Indonesia was hit by its second earthquake in just over two weeks earlier today when a quake measuring 6.1 on the Richter scale struck in the Sunda Strait off the coast of Java, around 200 kilometres to the west of the capital Jakarta.

Buildings in the capital swayed for several minutes, but there appears to be little damage and so far there are no reports of casualties. The earthquake on 30 September which measured 7.6 on the Richter scale killed at least 1,115 people on the island of Sumatra.

Indonesia is often struck by earthquakes because it is situated on one of the world's most active fault lines, the Pacific Ring of Fire.
