Strong quake rocks Indonesia's Aceh

An earthquake measuring 7.1 on the Richter scale rocked Indonesia's Aceh province on Wednesday, but there were no immediate reports of casualties and damage, officials said.

The national earthquake centre issued a tsunami warning after the quake at 2:37 am (1937 GMT Tuesday) but lifted it an hour later, the Meteorology and Geophysics Agency said.

The quake's epicentre was 420 kilometres south-west of Banda Aceh, the capital of Aceh on the northern tip of Sumatra island, at a depth of 29 kilometres, according the US Geological Survey.

"We have not received reports of damage or casualties," said Sutopo Nugroho, a spokesman for the National Disaster Management Agency.
