JAKARTA, April 17 (UPI) -- Two more earthquakes, both 5.3 magnitude, hit South Pagai on the Mentawai Islands of Indonesia's West Sumatra early Friday, weather officials said.
The quakes followed a 6.0-magnitude tremor Thursday that shook island residents but caused no injuries or damage, as also was the case on Friday, the Jakarta Post said.
The Meteorology, Climatology and Geophysics Agency said the epicenter of the Friday incident was 43 kilometers, about 27 miles, southwest of South Pagai island. The island chain lies just off Padang, capital of an earthquake-prone province.
Some experts warn the area will bear the brunt of Indonesia's next major earthquake.
