Volcanology is a geological science that deals with the correlation between volcanic activity and earthquakes, as well as plate tectonics and mountain formation. Geologists that study in this field are called volcanologists. They collect and study data about eruptions to attempt to forecast future occurrences. Volcanologists seek out ore deposits and map out their locations, especially sulfide mineral deposits. The interest in volcanoes dates back to Mt. Vesuvius and its 79 AD eruption, recorded by Pliny the Younger.
