Jakarta - An undersea earthquake registering 6.0 on the Richter scale struck the western coast of the Indonesian island of Sumatra Friday afternoon, but there were no reports of injuries or damage, the Indonesian seismologist agency said.
The quake struck at 1:37 pm (0637 GMT) and was centred in the Indian Ocean, 140 kilometres south-east of Mentawai island, off the western coast of Sumatra, Indonesia's National Meteorology and Geophysics Agency said.
While it occurred only 10 kilometres beneath the seabed, the quake did not trigger a tsunami, the agency said.
