Colombia’s earthquake reveals why depth matters
Inside Colombia's big quake – and why more could be coming
The episode shows how tectonic complexity shapes earthquake damage while practical protections remain possible despite the limits of prediction.
- 1Scientists can forecast earthquake risks across regions but cannot predict exactly when or where the next rupture will occur.
- 2Earthquake depth, fault structure, and aftershock behavior help explain why similar magnitudes can produce very different damage.
- 3Hazard maps, resilient construction, early-warning systems, and safe behavior reduce risk without requiring precise prediction.

Rodrigo León Loya explains why Colombia’s deeper earthquake caused less damage than a shallower Venezuelan event, despite their comparable scale.
The brief
Earthquake geologist Rodrigo León Loya describes experiencing Colombia’s magnitude 7.4 earthquake roughly 150 miles from its epicenter, where scientific curiosity competed with fear.
Loya separates forecasting from prediction: scientists can estimate broad earthquake risks, but no method can identify the exact time and location of the next rupture.
Colombia’s Nazca, South American, and Caribbean plates create several earthquake sources, while depth determines how much seismic energy reaches the surface.
The episode contrasts Colombia’s deeper event with a shallower Venezuelan earthquake involving multiple fault segments, showing why magnitude alone cannot explain damage.
Because prediction remains impossible, Loya turns to hazard maps, stronger buildings, early warning, and staying calm, holding on, and avoiding flight during shaking.
