Venezuela’s Powerful Earthquakes Were a Rare ‘Seismic Doublet’
Venezuela declared a national emergency following two earthquakes of 7.2 and 7.5 magnitude that occurred just 39 seconds apart on Wednesday. This phenomenon, known as a seismic doublet, is rare.
However, there are documented cases in various regions of the world that continue to be studied to expand our understanding of the mechanisms of stress is transferred within the Earth’s crust and the interaction between geological faults.
The US Geological Survey reported that both earthquakes had their epicenters northwest of the town of Yumare, near the city of Morón and about 160 kilometers (99 miles) west of the Venezuelan capital of Caracas. The quakes occurred at depths of 20.3 and 10 kilometers and were felt across much of northern Venezuela and in several Caribbean countries.
The sequence was classified as a severe seismic doublet, a phenomenon that occurs when two earthquakes of similar magnitudestrike almost simultaneously in nearby areas....
