We used the UC Davis augmented reality sandbox design to make a deforming volcano with a simple hand pump, tube, and balloon. The result? An inflating and deflating volcano and the formation of a crater lake. Add a few GPS/GNSS instruments made from toothpicks and gumdrops and some bullet-level tiltmeters, and your volcano is instrumented. (The fish is optional.) Deformation is one of the key techniques in volcano monitoring. It can tell us about where magma is located beneath the volcano, whether a volcanic system is recharging or relaxing, and, along with other signs like seismicity and gas emissions, when a volcano is likely to erupt.
