A powerful earthquake rocked the northernmost Indonesian province of Aceh on July 2, injuring at least 50 people and damaging many houses.

Dozens were injured by collapsing buildings in Bener Meriah, one of the worst-hit areas

The magnitude-6.1 quake struck at a depth of just 10 kilometres and its epicentre was 181km southeast of the provincial capital Banda Aceh, the US Geological Survey was quoted as saying.

Indonesia sits on the Pacific "Ring of Fire" where tectonic plates collide, causing frequent seismic and volcanic activity.

Aceh, on the northern tip of Sumatra, is regularly hit by quakes.
