They are generally found where tectonic plates come together or separate, but they can also occur in the middle of plates due to volcanic hotspots. A volcanic eruption is when gas and/or lava are released from a volcano—sometimes explosively.
The Global Volcanism Program (GVP) seeks better understanding of all volcanoes through documenting their eruptions--small as well as large--during the past 12,000 years. The range of volcanic behavior is great enough, and volcano lifetimes are long enough, that we must integrate observations of contemporary activity with historical and geological records of the recent past in order to prepare ...
