BOGOTÁ, Colombia. At least 111 people have been killed and 87 injured after a powerful 7.4-magnitude earthquake struck western Colombia on Monday, causing buildings to collapse, homes to be destroyed and residents to become trapped beneath rubble, officials said.

President Abelardo de la Espriella declared a national disaster as emergency crews responded to widespread destruction reported across several cities and communities.

The U.S. Geological Survey said the earthquake was centered about 5 kilometers east of San José del Palmar, Colombia.

Some of the most severe damage was reported in Cali and Pereira. Officials said dozens of people were killed in the departments surrounding the two cities as rescue teams searched damaged buildings for survivors.

At least 61 buildings have collapsed, while more than 1,600 homes have been damaged or destroyed, according to the president. Health centers, community facilities and roads were also among the infrastructure damaged by the quake.

In Cali, at least 20 buildings collapsed, according to the city’s mayor. Rescue workers were conducting an operation at one damaged building where at least 15 people were believed to be trapped.

Authorities in the department of Chocó also reported injuries and “severe damage” to buildings in Quibdó, the department’s capital.

The earthquake also disrupted air travel, with seven airports suspending operations in Armenia, Cali, Manizales, Pereira, Quibdó, Buenaventura and Cartago.

There were no immediate reports of collapsed buildings in Bogotá, officials said.

The earthquake, which struck Monday morning, was the strongest recorded in Colombia in a decade, according to the Colombian Geological Survey. The shaking was felt throughout much of Colombia as well as in neighboring Venezuela, Ecuador and Panama.

In a video posted on social media, the Colombian president said he was traveling to Bogotá to “focus on addressing the emergency facing our country”. He also convened a unified command post to coordinate the government’s response in affected areas, including the region known as the Coffee-Growers’ Axis.

The United States said it was closely watching the situation. Secretary of State Marco Rubio said the Trump administration is “closely monitoring” the earthquake and stands “ready” to support the people of Colombia.
