What caused the 2017 Mexico City earthquake?

Earthquakes are common in Mexico because of most of the land mass being on the North American plate and the Ocean floor being on the Coscos plate and so when the more dense ocean floor plate goes up and hits the North American plate it goes up under the more finer granite part of the North American plate and if you …
What caused the earthquake in Mexico?
Monday's earthquake was the result of the “interaction of the Cocos plate with the North America plate”, which also caused the 1985 earthquake, Perez-Campos said. Five plates – the North America, the Pacific, the Rivera, the Caribbean and the Cocos – all run under Mexican territory.
What type of plate boundary caused the 2017 Mexico earthquake?
subduction zoneThis collision zone is called a subduction zone, and in this case the Cocos oceanic plate is being shoved beneath the North America plate of which Mexico is a part. The subduction zone is a large fault zone inclined beneath Mexico at an angle of about 15°, starting in a deep northwest-trending offshore oceanic trench.

How do earthquakes happen?
Earthquake happen when two tectonic plates rub against each other. Remember our Earth is not a dead planet, so movement is small but sometimes energy is released rapidly and causes sudden earth movements. Places along the edges of tectonic plates are prone to earthquakes every so many years and have tremors much more often.
Why do earthquakes occur?
Earthquakes happen because of tectonic plate shifts. Central Mexico is in between three Sierra Madre mountain ranges. These mountains exist because the tectonic plates have pushed against each other for so long.

What happens when a plate bends?
When the plate bends downward, some of the rocks in the plate break. Think of a sturdy piece of wood. Flexed lightly, it bends. But when the flexing becomes too strong, it will splinter violently. This is what causes “bending” earthquakes like Mexico City’s.

This “fabric” was created about 8 million years ago, when the rocks first formed – way before tectonic plates collided to give Mexico its subduction zone.
