Jakarta: A 5.7-magnitude earthquake
struck off northern Indonesia`s Sumatra island on Tuesday, the US
Geological Survey (USGS) said, placing its epicentre near the
site of the devastating December 2004 quake.
There was no immediate tsunami warning.
The moderate quake struck Simeulue island at a depth
of 18 km at 9.07 pm local time (1937 IST), with its epicentre
312 km west of Medan on the Sumatra mainland and 315 km
southeast of Bandah Aceh, the USGS said.
The 9.1-magnitude earthquake of December 26, 2004, one
of the most powerful ever measured, struck in the strait
between Simeulue and Sumatra, triggering a tsunami that killed
more than 220,000 people around the Indian Ocean.
