EXPLAIN THE TYPES OF EARTHQUAKES.​

Answer 1

TYPES OF EARTHQUAKES

Tectonic Earthquakes :-

• The earth’s crust is composed of loose, cracked fragments of land referred to as tectonic plates. These plates are capable of moving slowly and gradually.
• The movement of these plates either towards each other, away from each other, sliding past each other or colliding with each other. A huge tremor occurs when 2 moving tectonic plates slide over one another.

Volcanic Earthquakes :-

1. Volcano-tectonic earthquakes usually happen after a volcanic eruption. During an earthquake, magma erupts from inside the earth’s crust leaving a space behind. The space left after magma eruption must be filled. To fill it, rocks move towards the space resulting in severe earthquakes.
2. Long period of volcanic earthquake takes place after a volcanic eruption. Some days prior to the massive explosion, the magma inside the earth’s crust experiences rapid changes in heat. The change in heat triggers seismic waves, resulting in an earthquake.

Explosion Earthquake :-

• These are caused by nuclear explosions. They are, essentially, man triggered kind of earthquakes and represent the biggest impact of modern-day nuclear war.

Collapse Earthquakes :-

• These kinds of earthquakes are generally smaller and most commonly occur near underground mines. They are sometimes referred to as mine bursts.

Answer 2

Answer:

different types of earthquakes: tectonic, volcanic, and explosion. ... The most common are tectonic earthquakes. These occur when rocks in the earth's crust break due to geological forces created by movement of tectonic plates. Another type,volcanic earthquakes, occur in conjunction with volcanic activity.
