It is in the West Indies that the seismic hazard is highest, being located at the subduction zone of the North American and South American plates under the Caribbean plate.
The magnitude measures the energy released by an earthquake and allows to evaluate its power. The power of an earthquake is also characterized by the length of the fault that comes into play. The more an earthquake releases energy and the more the fault yields over a long distance, the higher the magnitude.
The intensity measures the effects and damage of the earthquake in a given place: effects observed or felt by man.
An earthquake of very high magnitude can have a zero intensity when it takes place very far from any habitation.
The earthquake itself does not kill, it is the collapse of buildings, badly designed or poorly constructed, which can be accompanied by victims. The best prevention against this risk is therefore to build seismic.
