Active Volcanoes

They erupt frequently and are mostly located in the Pacific Ring of Fire, which includes New Zealand, Southeast Asia, Japan and the western coast of the Americas.
About 90% of all earthquakes worldwide strike within this region.
Volcanic activity is linked to the movement and collision of tectonic plates.
Examples include Kilauea in Hawaii and Santa Maria in Guatemala.
