Westdahl 1830

Start: 1830 ^[1]

Event Type: Other

Event Characteristics:

Tephra plume ^[2]

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."
Petroff (1884) reports an eruption in autumn of 1830, but Grewingk (1850, translated 2003 by Fritz Jaensch) suggests the eruption is from Shishaldin. Becker (1898) lists an 1830 eruption with ashes.
