Description: From Miller and others (1998): "Recorded activity in 1878 may have been form a radial fissure eruption on the west flank; this event may have produced the youngest dacite flow, which extends west-southwest to Cape Kigushimkada (Byers, 1959)." Sapper (1917) wrote that Vsevidof had a brief flame and ash eruption and a new crater developed from which came steam and hot cooking mud. This new crater appeared between Vsevidof and the settlement. Sapper also notes that there were many hot springs. Hantke (1962) notes that about 1878 large lava streamed out of ruptures in the west flank. The eruption lasted less than two years: Dall (1918) writes that he saw Vsevidof in 1880, the "image of perfect peace", and does not mention the 1878 event.
