The type of eruption that is characterized by an abundant pyroclasts is Strombolian eruption. Large blobs of lava and hot rock, called pyroclasts, are tossed from its central vent during this eruption.

Vulcano's highest VEI (volcanic explosivity index) occurred in 183 BC, and was recorded by human observation. The most recent destructive eruption occurred in 1888, and involved a central vent eruption, lahars, and pyroclastic flows.

it is a vent that is in the center obviously

Vent

When a secondary vent opens on a volcano the name can depend based on the type of eruption as well as the type of volcano. If a Shield Volcano has a secondary vent eruption it is called a rift eruption. This is demonstrated in the current eruption on Kileaua volcano in Hawaii. In a stratovolcano a secondary vent can either be a rift vent, or a cinder cone. This depends on the nature of the eruption. If it is a moderate explosive eruption with minor lava effusion than it would develope into a cinder cone, while if it is a constant lava spatter it would be deemed a rift zone eruption. There are several other minor terms of events, however they are extremely rare and are associated with both of these types of eruptions.
