So this source places the eruption of Vesuvius during 79AD to be as powerful as 100,000 times that as the bombs dropped on hiroshima and nagasaki. But this number seems to be way larger than the numbers reported for other similar volcanoes (for example mt St Helens is estimated at 26 megatons) so where does this number come from?

Is it possible that a volcano can make a phreatic eruption, even if no activity can be detected by the most sensitive instruments?

I want to climb to the top of a volcano in the Philippines. It's Mt. Hibok-Hibok and its eruption was in the 1958. From its last eruption, the volcanoes remain silent and no seismic activity is detected since then. Hotsprings around the volcano even cooled down over the past decades.

Probability of magmatic eruption can be detected. But what about phreatic eruptions (steam-driven explosions)?

I'm asking this because the volcano attracts tourists. I do not want to be surprised that the volcano will awaken someday while we are hiking on its crater.

Hi fellow volcanologists! I have recently graduated from The University of Manchester with a Master's Degree in Earth Science, specialising in Volcanology & Geology. I absolutely loved studying the field of volcanology, completing multiple volcanology-based research projects throughout my degree which have armed me with a plethora of skills.

I am now in a position where I would like to explore all options that are available to me in order to continue my journey in the Volcanology field. I know the obvious option is undertaking a PhD here in the UK, and I will be applying for these when they become available, but I also wanted to hear about any options that you guys know of, for example over in the US.

Look forward to hearing from you guys!

I am Currently a sixth-form student (U.K.) and I’ve always wanted to go into Volcanology but I hate school and do not want to go into university. I was wondering if there was another way that didn’t require luck or if I would have to go through university

I’m 3 days into a PhD in volcanology in the U.K., at the same university as I did my undergrad degree. Does anybody have any great tips or bits of advice on how to help your PhD go as smoothly as possible? I don’t handle stress particularly well, so if there’s any steps I can take now to prevent stress later down the road, it would be much appreciated! I of course know my PhD will be stressful at times, but I’m really excited to get into it :)

Thanks!

Ok, first off, I know science is metric :) But I am working on a report and need to convert lava flows to imperial measurements and I am lousy at math.

Two things in particular:

+want to convert 15 million cubic meters. Calculator tells me this is 3.2 billion gallons.

+want to convert 60 cubic meters. Calculator tells me this is 13,000 gallons.

Sound right? or...not?

Lastly, does it make sense to say x number of cubic meters of lava is the same as y number of gallons of the stuff?

What were volcanos like before the continents broke apart? Were they scattered all over the world like they are now or did they not exist back then or did they travel with each continent when they drifted apart?

An article published by the BBC Science Focus. Headline is kinda alarmist, but thoughts on the content? https://www.sciencefocus.com/planet-earth/earths-supervolcanoes-are-waking-up-heres-what-that-means-for-the-planet

Does anyone know of any good work experience programmes with regards to volcanology?

Also, does anyone know the entry salary for volcanology and then the salary at more senior levels?

We were landing in Nicaragua recently and I saw this peaking above the clouds. I know volcanoes are all around here and wasn't sure if this was a volcano. Any feedback greatly appreciated. Thanks!

74,000 years ago, the Toba supervolcano eruption caused a global volcanic winter that almost caused the extinction of early humans.

For those that have time and the energy, is there a event, eg. a asteroid strike off the oregon cost, that could chain react the Pacific rim volcanoes here in the PNW? I was reading about how Smith Rock was actually formed from Magma from Yellowstone so the idea came to me that with a large enough a event it could cause multiple eruptions. Thoughts?

edit, not trying to be a sensationalist but just doing research and asking for the knowledge to be imparted upon me!
