Geologist Explains Why Venezuela Suffered Consecutive Earthquakes and Predicts Future Events

Venezuela experienced a rare and devastating seismic event when two powerful earthquakes struck in rapid succession. The initial tremor registered a magnitude of 7.2, followed just a minute later by an even stronger quake of 7.5. This sequence surprised many, but geologist Andrés Folguera of the University of Buenos Aires explained it as a documented, though exceptionally destructive, scientific phenomenon known as a double earthquake.

Between a 7.2 and a 7.5 earthquake, there is approximately a tenfold difference in energy. The 7.2 damaged the infrastructure, and the 7.5 finished knocking it down. It's a terrible academic and scientific coincidence.

Folguera detailed that both seismic events originated on the Oca fault, a significant geological structure running through northern Venezuela parallel to the Caribbean Sea. He noted that the first earthquake severely damaged infrastructure, and the subsequent, more powerful tremor then caused the complete collapse of these already compromised structures. "Between a 7.2 and a 7.5 earthquake, there is approximately a tenfold difference in energy. The 7.2 damaged the infrastructure, and the 7.5 finished knocking it down. It's a terrible academic and scientific coincidence," he stated.

The geologist elaborated on the exponential nature of earthquake magnitudes, explaining that each degree increase represents about 33 times more energy. He identified the Oca fault as a structure that ruptures approximately every 100 years, citing historical occurrences in 1812, 1900, and now 2026. Folguera described the process as tectonic plates becoming locked for decades, accumulating immense tension until the deformation is suddenly released, causing the earthquake.

Every hundred years it produces an earthquake of this magnitude. It happened in 1812, it happened again in 1900, and it has happened again now in 2026.

Unlike regions like Chile where tectonic plates subduct, Venezuela's fault mechanism involves lateral movement. The plates slide past each other, building up energy until it overcomes rock resistance and releases abruptly. Folguera confirmed that the Oca fault is well-studied, allowing for precise identification of areas prone to future major seismic activity. He also cautioned that aftershocks are expected, and similar events will likely recur.

For a hundred years they are locked, and one day that deformation is suddenly released. That is what happened. Last night it was released.
