The earthquake began at 10:03 (local time) and had a depth of 5 kilometers, with a latitude of 5.060404778 and a longitude of -73.14756775.
In Colombia, the intensity of earthquakes is measured with the European Macroseismic Scale (EMS-98), which starts at intensity 2, described as “barely felt” by very few people at rest; Level 3 is classified as “slightly felt”, where there may be swaying of some objects.

An earthquake is considered intensity 4 when it is “widely felt” by many people inside buildings and by few outside. Windows, doors and dishes vibrate. At level 5, “strongly felt”, small objects move, doors or windows swing, and slight cracks may be detected in buildings or houses.
Type 6 intensity implies “mild damage”, in this range some people can lose their balance; Some objects fall and many buildings have minor damage. Level 7 occurs when there is “moderate damage”, that is, heavy furniture becomes displaced and many buildings have cracks and coatings may fall from the walls.

Finally, at intensities above 7 “severe damage” occurs: at this point many people have difficulty standing; heavy objects fall; and old, weak structures can collapse.
Approximately 80% of the strongest earthquakes in the world occur in this region. (Infobae)
Colombia is considered a country with high seismic risk because it is located in the Pacific Ring of Fire, an area that concentrates 75% of the volcanoes that exist in the world and where approximately 80% of the strongest earthquakes occur. global level.
Also known as the Pacific Ring of Fire, it is made up of the mountainous area of western Argentina, Chile, Peru, Ecuador, Colombia, Panama, Costa Rica, Nicaragua, El Salvador, Honduras, Guatemala, Mexico, the United States and Canada, to then turn around the Aleutian Islands and go down the coasts and islands of Russia, Japan, Taiwan, the Philippines, Indonesia, Malaysia, East Timor, Brunei, Singapore, Papua New Guinea, Solomon Islands, Tonga, Tuvalu and New Zealand.
In the specific case of Colombia, the country is located in two important subduction areas, since on the one hand it has the Nazca plate with the South American plate and the latter also collides with the Caribbean plate, which causes it to tremble constantly. .
Given this situation, the departments of Nariño, Chocó, Caldas and Santander are the places where it trembles the most; In the latter is the municipality of Los Santos, considered the second most seismic area in the world.
Ecuador-Colombia of 1868
Two tremors were recorded in the border area of Ecuador and Colombia on August 15 and 16, 1868, with magnitudes of 6.3 and 6.7, the latter being the most deadly with a duration of almost a minute of movement.
The first of them was recorded in the towns of El Ángel and La Concepción; while the second earthquake left the Ecuadorian city of Ibarra completely devastated. It is believed that this movement caused around 70 thousand victims, counting deaths and injuries in both countries.
Cúcuta earthquake of 1875
Also known as the Andes Earthquake, this tremor originated on May 18, 1875 and had a magnitude of between 7.5 and 8.5 in Cúcuta, although it also caused damage in the neighboring Venezuelan state of Táchira.
Although some claim that the number of victims of this earthquake reached 3,000, at least in the affected area of Colombia only 461 bodies were found. From this earthquake, hot springs also emerged from the sites today known as “Agua Hedionda”, “El Tampaco” and “Aguas Calientes”.

1906 earthquake and tsunami
An 8.8 magnitude earthquake struck the province of Esmeralda in Ecuador, bordering Colombia, on January 31. This movement generated a tsunami that left 1,500 dead. According to information from the SGC, the waves reached five meters high and left the Colombian region of Tumaco underwater.
1994 Páez earthquake
The earthquake originated in the foothills of the Central Cordillera of the Cauca Andes, in southwestern Colombia, on June 6, 1994. It had a magnitude of 6.4 and left around 800 people dead, mainly the inhabitants of the communities close to the Páez River. This is considered the second deadliest in the country’s history.
Coffee Axis of 1999
Considered the worst earthquake in the country’s recent history, this earthquake affected the departments of Quindío and Risaralda in Colombia, leaving more than a thousand people dead.
The earthquake occurred on January 25, 1999 and had a magnitude of 6.2. Several hospitals were affected and resources to deal with the emergency were limited. The earthquake left four thousand people injured and nearly 500 missing.
Around eight thousand coffee farms were completely or partially destroyed, and 13 thousand structures of many types of companies and industries were affected.
