Mexico has suffered far more powerful earthquakes recently; a 7.1 magnitude one that hit on Tuesday, killing at least 295 people, as well as the 8.1 magnitude quake in the southern state of Chiapas earlier in September.
Mexico lies at the meeting point of three major tectonic plates, and it is therefore prone to multiple earthquakes within a short time, as have occurred in recent weeks.
