The shallow 6.9 quake hit just after 10pm local time was just one of 15 with a magnitude of 4.5 or higher which have struck the area in the past 24 hours.
The latest deadly tremor came just hours after another magnitude 6.3 quake, which is confirmed to have killed at least one person.
These recent quakes come after the devastating magnitude-6.9 on August 5 killed at least 460 people, displaced hundreds of thousands and destroyed vast swathes of the island’s buildings.
Six of those who died from last night’s earthquake were on the neighbouring island of Sumbawa.
The quakes, in the Sembalun district in the north-east of the island, caused panic, but many people were already staying in tents following the deadly quake earlier this month so avoided the damage.
The national disaster mitigation agency said power was cut across the island, hampering efforts to assess the situation.
Some houses and other buildings in Sembalun had collapsed, it said.
The quake lasted five to 10 seconds and also was felt in Bali and as far away as East Java and Makassar in Sulawesi.
Disaster agency spokesman Sutopo Purwo Nugroho said: “People panicked and scattered.
“Some people are hysterical because they feel earthquake aftershocks that are harder than before.
“They heard a roar that probably came from landslides in the hills and Mount Rinjani.”
Officials have warned that any buildings which remain standing have suffered repeated stress and could collapse at any time, urging people to stay clear.
The mountainsides are also said to pose a risk due to rock falls and landslides.
Lombok’s Mount Rinjani has been closed to visitors following a 29 July earthquake that killed 16 people, triggered landslides and stranded hundreds of tourists on the mountain.
Earthquakes are common in Indonesia.
The islands form part of the Pacific ‘Ring of Fire’, a massive horseshoe-shaped arc of seismic and volcanic activity.
The Ring of Fire accounts for about 90 percent of the world’s earthquakes and volcanic eruptions.
Sitting just between the Australian and Sunda tectonic plates, Lombok is at particular risk.
For Indonesia as a whole, a total of 557 quakes have taken place within the last year.
In the 2004 Indian Ocean tsunami which left 226,000 people dead across 13 countries, the largest number of casualties were from Indonesia, where 120,000 individuals died.
