Classification of Volcanic Eruptions » Strombolian Eruptions

In a Strombolian-type eruption, huge clots of molten lava burst from the summit crater to form luminous arcs through the sky. The lava fragments consist of partially molten volcanic bombs (see for more information) that fly through the air. Lava clots collect on the flanks of the cone, and combine to stream down the slopes in fiery rivulets. Particularly violent Strombolian explosions can produce ash clouds but they are normally short-lived and do not rise high into the atmosphere.
