Thousands of aftershocks expected following the earthquake in Venezuela

Venezuela is facing a profound crisis following two major destructive earthquakes recorded with magnitudes between 7,2 and 7,5 that occurred last Wednesday. Search and rescue operations, ongoing to find survivors still trapped under the rubble, are becoming increasingly difficult due to hundreds of aftershocks felt in the region. So far, it has been officially announced that 1.719 people have lost their lives and 3.150 people have been injured; however, experts predict that these numbers will continue to rise in the coming hours and days. The international dimension of the tragedy has been emphasized, noting that 17 İspanyol citizens are among the deceased. The ongoing seismic activity in the region continues to pose a significant security threat for both rescue teams and the local population.

A new tremor with a magnitude of 4,6 has been recorded in the last few hours, very close to the epicenter of the earthquakes. It has been reported that the focal point of this latest aftershock is very close to the cities of Caracas and La Guaira and is located at a depth of only 10 kilometers. Geologist Raúl Pérez from the İspanya Jeolojik ve Maden Enstitüsü (IGME) warned that these aftershocks could be destructive even if they are not as strong as the main shocks. It has been stated that these tremors could have destructive consequences due to their shallow depth and potential interaction with previously damaged buildings and infrastructure facilities. Although the Venezuela Sismolojik Araştırmalar Vakfı (Funvisis) stated that it has detected 355 aftershocks so far, Pérez emphasizes that the actual number is highly likely to be much higher.

Damage to seismic stations in the region caused by the earthquakes has prevented the precise detection of small tremors, particularly those below magnitude 2. Raúl Pérez stated that they expect tremors to continue 'for days and weeks' following the unusual 'double earthquake' the country has experienced. Experts, noting that experiencing thousands of aftershocks is scientifically inevitable following main earthquakes of magnitude 7 ila 7,5, have called on the public to be prepared for a prolonged seismic process. Statistical models from the Amerika Birleşik Devletleri Jeolojik Araştırmalar Kurumu (USGS) also support these predictions. According to these models, the probability of experiencing an aftershock with a magnitude of 5 and above in the coming weeks is 50 percent, and this probability reaches 70 percent over a one-month period.

Experts point out that the first week after an earthquake is typically when the strongest aftershocks occur, making it especially crucial to remain cautious during these days. It has been noted that Venezuela's region has a highly active and complex geological structure, located at the intersection of the Caribbean and South American plates. It is explained that at the Boconó and San Sebastián fault lines in the region, the plates slide horizontally rather than colliding directly, which creates continuous seismic stress. Pérez emphasized that where a destructive earthquake has occurred on these fault lines, it is certain that earthquakes of similar magnitude will occur in the future, but the exact timing cannot be predicted. Furthermore, it has been stated that the fault line in the region has been accumulating energy for the last 120 years, with this tension building up since the last major earthquake in the early 20th century.

While this devastating natural event represents a major tragedy for humanity, it also provides scientists with important opportunities to understand the behavioral patterns of earthquakes. Experts affiliated with the İspanya Ulusal Araştırma Konseyi (CSIC) state that such events will help develop preparedness and risk reduction strategies against potential future earthquakes. Although we cannot exactly predict when and where earthquakes will occur, it is emphasized that thanks to current models, it is possible to estimate the highest probability regions and the magnitude of the strongest aftershock. Researchers from the Madrid Complutense Üniversitesi have stated that the use of early warning systems and new technologies such as mobile phone networks plays a life-saving role in informing the public, especially in regions with weak seismic infrastructure. Thanks to these systems, rapid detection can be made the moment a tremor begins, allowing warnings to be sent to the public, thereby significantly mitigating the potential consequences of the earthquake.
