Isla Asunción

Asuncion

Estratovolcán · United States · 857 m

An aerial view from the SW shows the upper slopes of Asuncion in the northern Mariana Islands. It forms a circular 3-km-wide island that has had no permanent residents since the late 17th century. An explosive eruption in 1906 produced lava flows that descended about halfway down the W and S flanks.

Resumen geológico

A single large asymmetrical stratovolcano forms 3-km-wide Asuncion Island. The steeper NE flank terminates in high sea cliffs, while the gentler SW flanks have low-angle slopes bounded by sea cliffs only a few meters high. The southern flank is cut by a large landslide scar. The S and W flanks are covered by ash deposits. An explosive eruption in 1906 produced lava flows that descended about halfway down the W and SE flanks, but several other eruption reports are of uncertain validity.
