Experts Study Catastrophic Venezuelan Doublet Earthquakes
Last Wednesday, June 24th of 2026, at 6:04 p.m. local time, an earthquake with a magnitude of 7.2 struck Northern Venezuela in the Yaracuy Valley. This was soon followed by another rupture with an even greater magnitude of 7.5. Scientists and researchers believe the first quake may could have caused the second.
Many experts agree that the magnitude 7.5 event was considered the main shock, which would make the magnitude 7.2 event a “foreshock.” The reason behind why these two earthquakes took place during such a short period of time is still unclear. However, it is certain that these earthquakes can be defined as doublets, when two major earthquakes are close in strength and location. Although However, last week’s event was quite different from other earthquakes in that region.
Brandon Bishop, a seismologist at Saint Louis University said, “Most doublets don’t occur quite this close together in time,” and “Delays of hours to a few days are much more common.” Scientists believe that the seismic waves that caused the first quake could have violently shaken up another locked-up section of the fissure, leading to the second quake.
“It is very likely that the first triggered the second one,” said Harold Tobin, the director of the Pacific Northwest Seismic Network at the University of Washington.
These quakes are destructive and dangerous because the loose sediment in the Yaracuy Valley could can lead to landslides and temporarily change the state of the soil. This can make the soil making it behave like water, all due to the shaking of the ground.
Even though the magnitude of 7.2 Although a 7.2 magnitude sounds like it is only slightly less than 7.5, the 7.5 quake released almost three times the amount of energy than the 7.2 event. As the fracture traveled through the Yaracuy Valley, it headed east towards the capital city, Caracas, which was directly hit by the path of the quake.
In the past century, there have been seven earthquakes with a magnitude 6 or greater within a 155-mile vicinity of the Wednesday quakes. There are also three major faults mapped out near the twin quakes named El Guayabo Fault, Moron Fault, and Bocono Fault.
In September of 2025, two quakes with magnitudes of 6.2 and 6.3 ruptured just southwest of Wednesday’s quakes in Venezuela, injuring over 110 people and damaging multiple buildings.
According to the U.S. Geological Survey, the area will encounter 3-5 magnitude quakes over the next week. During this period, there is a 24% chance of a magnitude 6 event and a 3% chance of another magnitude 7 quake.
“Normally, aftershocks occur most frequently right after a big one, then tail off exponentially over days to weeks to years,” said Dr. Tobin. This means that Venezuela still has more of this nightmare to encounter, without knowing when or if it will ever finally end.
