Sunset Crater factsThe eruptions that produced Sunset Crater and several nearby flows and smaller cones began sometime between the 1040 and 1100 AD. Eruptions may have continued on and off for several months or years. 0.07 mi3 (0.3 km3) of magma erupted from the Sunset Crater vent system. About 75% of the magma erupted at Sunset Crater erupted explosively as scoria. About half of the scoria fell very near its source and built Sunset Crater cinder cone, about half blanketed the region with ash and other small volcanic particles.About 25% of the magma was erupted as lava flows. 75% of the lava now forms the Bonito Lava Flow. All of the vents in the Monument produced similar magma compositions. |
