Two strong tectonic quakes hit Bengkulu province of Indonesia's Sumatra island Sunday evening, but no casualties or injuries were reported.

The first struck at 19:34 hours (1234 GMT) with a magnitude of 5.3 on the Richter Scale, and the second at 19:40 with a 5.5 magnitude, Antara news agency Monday quoted the coordinator of the Meteorology and Geophysics Agency in Bengkulu, Adjat Sudrajat, as saying.

He said the epicenter of the first quake lies 3.2 degrees South Latitude and 100.45 degrees East Longitude, 30 kilometers deep, and 101 kilometers southwest of Muko-Muko district.

The epicenter of the second quake lies 3.14 degrees South Latitude and 100.78 degrees East Longitude, 72 kilometers southwest of Muko Muko in a depth of 10 kilometers.

Tremors continued striking the province after a 7.9 magnitude quake jolted it last month killing at least 15 people.
