In Colombia the earthquake intensity It is measured with the European Macroseismic Scale (EMS-98), which starts from intensity 2, described as “barely meaning” by very few people at rest; level 3 is classified as “slightly felt”where there may be swinging of some objects.

An earthquake is considered intensity 4 when it is “broadly felt” by many people inside buildings and by few outside. Windows, doors and dishes vibrate. At level 5, “strongly felt”small objects move, there is a swing of doors or windows and slight cracks may be recorded in buildings or houses.

Type 6 intensity implies a “slight 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 a “moderate damage”That is, heavy furniture can move and many buildings have cracks and coatings may fall from the walls.

Finally, at intensities above 7, a “severe damage”: at this point many people have difficulty standing; heavy objects fall; and old, weak structures can collapse.

Colombia is considered a country of high seismic risk because it is located in the Pacific Ring of Firea region that concentrates 75% of the volcanoes that exist in the world and where approximately 80% of the volcanoes occur. strongest tremors worldwide.

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 , Japan, , 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 and this last one that also collides with the Caribbean platewhich 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, which is the second most seismic area in the world.
