Volcano quadcopters in xkcd 1608

I got a tweet from @JulianHzg today alerting me to the latest brilliant xkcd, which features an interactive "hoverboard" game.

The world in hoverboard is giant and brilliant, and there are so many easter eggs in there, it's ridiculous! It was fun to find volcano quadcopters in there, except that I maintain that it is possible to capture good volcano footage and have a quadcopter survive. ;)

If you want to go find the volcano and the quadcopters yourself, here's a map:
