Fifty-four people have been killed and hundreds are injured after a powerful earthquake hit Indonesia's Aceh province.
The quake also caused dozens of buildings to collapse in a district near the epicentre.
Dozens of people are being treated outside hospitals in Pidie Jaya disrict as residents fear an aftershock, says deputy district chief Said Mulyadi.
The US Geological Survey says the shallow 6.4-magnitude earthquake that struck at 5:03am on Tuesday (local time) was centred about 10 kilometres north of Reuleut in northern Aceh, at a depth of 17.2 kilometres.
Indonesia's Climate, Meteorology and Geophysics Agency says the quake has no potential to trigger a tsunami.
A local disaster official has told local MetroTV that a woman and her two children were killed in Pidie Jaya, southwest of the epicentre.
He says several mosques in Pidie Jaya collapsed as well as stores, houses and other buildings and heavy equipment has been deployed in the search for survivors.
Indonesia is prone to earthquakes due to its location on the Pacific 'Ring of Fire', an arc of volcanoes and fault lines in the Pacific Basin.
In December 2004, a massive earthquake off Sumatra island triggered a tsunami that killed 230,000 people in a dozen countries.
