The Andes mountain range is a highly seismic zone. Colombia, in particular, is exposed to a very high seismic risk, being one of the few places in the world where three tectonic plates meet. The continent lies on the South American plate, the Gorgona and Malpelo islands lie on the Nazca plate, and the San Andres and Providencia islands lie on the Caribbean plate.

The country records an average of 50,000 earthquakes per month, although most are invisible to humans. Many of Colombia's major cities are located in the Andes mountain range or in the two large valleys that divide it into three mountain ranges, crossed by the Cauca and Magdalena rivers.

The epicenter of the August 10 earthquake was in the Western Cordillera, between the Cauca River and the Pacific Ocean. This is the area where some of the most destructive earthquakes have occurred:

In 1999, a magnitude 6.2 earthquake struck the city of Armenia, at about the same latitude but in the Cordillera Central, causing extensive damage and nearly a thousand deaths. In 1983, Popayán, further south in the Cordillera Western, was hit by an earthquake that caused 287 deaths.

According to the director of the Colombian Geological Survey, Julio Fierro Morales, the August 10 earthquake was the strongest Colombia has experienced in decades, since November 1979. At the time, it was 7.2.

According to him, the 7.4 magnitude earthquake was "the highest earthquake recorded in Colombia in the last decade" and was followed by two aftershocks of magnitude 2.8 and 4.8.
