How many years of college are needed to get a degree as volcanologist?

To become a volcanologist, you'll typically need at least a four-year Bachelor's degree, followed by a further two-year Master's degree, and often a PhD (which usually takes another 4-7 years). While a Bachelor's degree can get you into some entry-level positions related to geology, a Master's or PhD is generally required for independent research and most volcanology-specific jobs. So, the total time commitment is usually 8-11 years of college and university study.
