Venezuela's Rare Earthquake Doublet Kills 164, Disrupts Aftershock Forecasting

Two mainshocks of magnitude 7.2 and 7.5 ruptured northwestern Venezuela 39 seconds apart on June 24, 2026, a rare seismic doublet that killed at least 164 people. Strike-slip faulting along the Caribbean–South American plate boundary produced the paired ruptures. Doublets reset stress fields unpredictably, confounding standard aftershock models. Regional seismic monitoring infrastructure remains under-resourced for such scenarios.
