I get a fairly steady stream of emails from Eruptions readers, some of which are very worth a post, but sometimes it takes me a while to get around to posting. This is my second attempt to catch up on these mailbag emails. Remember, feel free to email me questions or comments whether you want.
- Reader Aldo Piombino sent me an email last month after my post on potential Antarctic volcanism asking about some more unknown volcanoes. He brings up Mt. Marsili in the Tyrrhenian Sea (including a post of his own, in Italian), a volcano of which I was not aware. It is a submarine volcano (info on the volcano halfway down the page) off the coast of Italy that looks to be pretty big, but not much is known about it beyond that it is likely active but dormant. This volcano is related to fast seafloor spreading in the basin, at rates as high as 19 cm/yr! The other volcano Aldo mentions is Vavilov, another submarine volcano off Italy.
- Brian Owens sent me a link with a video from a CCTV camera in Pasto, Colombia that captured a Strombolian eruption of Galeras. Nice stuff.
Thanks for the emails!

Rob R. asks:
I've been following along with the recent happenings at Yellowstone (that is, as best as I can as a layman) but haven't seen that site [data from the Yellowstone GPS network] before. Could you explain (or link to) what I'm seeing there and what a "change in surface topography" might…
Monckton responding to an email about how volcanoes cause ozone depletion:
I'm not familiar enough with the inner workings of the
general-circulation models, so I'm not sure how it is that the ozone
hole appears only over the Antarctic. One possibility is that the
circumpolar circulation (which…
When I was designing my summer session class, I ran into a problem. If I really wanted my students to achieve the course goals, they would need to spend a lot of time on a computer. In a 3-times-a-week lecture course, I might expect them to do that work outside of class, but we were going to be…
