A magnitude 7.2 earthquake struck in the sea, 124 kilometres north-northeast of the holiday island of Lombok, Indonesia, on Sunday at a very shallow depth of 1km, the United States Geological Survey said.

There was no immediate tsunami alert from the Pacific Tsunami Warning Centre.

Earlier on Sunday a tremor of 6.3 magnitude struck the island, where an earthquake earlier this month killed more than 430 people.
