Geologic Background:
A single large asymetrical volcano,
steeper on the NE, forms 2.6 x 3.4 km wide Asuncion
Island. The steep NE flank terminates in high sea cliffs.
The southern and western flanks are mantled by ash
deposits that may have originated in historical time.
Historic Activity:
- An explosive eruption in 1906 also produced lava
flows, but other historical eruption reports are of
uncertain validity.
Recent Activity:
- Vigorous steaming was occuring from several locations
in the summit crater during observations on May
18,1992.
Data Sources:
- Information from Global Volcanism Network (V. 17, No.
6)
