This week’s devastating earthquake in Colombia has prompted concern in Mexico, where some people have questioned whether the disaster could foreshadow a comparable seismic threat. Although both countries are situated along the Pacific Ring of Fire — a geologically volatile region associated with recurrent earthquakes — specialists emphasize that Colombia’s 7.4-magnitude tremor does not heighten the probability of a similar event in Mexico.
The Colombian Geological Service described the earthquake as the country’s most powerful of the 21st century. By Tuesday, the death toll had surpassed 200 as emergency personnel continued recovery operations and searched through damaged communities for survivors.
Mexico’s President Claudia Sheinbaum offered assistance to Colombia, saying her government is awaiting a formal request before deploying aid. According to Telesur, the Venezuelan news outlet, Mexico is prepared to dispatch a 255-member military search-and-rescue contingent, accompanied by satellite telephones, radios, generators, substantial food provisions and medical supplies.
Why an earthquake in Colombia doesn’t mean Mexico will have one
Mexico and Colombia both sit within the Pacific Ring of Fire, an immense zone encircling the Pacific Ocean that is distinguished by intense seismic and volcanic activity. The region produces roughly 90% of the world’s earthquakes and contains three-fourths of its active volcanoes. Nevertheless, occupying the same tectonically active belt does not mean that an earthquake in one country can precipitate another in a neighboring nation.
The earthquake in Colombia was primarily caused by the interaction between the Nazca and South American plates. In contrast, Mexico’s seismic activity is driven by the Cocos Plate pushing beneath the North American Plate and the Rivera Plate contributing in the west.
While seismic waves from a major earthquake can sometimes cause disturbances far away, this does not allow scientists to predict a large earthquake in Mexico. The movement of tectonic plates is a constant process, releasing stress along various faults at different times and depths.
