This is a questionable event. Description:
|Start:||December 1829 ||Observed|
|Stop:||December 1830 ||Observed|
Grewingk (1850, translated 2003 by Fritz Jaensch) writes that Ingenstrom reported Korovin smoking in 1829 and 1830. Petroff (1884) reports Korovin as "in eruption and smoking" during 1829 and 1830. However, because Petroff (1884) is an incomplete translation of Grewingk (1850) the smoke-only reports are probably more accurate.
Additionally, the following account written by Bank and others (1950) may pertain to this eruption: "During the early eighteen hundreds Sarychef and Korovin volcanos [sic] on Atka commenced throwing off increasing amounts of ash, so that the priest decided that Korovinsky must be abandoned. The seat of the Russian Church was transferred to Unalaska as was the trading center, and the villagers were moved to the site of the present village on Nazan Bay. An interesting story concerning this forced move was told to me by a young Aleut hunchback, Johnny Prokopeuff, whose father had related it to him before he died. I quote the story as we recorded it: 'Long time ago before peoples lived in this village Akta peoples live over at Old Harbor. Was a big village with lots of barabaras and big Russian buildings. There was man, Russian priest, name of Father Salamatoff who was kind to people. He brought peoples from all around, Chugul, Kagalaska villages, Adak, to live at Old Harbor. Another priest after Father Salamatoff died, I don't remember his name, told peoples they had to move village, said that mountain was going to come down and cover Old Harbor. All the time at night the sky was red, and lost of little rocks (ash) in the air so that peoples sick. Everyone moved over to this place and build village on Nazan Bay side. Priest, he say that peoples safe here. Mountain not come down on Old Harbor, but all the time at night lots of noise and red fire in the sky. Big rocks roll down mountain. Lots better on Nazan Bay, more fish.'" It is difficult to know which eruption this account is describing - Father Salamatoff died in 1864, and this account may somehow refer to the 1812 eruption of Kliuchef, the 1829-1830 eruption of Korovin, or another eruption entirely.
