Does Mexico have the most earthquakes?

Every year, Mexico records an average of about 30,000 earthquakes, and Guerrero state is hit by about 25% of all national seismic activity. For this reason, the Guerrero seismic gap is something of an anomaly in not experiencing a 7+ magnitude earthquake for more than 110 years.

Why are earthquakes so bad in Mexico City?

Much of Mexico’s volcanic and seismic activity stems from the movement of the North American plate against the Cocos and Pacific plates and it is one of the most active trenches in the world. … While not on or near any fault line like San Francisco or Los Angeles, Mexico City is vulnerable to earthquakes.

Is Mexico prone to natural disasters?
