A magnitude 7.4 earthquake has struck the Northern Molucca Sea region in Indonesia, the United States Geological Survey (USGS) said.
The quake, which hit early on Thursday local time, had depth of 35km and its epicenter was 127km (79 miles) west-northwest of Ternate, Indonesia, the USGS said.
The US tsunami warning system said tsunami waves were possible with 1,000km of the epicentre, along the coasts of Indonesia, the Philippines and Malaysia. It warned that tsunami waves reaching 0.3 metres to one metre (3.2ft) above the tide level were possible for some of the Indonesian coastline.
