Strombolian eruption

Strombolian eruptions are relatively mildly explosive, with a volcanic explosivity index of about 2 to 3. They are named for the Italian volcano Stromboli, which is the eponym for the type. Strombolian eruptions consist of ejection of incandescent cinder, lapilli, and lava bombs, to altitudes of tens to a few hundreds of metres. The eruptions are small to medium in volume, with sporadic violence.
