occur along the edge of the oceanic and continental plates 81% of earthquakes occur at the rim of the Pacific Ocean. Earthquakes accompany elevation changes and mountains and changes in the oceans trenches

when rock underground suddenly breaks along a fault this sudden release of energy causes the seismic waves that make the ground shake when two blocks of rock or two blocks run against each other they create a powerful energy that radiates the earth surface

a study in 2013 says earthquakes could be contributing towards climate change, they lead to the release of Methane that is held within pockets of the earth, which are located at sub sea levels and can be released by the shifting of tectonic plates.
