AlQa'dah 4, 1432, Oct 2, 2011, SPA -- An earthquake measuring 4.3 on the Richter scale hit the West Sumatra provincial capital of Padang on Sunday forcing many residents to stay outdoors. The epicenter of the quake which struck at 01.06 p.m. on Sunday was in the sea 77 km northwest of Padang at a depth of 10 km, ANTARA quoted the Meteorology, Climatology and Geophysics Agency (BMKG) as saying. The temblor was not significant enough to cause a tsunami, the agency said. Sunday's quake was strongly felt by local people, particularly those staying at storied buildings. However, no fatalities or injuries were reported.
