7.8 magnitude quake strikes off Indonesia coast
A 7.8 magnitude earthquake has struck off the coast of western Indonesia.
There have been no immediate reports of damage.
The US Geological Survey said the earthquake struck at 7:49 local time with an epicentre was 805 kilometres south-west of the city of Padang, and 24 kilometres deep.
Indonesian officials issued a tsunami warning for the regions of West Sumatra, North Sumatra and Aceh.
Australia also issued a tsunami warning for Cocos Island and Christmas Island in the Pacific.
It also issued a tsunami watch for Western Australia but this was later lifted.
Australia's Bureau of Meteorology said evacuations were not required on the islands but advised people to "get out of the water and move away from the immediate water's edge", because of the risk of dangerous waves and currents.
