An earthquake measuring 5.7 on the Richter scale struck the city of Sukabumi in Indonesia's West Java province today.

Indonesia's meteorology, climatology and geophysics agency said the quake was centred 193 kilometres south-west of Sukabumi at a depth of 10 kilometres. There were no reports of casualties or material damage.

Earthquakes hit various parts of Indonesia regularly. The country lies on the Pacific belt known as the Ring of Fire, where several tectonic plates meet, causing frequent volcanic and seismic activity.
