What would occur if tectonic plates move quicker?
When plates smash into each other at greater speeds, more of the crust at the accident websites ends up being fragile, which makes the area more susceptible to big quakes.
Earthquakes happen on faults— strike-slip earthquakes happen on strike-slip faults, regular earthquakes take place on regular faults, and thrust earthquakes take place on reverse or thrust faults. When an earthquake happens on among these faults, the rock on one side of the fault slips with regard to the other.
Earthquakes happen along geological fault, fractures in Earth’s crust where tectonic plates satisfy. They happen where plates are subducting, spreading out, slipping, or clashing. As the plates grind together, they get stuck and pressure develops. The pressure in between the plates is so fantastic that they break loose.

How do faults form?
A fault is formed in the Earth’s crust as a fragile reaction to tension. Usually, the motion of the tectonic plates supplies the tension, and rocks at the surface area break in action to this. Faults have no specific length scale.
