EARTHQUAKE-EXTERNAL

The earthquake occurs due to the rubbing of one rock over the another rock.

The earthquake is off different speed, direction, strength,etc.

It consists of several layers and each layer moves in different way.

Primary layer flows in length wise.

Secondary layer flows cross wise.

Next layer flows around that particular area.

This can be measured using ritcher scale.

Actually in that instrument a chart be present.
