Large volcanic calderas, aka super volcanoes, are enormous craters tens of kilometres in diameter produced by giant, explosive eruptions that rank among the most violent geologic events. Geophysical studies of recently active calderas and investigations of their eruption products suggest that their magmatic systems are driven by intrusion of mantle-derived basalt in the deep crust, a process commonly referred to as magmatic underplating.

Survival of U.S. state geological surveys
The annual meeting of the state geologists wrapped up Wednesday night and it’s clear that state geological surveys across the nation are generally hurting from the economic mess.
