Strombolian eruption

[1] Strombolian eruptions consist of ejection of incandescent cinders, lapilli, and volcanic bombs, to altitudes of tens to a few hundreds of metres.

The tephra typically glows red when leaving the vent, but its surface cools and assumes a dark to black colour and may significantly solidify before impact.

The lava flows are more viscous, and therefore shorter and thicker, than the corresponding Hawaiian eruptions; it may or may not be accompanied by production of pyroclastic rock.

[2] Such eruptions are associated with higher magma gas content, leading to a turbulent churn flow regime in the conduit, producing stronger and much more frequent explosions.

[4] Violent Strombolian eruptions are more explosive in nature than their regular counterparts (up to VEI 3),[5] and may produce sustained lava fountains,[4] long distance lava flows,[6] eruption columns several kilometres in height,[2] and heavy ash fallout.
