A powerful 6.6-magnitude earthquake struck Colombia on Monday, according to the nation's geological service, with the tremors felt across a wide region including the capital Bogotá.

The Colombian geological service measured the quake at 6.6 on the Richter scale, while the United States Geological Survey (USGS) reported a higher magnitude of 7.4. Initial reports did not immediately specify casualties or significant structural damage, but the force of the tremor was widely noted.

The seismic event occurred at a depth of approximately 161 kilometres, with its epicentre located near the town of Los Santos in the Santander department, a region known for its frequent seismic activity. Residents from Medellín to Cali reported feeling prolonged shaking.

Seismic Activity Common in Andean Nation

Colombia sits within the Pacific Ring of Fire, a horseshoe-shaped area known for its intense seismic and volcanic activity. Earthquakes are a regular occurrence in the country, though quakes of this magnitude are less frequent.

Past significant seismic events have led to infrastructure damage and, in some cases, loss of life. Authorities are currently assessing the impact across the affected departments and are expected to provide further updates as information becomes available.

Authorities Assess Damage and Risk

Emergency services have begun initial sweeps of affected areas to determine the extent of any damage and identify communities in need of assistance. Residents have been urged to remain vigilant for potential aftershocks, which can follow a major tremor.

The National Unit for Disaster Risk Management (UNGRD) is coordinating the response, focusing on critical infrastructure and densely populated urban centres. Telecommunications networks were reportedly stable in most areas following the quake.
