This creates a caldera into which the surface collapses ( Figure below ). The composition of the eruption is felsic or highly felsic. Answer: supervolcano eruption
Output:
What kind of eruption do scientists think is caused by a very large magma chamber erupting entirely in one catastrophic explosion?
