Fast-forward your volcano
Remember a couple of months ago when Google Earth Timelapse got updated? I didn’t spend a lot of time looking at it back then, but I’ve taken it for a spin since then and – being a volcanologist – decided to look at volcanoes. And it turned out to be a lot of fun.

This interests me at the moment for a number of reasons, besides the fact that finding out anything new about Mars is just cool. First reason: I’m taking a remote sensing class right now, and we’re getting ready to do projects that involve tasks …
