At least 18 aftershocks were recorded by the Colombian Geological Service in the hours following the main shock . The USGS reported maximum Modified Mercalli Intensity of VIII (Severe) in parts of Quindío and Caldas, and VII (Very Strong) in Manizales and Cartago
.
The death toll rose rapidly as reports came in from remote areas. President Abelardo de la Espriella confirmed at least 111 dead late on August 10 . The Wikipedia tally reached at least 132 killed, with more than 620 people injured and over 3,000 reported missing
. Early casualty counts varied from 20 to 111 as information reached authorities from isolated communities
.
The shaking was felt across most of Colombia, including Bogotá, Cali, Medellín, and Pereira, and was detected in neighboring Ecuador and Panama .
The hardest-hit department was Risaralda, where at least 42 people died, concentrated in the city of Pereira . Heavy damage also occurred in Cali and across the Chocó department
. In Manizales, two people were killed
.
Approximately 1,600 buildings were damaged, with at least 61 completely collapsed . Dozens of buildings collapsed in Cali and Pereira, trapping people under debris
. Hospitals and other critical infrastructure were also damaged
.
Colombia's civil aviation authority suspended operations at six airports due to structural damage, including airports serving the affected western regions . All flights at these airports were halted
.
President Abelardo de la Espriella, who had been inaugurated just the previous week, declared a state of national disaster to facilitate rescue efforts and traveled to Pereira and San José del Palmar to oversee the recovery personally .
The U.S. government responded swiftly to the disaster:
The Colombian Geological Service (SGC) called this the strongest earthquake recorded in the country in the last decade . The previous large event was a magnitude 5.8 quake near Cartago in 2016, which was far less severe.
On a global scale, the 7.4 magnitude is comparable to other notable intermediate-depth South American earthquakes, but the death toll of over 100 places it among the deadliest quakes in Colombia since the 1999 Armenia earthquake (M 6.2, ~1,200 deaths) and the 1983 Popayán earthquake (M 5.5, ~300 deaths). The large number of missing persons (3,000+) may further raise the final toll as rescue operations continued in remote Chocó communities .
