While Mexico’s position along major tectonic fault lines makes it a hotbed of seismic activity, the frequency of these powerful earthquakes begs the question: Are these quakes happening more often? [The 10 Biggest Earthquakes in History]
Not likely, said Gavin Hayes, a research geophysicist at the U.S. Geological Survey’s National Earthquake Information Center.
“Mexico is very prone to earthquakes,” he
