Causes of Earthquakes
Volcanoes
Plate Tectonics
Earthquakes can be caused by pressure which is created by either volcano or mankind.
Man-made Activities
pressure exerted by hot gases realized during volcanic erruption
example : Krakatoa volcanic erruption
the heat within the planet causes movement in tectonic plates
When we human perform mining the drill goes deeper and deeper and it reaches the earth's surface, they collect resources from it but the holes dug in there can cause instability and can cause earthquake's
Folding and Faulting
Example : pacific ring
Folding and faulting in the earth's crust are caused by internal horizontal and vertical movements caused by compressional and tensional pressures. Rocks in the crust are displaced as a result of this.
Example: 1906 San Andreas Fault of California
nuclear explosion
blasting of rocks
construction of huge dams
