Tectonic (faulting), caldera and sector collapse, and erosional events are also simulated. In addition to a greater variety of eruption types, virtual 3-D with topographic and geological maps, and a greatly enhanced user interface, Erupt offers the user a built-in updater with web-access and features that make it a much more robust teaching and research tool.";
