of the criminal. This essay is aimed towards outlining the theory of plate tectonics, accounting for earthquake and volcanic occurrences in the Caribbean as well as evaluating the measures implemented at the regional level to mitigate the impact of natural disasters. A boundary is a place where tectonic plates touch. This very viscous lava often blocks off vents of volcanoes and when the pressure building up in the vent is eventually released, the top of the volcano can be blown off leaving a huge crater, such as in the 2002 eruption of Mount Etna.

They confirm that the oceanic crust is everywhere younger than about 200,000,000 years and that the stratigraphic age determined by micropaleontology of the overlying oceanic sediments is close to the age of the oceanic crust calculated from the magnetic anomalies. A tectonic plate itself is defined as a rigid segment of the Earths lithosphere that moves separately from those surrounding.
