Lava-flow morphology is determined by cooling rate, viscosity, yield strength, eruption rate, topography, total mass, and other various factors. We have made a numerical flow model, assuming nonisothermal laminar Bingham flow, in which we take the self-gravity and cooling mechanisms into account. Because the calculation method is a type of cellular automata on square meshes, we can apply our numerical...
VAST is a program written in C to calibrate thermal data for active volcanoes from the satellite-borne Advanced Very High Resolution Radiometer (AVHRR), locate thermally anomalous pixels containing active volcanic features, and produce output useful for monitoring activity at the target volcano. Testing the software on sub-images of active volcanic features at Mount Etna, Vulcano and Stromboli volcanoes,...
