The Guerrero seismic gap is a segment of the subduction zone between the Cocos Plate and North American Plate where no major earthquake has been recorded in over 100 years. This geological anomaly is one of the most studied by Mexican and U.S. seismologists.
Historically, major earthquakes in this region have occurred approximately every 100-140 years. The last major event was in 1911, over 110 years ago. This lack of activity suggests an accumulation of tectonic stress that could be released as a magnitude 7.5-8.0 earthquake at any time.
The state of Guerrero and adjacent zones like Oaxaca, Morelos, and Michoacรกn are particularly at risk. An earthquake of this magnitude could severely affect Mexico City, located over 300 km away, due to the amplification effect described earlier.
Seismology experts emphasize that the risk is not a matter of "if" but "when". Preparedness and rapid response plans are essential throughout the region.
