Grewingk (1850, translated 2003 by Fritz Jaensch): writes that there was an expulsion of ashes from Yunaska in 1830.
Mushketov and Orlov (1893, translated in 1994 by Katharine Arndt) wrote: "In the same year  an earthquake at the volcano Yunaka [sic; Yunaska?] and an eruption of flame and ash, in which there appeared a torrent which formed from melted snow or from rain and, like the sea water, was colored black." Mushketov and Orlov cite Grewingk (1850) and Perrey (1866).
