@SofiaSantiago,
I know a few vulcanologists at our USGS. Usually theres a strong recruitment program because you spend a lotta time in the field at first. Ithink that vulcanologists or geophysicists who havent paid their dues in the field and only elect to play with models are WUSSIES!!.
(Just kidding)
If I was in a grad program under some vulcanology program, Id make sure to get a strong additional course level of economic geo (such as hydrothermal deposition ). Id want to be a super experimenter in Pegmatites and Peridotites.
Im pretty much retired except for a few mining projects and I gotta say Id do it all again. Theres a lot of places youll see that you didnt even know existed, and you have enough free time and cash to do side exploration.
Pinatubo was erupting but NO i was many miles out of range of all the Peleian Clouds (Qlthough many of the chopper pilots had their busses full of geologists who wanted to fly around the caldera before they declared it off limits and threatened pilots who were even thinking of taking geoadventurists around the site.
My pix are of beautiful sunets and volcano thunderstorms at dusk. The colors and the flashes were outstanding even from 20 miles away
