What types of movement in Earths crust causes earthquakes?

Answer 1

Earthquakes are primarily caused by the movement of tectonic plates in the Earth's crust. This movement can occur along faults, which are fractures in the Earth's crust where rocks on either side have moved relative to each other. The most common types of fault movement that cause earthquakes are strike-slip faults, where rocks move horizontally past each other, and dip-slip faults, where rocks move vertically relative to each other. The stress that builds up along these faults eventually exceeds the strength of the rocks, leading to sudden release of energy in the form of an earthquake.

Answer 2

Earthquakes are typically caused by the movement of tectonic plates along faults in the Earth's crust. This movement can result in stress build-up in the rocks along a fault line, eventually being released as seismic waves during an earthquake. Other causes of earthquakes include volcanic activity, landslides, and human activities like mining or reservoir-induced seismicity.

Answer 3

When the two different kinds of plates collide, a part of the world starts to shake exactly like an earthquake.
