Deadliest Earthquakes In The History Of The World

Deadliest Earthquakes In The History Of The World

Earthquakes occur when the planetary tectonic plates diverge or converge on each other releasing energy in the Earth’s crust, this energy creates seismic waves which in turn shake the surface of the Earth. Earthquakes have continued to play a vital role in shaping up our planet, they have also caused extreme destruction.


Whenever an earthquake occurs, it releases three types of waves, P(primary) waves, S(secondary) waves and surface waves which cause the actual destruction on the surface of Earth. This is due to the fact that surface waves travel across the surface of the Earth creating a ripple effect.


Here are the top ten most deadliest earthquakes in the history of the world.
