What kind of eruption do scientists think is caused by a very large magma chamber erupting entirely in one catastrophic explosion?
supermagma eruption
brucei eruption
mangxamba eruption
supervolcano eruption
The exact cause of supervolcano eruptions is still debated. However, scientists think that a very large magma chamber erupts entirely in one catastrophic explosion. This creates a caldera into which the surface collapses ( Figure below ). The composition of the eruption is felsic or highly felsic.
