A volcanic belt is a district of volcanoes, located in a certain area. In shrinking size there are belts, clusters, chains and volcanic fields. Volcanoes in Mexico and in western North America are mostly in volcanic belts, sush as the Trans-Mexican volcanic belt that extends 900 km from west to east across central-southern Mexico and the Stikine Volcanic Belt in western Canada. Volcanic belts can be formed by subduction zones, which is when one tectonic plate is sinking under an other tectonic plate, or by hotspots, a location on the Earth's surface that has experienced active volcanism for a long period of time.
