 Vulcanology, vulcanology also spelled vulcanology is the study of vulcanos, lava, magma, and related geological, geophysical and geochemical phenomena. The term vulcanology is derived from the Latin word Vulcan. Vulcan was the ancient Roman god of fire. A vulcanologist is a geologist who studies the eruptive activity and formation of vulcanos, and their current and historic eruptions. Vulcanologists frequently visit vulcanos, especially active ones. To observe volcanic eruptions, collect eruptive products including tether as such as ash or pumice rock and live-it samples. One major focus of inquiry is the prediction of eruptions. There is currently no accurate way to do this, but predicting eruptions, like predicting earthquakes, could save many lives.
