The two major earthquakes that struck Venezuela just 39 seconds apart on June 24 had slightly different epicenters in north-central Venezuela. The first (M7.2) struck near San Felipe, and the second (M7.5) near Yumare, leaving thousands dead and thousands more injured, according to government officials. But beyond the devastation, the sequence opened a rare scientific opportunity: Researchers think the unusual “earthquake doublet” could offer new insight into how large fault systems interact and how some of the most destructive earthquakes grow.
Large earthquakes are typically followed by smaller aftershocks. But particularly intense events can also alter stress on nearby faults or along the same fault, triggering another major earthquake.
