A Powerful Earthquake Hit Colombia: Here's What Happened and Why It Matters
A powerful earthquake struck western Colombia on the morning of Monday, 10 August 2026. It killed more than 70 people, damaged buildings and homes, and affected at least six airports in the country's coffee-growing and Pacific coastal areas.
The earthquake was measured at 7.4 in magnitude, which is a way of rating how strong an earthquake is. Anything above 7.0 is considered a major earthquake capable of causing serious damage. The center of the quake, called the epicenter, was about 5 km east of a small town called San José del Palcar, in a region of Colombia known as Chocó. This was reported by both the U.S. Geological Survey and Colombia's own geological service. The shaking was felt as far away as neighbouring Venezuela. The Guardian
The worst damage hit Colombia's western mountain region. Authorities reported 27 deaths in the Valle del Cauca area, where the mayor of its largest city, Cali, said at least 20 buildings had collapsed and people were trapped inside. In the city of Pereira, 18 deaths were reported. The newspaper El Espectador, citing government officials, said at least 72 people were killed across the country, 40 of them in the Pereira area. At least two people died in the city of Manizales. The Guardian
The cities hit hardest, Pereira, Manizales, and Cali, all sit in a valley along Colombia's western mountains. This area is known for growing coffee and has a history of earthquakes. The quality of buildings there varies a lot, so while some can survive strong shaking, others cannot.
The mayor of Manizales, Jorge Eduardo Rojas Giraldo, said at least 12 buildings and 20 homes were partly or completely destroyed. He warned people to stay out of damaged buildings and to be ready for aftershocks, which are smaller earthquakes that often follow a big one. The city's cathedral was also damaged. In Quibdó, the capital of Chocó, the governor reported injuries and severe damage to buildings. The Guardian
Colombian aviation authorities said six airports were damaged: in Pereira, Manizales, Quibdó, Cartago, Armenia, and Buenaventura. These airports are spread across about 250 km, making it harder to fly in emergency help. Buenaventura is also Colombia's main port on the Pacific coast, so damage to its airport could affect the flow of goods into the region.
Colombia's new president, Abelardo de la Espriella, had only taken office on Friday, 8 August, just two days before the earthquake. He flew to Bogotá, the capital, to lead the government's response. Because his administration was so new, key government positions and emergency plans were not yet fully in place. U.S. Secretary of State Marco Rubio said the United States was watching the situation closely and was ready to help. The Guardian
Just seven weeks earlier, on 24 June 2026, two earthquakes hit Venezuela's northern coast and killed more than 6,000 people. That disaster would have already put emergency agencies in the region on high alert. The Colombia earthquake, while far less deadly, adds pressure to those same relief networks.
The two events happened on different parts of the Earth's crust. To understand why, it helps to picture the ground beneath us not as one solid shell but as a set of giant rocky puzzle pieces called tectonic plates. These plates are always slowly moving. When they bump, grind, or slide past each other, energy builds up. When that energy is suddenly released, it causes an earthquake.
The broader context here is that western Colombia sits above one of the most earthquake-prone areas in the Americas. One plate, called the Nazca plate, is slowly sliding underneath another, the South American plate, right beneath Colombia's western mountains. That process has produced powerful earthquakes throughout history. A 7.4-magnitude quake like this one can seriously damage well-built structures and destroy poorly built ones, especially in cities where building standards are mixed.
The different death counts reported by various officials and news outlets show that the situation is still unfolding. In major earthquakes, the number of confirmed deaths usually rises over the first day or two as rescuers clear rubble and reach remote areas. Chocó, where the earthquake was centered, is one of Colombia's most isolated and hard-to-reach regions, so getting a full picture of the damage there will likely take longer than in the more accessible mountain cities.
