“I don’t know that!” – Accretionary Wedge #31

Jim Lehane at The Geology P.A.G.E. is hosting this month’s Accretionary Wedge, and asks:

What geological concept or idea did you hear about that you had no notion of before (and likely surprised you in some way)?

I can’t think of any particular moments where something like this hit me all at once, but one concept that I’ve encountered as a grad student strikes me as something that I never really thought about much as an undergrad (or as a kid who liked volcanoes, for that matter). It’s the idea that an eruption style at a single volcano – not just in a region – can change dramatically in a relatively short period of time.
