In my mind, I see Pompeii, if that explains things a bit.
Yeah - I’m more of a Mount Saint Helens guy with 1/4 of the mountain blown off. (I live near Seattle, waiting for Mount Rainer. It won’t blow like Mt. Saint Helens, but could send a debris flow 30 feet thick and miles wide and miles long that will cover the suburbs built in their path.) Some of those suburbs are built on the old debris flows. It spooks me just driving through some of those valleys. Although in the past 10 years they have made lots of improvements to monitoring the mountain and setting up warning signals. But the nearest town only has something like 7 minutes to head to high ground. At least the schools are near hills and the kids will have enough time to walk up the hill a bit. I just did a job where they were building a new fire station up on the hill to replace the one built in the valley.
Pretty interesting all the different forms of volcanoes. As long as your friend isn’t an idiot posting the videos from 5 feet away of the flowing lava (and perhaps within range of a spluttering blob of lava) - he’ll be okay! And perhaps if he has an extra room he could even make some money renting out the space to reporters, scientists and tourists!
