At least 111 people have been killed after a powerful earthquake struck western Colombia, knocking down buildings across several cities and leaving others trapped in the rubble. A mix of residents and search teams picked through the rubble of collapsed buildings amid concerns by authorities of aftershocks. Authorities in the rural state of Choco, the epicentre of the quake, reported injured people and damaged buildings in the capital, but provided few details. Small earthquakes, known as “temblores,” are common in central and western Colombia, but those above 6.0 magnitude are rare. In 1999, a 6.2 magnitude quake near the city of Armenia killed more than 1100 people.
