USGS releases updated volcanic hazards poster
Posted by Jessica Ball
Just a quick post today, as I’m getting ready for a conference trip next week. For those of you who are familiar with the USGS poster “Geologic Hazards at Volcanoes” – a great graphical depiction of the different types of volcanic activity common at volcanoes – you’re in luck, because there’s a new version out today.

Tee hee …
Apropos of nothing current other than a recent TV broadcast. I was watching a program about the 1944 eruption of Vesuvius which made me realize what I hadn’t remembered knowing and that was that the lava flows that buried some farms and villages originated at the summit which was later “cleaned out” by the explosive phase of the eruption. I got curious and found an article by you about Vesuvius which leads me to ask if at some point when you have time you could explain what would cause this eruption to evolve from effusive to explosive.
