Question

_________ eruptions are common first phases in the eruptions of volcanoes as they "clear their throats" before emitting larger eruptions.

Answer 1

Vulcanian-type eruptions are common first phases in the eruptions of volcanoes as they "clear their throats" before emitting larger eruptions. They are small and short eruptions but they tend to be violent explosions of viscous magma. They can be repetitive and go on for days to years long.
