How do you define Volcanology?

Volcanology (also spelled vulcanology) is the study of volcanoes, lava, magma and related geological phenomena. A volcanologist (also spelled vulcanologist) is a person who studies in this field. The term volcanology is derived from the Latin word vulcan, the Roman god of fire. Volcanologists frequently visit volcanoes, especially active ones, to observe volcanic eruptions, collect eruptive products including tephra (such as ash or pumice), rock and lava samples. One major focus of enquiry is the prediction of eruptions; there is currently no accurate way to do this, but predicting eruptions, like predicting earthquakes, could save a lot of lives. A volcanolgist (also spelled vulcanologist) studies the formations of volcanoes and the current and historic eruptions of them.
