TREMOR IN MEXICO | Why are there earthquakes frequently?

The World Health Organization (WHO) reports that an earthquake can be defined as an earth tremor that is caused by waves that are propagated through the earth’s crust and below it. The Earth is made up of four main layers: the crust, the mantle, the liquid outer core and the solid inner core. Earthquakes take place in the lithosphere, which is located in the outermost part of the Earth, that is, the upper part of the liquid mantle and the earth’s crust.
