A strong, deep 7.1-magnitude earthquake and several aftershocks rattled Bali and other Indonesian islands on Tuesday, said the US Geological Survey (USGS).
The quake struck at a depth of around 515 kilometres off the northeastern coast of Bali at around 3:55 am local time (1955 GMT Monday).
The tremors were felt across Bali, and also in the nearby islands of Lombok and Sumbawa, reports AFP.
Bali residents said a second aftershock sent "longer and stronger" tremors than the first.
"When the first earthquake struck, I woke up my husband. Not long after that, the second earthquake struck, so we immediately took our children outside," said Ardylla Yuliacitra.
"The first earthquake made me sway like on a boat, and the second made my house tremble."
USGS said a 5.4-magnitude and another 5.6-magnitude aftershock within minutes of the initial quake.
Hotels evacuated their guests as staffers checked beaches for fear of a possible tsunami.
The epicentre was 181 km northeast of the Gili islands off Lombok, a short boat ride from Bali.
Indonesian authorities ruled out a tsunami and said no immediate damage was reported.
Indonesia experiences frequent earthquakes due to its position on the Pacific "Ring of Fire", an arc of intense seismic activity that stretches from Japan through Southeast Asia and across the Pacific basin.
