A huge 5.6 magnitude earthquake hit the island of Java in Indonesia on Monday.
Data showed that the quake struck just 10km beneath the Earth’s surface.
Scores of people were taken to the hospital, with many treated outside.
Rescuers have worked through the night to try to save others thought to be still trapped under collapsed buildings.
Tremors could be felt as far away as the capital city, Jakarta, more than 60 miles away.
Officials are warning of possible aftershocks as rescue efforts get underway.
Indonesia is vulnerable to earthquakes as it lies along a fault line known as ‘the ring of fire. It is an area where tectonic plates float on top of a layer of softer, a squidgy rock called the mantle, under the Earth’s crust.
When the plates rub together, the movement forces waves of energy to come to the Earth’s surface.
