Gaussian volcanoes

It is not only in finance many people are relying on Gaussian models. Also in volcano modeling there exist Gaussian models. The picture is a hypothetical Gaussian volcano with sigma 5 kilometers. Add some stochastic volatility (sigma) and the model get slightly more realistic, then add some jumps and it is even more realistic.

Or even better listening to the music of the volcanos, if smooth and Gaussian stay calm

"Giant smoking volcanoes stand in a row like the pipes of a cosmic organ through which the mighty breath of the earth blows its roaring music." by Robert Scholten

By the way the picture is from a book "Earthquake and Volcano Deformation" (2010) By Paul Segall, an interesting book that contains many other quantitative models outside the Gaussian volcano.
