Answer 2

★ Earthquake :- ★

➥ Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth's rocks. The major fault lines of the world are located at the fringes of the huge tectonic plates that make up Earth's crust.

✦ Strong 6 - 6.9

✦ Moderate 5 - 5.9

✦ Light 4 - 4.9

★ Faults :- ★

➥ Earthquakes occur on faults - strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.

★ Statistics :- ★

➥ It is estimated that there are 500,000 detectable earthquakes in the world each year. 100,000 of those can be felt, and 100 of them cause damage.
