Details for: Asuncion
An aerial view from the SW shows the unvegetated upper slopes of 857-m-high Asuncion volcano in the northern Mariana Islands. The large asymmetrical stratovolcano 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 half way down the western and SE flanks, but several other historical eruption reports are of uncertain validity.
