and the National Police, to help evacuate victims and foreign tourists from Lombok Island, and to provide medical treatment and relief aid for the refugees.
Scientists say the powerful Indonesian quake that killed almost 400 people lifted the island it struck by as much as 25 centimetres (10 inches).

Muhamad Juanda, who narrowly escaped the mosque collapse, said 100 people were praying inside when the earth began to roll. However, a local search and rescue official said there had been at least one fatality on the Gilis and several injuries.
The quake struck at 19:46 local time (11:46 GMT) on Sunday at a fairly shallow depth of 31km (19 miles). As of August 8, a total 347 people were killed and 1,500 were injured. Until Tuesday (8/8), aftershocks still occurred after the quake with a magnitude of 7 hit Lombok Island, West Nusa Tenggara, on Sunday (5/8). The agency says it is has not verified these other figures but expects the toll to climb.
Sunday's quake came only days after a slightly smaller one, which killed at least 16 people.
Most of the displaced are sleeping under tents or tarpaulins near their ruined homes or in evacuation shelters that are short of food, clean water and medical help.
Motorcycles parked on the street were seen toppled over, while the walls of other nearby buildings collapsed.
"Our latest update is that 319 people died", the Agence Frence-Presse quoted Indonesia's chief security minister Wiranto as saying. Relief teams, deployed after Sunday's quake, have not yet managed to reach some sites on the island near the epicenter due to the access difficulties, Security Minister Wiranto said, quoted by The Jakarta Post.
He said they had later found and treated 40 people with broken bones, cuts and bruises.
