Westdahl 1796
Start: 1796 [1]
Event Type: Other
- Lava flow [1]
- Lahar, debris-flow, or mudflow [2]
- Lava dome [1]
Description: From Miller and others (1998): "Coats (1950) attributed four eruptions in the late eighteenth century and early nineteenth century to Pogromni volcano. Based on recent observations from aircraft, however, Pogromni does not appear to have been active in historical time. The eruptions should probably be assigned to Westdahl."
Sapper (1917) reports that in 1796 ice and water came pouring down to a town called Nosowskoi. Coats (1950) reports a lava flow or plug dome and some explosive activity.
Simkin and Siebert (1994) assign the eruption a VEI of 0, indicating a non-explosive eruption.
