11 km WNW of San Agustín, Colombia

A magnitude 7.3 earthquake — a major event — struck near 11 km WNW of San Agustín, Colombia on September 30, 2012, at a intermediate-depth depth of about 170 km. An earthquake this size would have been felt strongly across the surrounding region; intermediate-depth events inside a subducting slab are often felt over a wide area but do less surface damage than shallow quakes. 599 people submitted "Did You Feel It?" shaking reports to the USGS. Casualties, damage and the recovery depend on local building standards, population and distance from the epicentre — the news coverage, references and photos below capture what happened on the ground.
