What type of plate boundary caused the 1985 Mexico City earthquake?

Exactly 32 years ago, on 19 September 1985, a collision between the Cocos and North American plates caused a magnitude 8.0 earthquake that devastated Mexico City and killed 10,000 people.

Is Mexico City earthquake prone?

That means the people of Mexico City can feel nearly every major quake in the region, even if the epicenter is hundreds of miles away. This effect was notable during a magnitude 8.1 earthquake in 1985, which caused intense damage throughout Mexico City despite the fact that its epicenter was more than 200 miles away.

Is Mexico tectonically active?

Situated atop three of the large tectonic plates that constitute the earth’s surface, Mexico is one of the most seismologically active regions on earth. The motion of these plates causes earthquakes and volcanic activity. Most of the Mexican landmass rests on the westward moving North American plate.

Why is Mexico at the boundary of three tectonic plates?

Mexico sits at the boundary of three tectonic plates: the Cocos plate, the North American plate, and the Pacific plate. Mexico City is especially prone to severe damage because of the ground it sits on — an ancient lakebed that quivers like jello, Bellini says. When earthquake waves pass through it, it jiggles, magnifying the vibrations.

Where is Mexico located on the American Plate?

Most of Mexico is located at the bottom of the large American plate. In the south part it converges with the plate of the Caribbean. This plate covers both the Caribbean Sea and most of the Antilles, including much of Cuba, a part of South America and almost all of Central America.

Where did the earthquake in Mexico take place?

The country sits at the boundary of three pieces of the Earth’s crust that fit together like a jigsaw puzzle — called tectonic plates. Today’s quake originated on a fault within the Cocos plate, which is on Mexico’s western edge.

Where does the Caribbean Plate converge with Mexico?

In the south part it converges with the plate of the Caribbean. This plate covers both the Caribbean Sea and most of the Antilles, including much of Cuba, a part of South America and almost all of Central America. From Mexico, the Caribbean plate contains south of Chiapas.
