What produces the heat in the centre of the earth?

The core produces heat in the center of the earth

There are three main sources of heat in the deep earth: 1, heat from when the planet formed and accreted, which has not yet been lost. 2 frictional heating, caused by denser core material sinking to the center of the planet, and 3:heat from the decay of radioactive elements.

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
