The earthquake hit at 0815 GMT, at a depth of 30 km (18.6
miles) around 225 km (140 miles) southwest of Sungaipenuh town
in Jambi province, but there were no immediate reports of any
damage or casualties. The meteorology department did not issue a tsunami warning.
More than 20 people were killed when the 8.4 magnitude
earthquake hit Sumatra on Sept. 12, which was followed by a
series of strong aftershocks, setting off tsunami warnings in
Indonesia and other countries in the region.
Indonesia, which is situated in a belt of intense seismic
activity known as the "Pacific Ring of Fire", was hit by a huge
earthquake in December 2004, triggering a devastating tsunami
in the Indian Ocean, which killed more than 230,000 people in
the region, including 170,000 Indonesians.
