MOSCOW (Sputnik) – A 6.5-magnitude earthquake has occurred in South Sumatra, a province on the island of Sumatra in Indonesia, the Hong Kong Observatory (HKO) reports.
"Earthquake: 2016-06-02 06:56HKT M6.2 [2.4S,100.5E] in Southern Sumatra, Indonesia," HKO said on its earthquake alert Twitter account.
The US Geological Survey (USGS) said the earthquake’s preliminary magnitude was 6.5. According to USGS, the quake struck off the western coast of Sumatra, in the Kepulauan Mentawai region, at a depth of about 50 kilometers (31.5 miles).
