What causes earthquakes?

An earthquake occurs when two blocks of earth slip past each other. This happens along a tectonic plate boundary, especially on the Pacific Ring of Fire. When an earthquake occurs, it’s easy to determine where it was located by measuring its radius. Afterwards, aftershocks follow, lasting days, weeks, and even years. It’s important to know how to detect these aftershocks so you can prepare yourself in case there is another earthquake.

When this happens, the two plates will eventually come into contact. Then, the rough edges of the plates will eventually get stuck while the rest of the plate continues to move. The resulting fault line will release the energy that makes an earthquake occur. The energy released in an earthquake depends on how quickly these plates move past each other. The earthquake will occur when a fault line breaks. The earthquake will cause a massive tsunami if the waves break the ground and destroy buildings and damage infrastructure.
A sudden slip on a fault produces an earthquake. The rocks break loose, releasing energy that travels through the earth’s crust. This movement releases energy in the form of waves. Similar to an earthquake, this energy causes air and rock to vibrate that causes the Earth to shake and the waves created by the movement of rocks are similar. This is how the Earth responds to a sudden rupture.
