A 7.3 magnitude quake struck in the west coast of Northern Sumatra in Indonesia on Wednesday, January 11, 2012, according to a report by the US Geological Survey (USGS). The 7.3 quake has triggered the issuance of a tsunami warning by Indonesia‘s Meteorology and Geophysics Agency and the Pacific Tsunami Warning Center (PTWC). The tsunami alert was lifted two hours later.

The USGS reported that the 7.3 quake has a depth of 29 kilometers. It was reportedly felt at 2:37 a.m. around the 261 miles area of southwest Banda Aceh, capital of Sumatra, Indonesia’s Aceh province.

The Indonesian agency earlier reported a 7.6-magnitude quake which was downgraded later to 7.1. Aftershocks were registered at magnitude 5.4 and 5 at an interval of 30 minutes and an hour. The agency said that there were no immediate reports of casualties.

The PTWC explained in a statement that “There is a very small possibility of a local tsunami that could affect coasts located usually no more than a hundred kilometres from the earthquake epicentre.”
