Westdahl 1827/3
Start: March 1827 [1]
Stop: 1829 [1]
Event Type: Explosive
Max VEI: 2 [2]
- Lava flow [1]
- Tephra plume [3]
- Minor explosive eruption [4]
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."
Grewingk (1850, translated 2003 by Fritz Jaensch) reports that Isenbeck said that Pogromnaia was belching fire in 1827, and "Lastly, on the southern side of Unimak, on the west side of Tugamak Gulf [Unimak Bight], the location of which is not accurately fixed, but probably not far from Pogromnoi Volcano, there, in September of 1827, according to the log of the corvette Moller, a 'lava brulante' was observed, meaning most likely a not-yet-cooled lava stream. Dr. Isenbeck reports (oral report) that during the passage through the Strait of Unimak, a fiery column constantly ascended from the volcano closest to the coast. This was probably Pogromnoi Volcano, although Veniaminov's indications, according to which the Shishaldin erupted at the same time, speak against it."
Powers (1958) reports an ash eruption.
