Venezuela doublet earthquakes may have been a single big one . Here why the science matters

Northern Venezuela experienced its largest tremors in over a century on Wednesday evening, with initial reports indicating a 7.2-magnitude earthquake followed 39 seconds later by a 7.5-magnitude quake, causing building collapses and over 100 fatalities. Scientists are investigating whether this was a rare "doublet" of two distinct earthquakes or a single, prolonged seismic event, a distinction crucial for understanding earthquake mechanics and prediction.
