An earthquake measuring 6.2 on the Richter scale rattled Indonesia's Nias Island early Wednesday, leaving one person dead and four others injured, ANTARA reported. The tremor was also believed to have caused cracks in tens of house buildings in Gunungsitoli sub district on the island, spokesman for the Medan Meteorology and Geophysics Office Rifwar Kamin said. The quake was also felt by people living along the western coast of North Sumatra province. The epicenter of the quake was in the sea about 24 km north west of the island at a depth of 10 km, he said. Wednesday's quake did not have the potential to cause tsunami, he said.
