Three tectonic elements converge on Colombia: the Nazca plate subducting along the Pacific coast, the Caribbean plate pressing from the north, and the Panama block colliding into the northwest. The Chocó margin off Buenaventura is the most active segment, capable of Mw 8 ruptures as in 1906 and 1979.

The emergency number in Colombia is 123, answered by UNGRD. After strong shaking, keep the line free for those trapped or injured and check official channels for aftershock and tsunami advisories.
The national seismic authority is Servicio Geológico Colombiano (SGC). EarthquakeLive cross-checks its bulletins against 18 international networks, so an event may appear here with a slightly different magnitude until the agencies converge on a final solution.
