The name is derived from the volcano, of course, and it is characterized by mild eruptions, with more violent eruptions occurring very rarely. Strombolian eruptions are capable of ejecting cinders, lava bombs, and lapilli to heights of several dozen to several hundred meters. In the Volcanic Explosivity Index, which has an open-ended scale (with magnitude 8 recorded on Earth to date), strombolian eruptions are classified as having a magnitude of 1 to 2. Another characteristic of strombolian eruptions is regular explosion intervals that vary from seconds to minutes. Lava flows in strombolian eruptions are more viscous but short-lasting.
