A deadly cocktail: why the double earthquake destroyed so many buildings in Venezuela

The article discusses the devastating impact of two earthquakes measuring 7.2 and 7.5 on Venezuela, resulting in over 6,300 deaths and thousands displaced. Experts attribute the destruction to unstable soil, seismic activity along tectonic plate boundaries, and poor construction practices. In Catia La Mar, residents like Jennire García live in temporary shelters while their homes remain uninhabitable due to structural risks. The region, particularly La Guaira, has historically faced geological challenges, including a deadly landslide in 1999. Engineers highlight that the combination of weak soils and inadequate building standards created a 'perfect storm' during the quakes, amplifying the seismic signals and leading to widespread collapse. Official data indicates that over 22,000 homes were severely damaged or deemed high-risk, representing 40% of evaluated structures. Despite updated seismic regulations since 1967, ongoing issues suggest persistent gaps in construction safety.

A powerful earthquake measuring 7.4 struck Colombia early Monday morning, shaking much of the country and neighboring nations. The quake occurred at 7:34 a.m., with its epicenter near San José del Palmar in the northern department of Chocó. Despite originating at a depth of approximately 100 kilometers, the tremor was felt widely across Colombia and beyond, causing extensive damage and leaving at least 170 people dead and over 700 injured. Dozens of buildings collapsed, and many more sustained serious structural harm. The event has reignited concerns about seismic activity in a region already prone to frequent earthquakes. The earthquake followed another major tremor in nearby Venezuela just six weeks earlier, which measured 7.5 and struck on June 24. While both quakes had similar magnitudes, geological experts emphasize they were distinct events caused by different tectonic processes. In Venezuela, the Caribbean Plate moved horizontally eastward, creating friction with the South American Plate and resulting in long surface ruptures. This led to more severe destruction due to the shallower depth, only 15 kilometers, and higher population density in affected areas. In contrast, the Colombian quake resulted from the subduction of the Nazca Plate beneath the South American Plate, occurring at a greater depth of 100 kilometers, which reduced the intensity of ground shaking at the surface. Colombia's location along a complex tectonic boundary contributes to its high level of seismic activity. According to Freddy Tovar, coordinator of Colombia’s national seismic network, the country sits at the intersection of three major tectonic plates, the Nazca, South American, and Caribbean, creating conditions for frequent earthquakes. The National Geological Service of Colombia records around 2,500 seismic events per month, though most are too small to be noticed. These quakes occur as accumulated energy from tectonic stress causes sudden rock fractures, releasing energy in the form of seismic waves. Experts note that while the Colombian earthquake was less destructive than the Venezuelan one, its impact was still significant given the region’s vulnerability. The deeper focus of the Colombian quake meant that the seismic waves reached the surface with less force compared to the shallow Venezuelan event. However, even this reduced intensity was enough to cause widespread damage in areas where infrastructure was not built to withstand such forces. Geological differences between the two quakes highlight how tectonic interactions vary across regions. In Venezuela, the movement of the Caribbean Plate against the South American Plate created long surface ruptures, leading to more extensive ground deformation. In Colombia, the subduction process of the Nazca Plate under the South American Plate generated a different pattern of energy release, affecting the type and extent of damage observed. Authorities continue to assess the situation in Colombia, focusing on rescue operations and damage assessments. Emergency services have been deployed to affected areas, and officials warn that additional aftershocks could occur. Seismologists suggest that while the risk of large secondary quakes is relatively low, smaller tremors remain possible in the coming days and weeks. The focus now shifts to recovery efforts, including rebuilding damaged infrastructure and ensuring public safety in regions previously unaffected by such intense seismic activity.

A geologist explained in detail why the earthquake occurred in Colombia and if it can happen again

A strong earthquake struck a wide region of Colombia on Monday, being felt in several cities in the center and southwest of the country, including Bogotá, where residents of buildings and residential complexes evacuated preemptively after alarms were activated. Geologist Eduardo Malagnino explained that the quake occurred due to the subduction of the oceanic plate beneath the South American plate, which eventually caused a rupture along a fault line. He clarified that the depth at which the rupture begins is called the hypocenter, while the projection of this point onto the Earth's surface is known as the epicenter. The specialist also noted that the recent earthquake in Colombia differs from the recent seismic activity in Venezuela, as they involve different tectonic plates. The Colombian earthquake resulted in 22 deaths so far.

Earthquakes in Colombia and Venezuela: why it happened, what is the risk of aftershocks and if it can affect other countries

Un terremoto de magnitud 7,4 ocurrido en Colombia el 10 de agosto causó al menos 170 muertes y más de 700 heridos, con graves daños en edificios y amplia percepción en el país y vecinos. El evento resalta la actividad sísmica constante en Colombia debido a su ubicación en una zona tectónica compleja donde interactúan varias placas. Expertos explican que el sismo fue de profundidad intermedia y liberó mucha energía, afectando ampliamente. Aunque hubo un terremoto similar en Venezuela una semana antes, los especialistas indican que estos eventos no están relacionados y tienen causas tectónicas distintas.
