What is an Earthquake and What Causes Them to Happen?
An earthquake is a forceful shaking of Earth’s surface which is caused by movements in the Earth’s outmost layer.
The Earth’s appearance is like a solid place on its surface but extremely energetic below.
In the surface of Earth, there are 4 layers which are commonly known as Crust, Mantle, Outer Core, and Inner Core.
Tectonic plates are there through the solid crust and a mantle.
These Tectonic plates slowly move the layers below and cause pressure on Earth’s crust.
If the stresses get too large, it leads to cracks called faults and when these tectonic plates move, it also causes movement and unexpected slip on a fault leading to the deadliest earthquake.
This movement is measured in magnitude which was first recognized by Charles Richter. In fact, there is no theoretical limit to the earthquake magnitude, although it is estimated that a magnitude 11 would divide the Earth in two.
