A 5.6-magnitude earthquake jolted Indonesia’s Sumatra Island on August 25, the country’s Meteorology and Geophysics Agency has said.

The quake struck the island, in Aceh province, at 11:00 a.m. local time. Its epicentre was 166 kilometres southwest and 10 km deep, the agency was quoted as saying.

Indonesia faces regular earthquakes due to its position in a vulnerable quake-hit zone called "the Pacific Ring of Fire."

The country’s most devastating earthquake happened in Sumatra in 2004. A tsunami resulting from the quake killed 170,000 people in Aceh, a province on the northern tip of Sumatra, and tens of thousands more in countries around the Indian Ocean.-VNA
