Description: Grewingk (1850, translated 2003 by Fritz Jaensch) writes that Litke reported "renewed eruption," an "enormous eruption after long dormancy." in 1824. The English translation of Litke "A voyage around the world, 1826-1829) does not contain reference to this event. However, the English translation does not cover all of Litke's publications for this voyage, which he published in both Russian and French.(Dall (1870) writes that a "major eruption took place on Yunaska." Petroff (1884) writes that "[Y]unaska in violent eruption after a long repose." Becker (1898) reports this eruption as a "great eruption." Powers (1958) reports this eruption as an ash eruption.)

Veniaminov (as translated by Black and Geoghegan, 1984) writes that in 1825 "The peak on Iunaska Island, which burned in antiquity but then went out, also in time immemorial, exploded at the beginning of 1825 with a thunderous roar heard on Umnak. Its summit collapsed with an accompanying expulsion of burned rocks (gorely kamen'ia - pumice) which floated on the sea even until June. Since then it has smoked incessantly."

Sapper (1917) reports that Perrey said the eruption continued "until the end of June, with stones thrown out" leaving which year or years the eruption occurred in still uncertain.

Perhaps this description refers to this eruption from Yunaska; perhaps the eruption occurred around the end of 1824 and beginning of 1825, explaining the discrepancy in years. Khlebnikov (translated in 1994) seems to support this theory, as he relays what Davydov reported: "In the winter of 1824-1825 a mountain erupted on Iunaska Island. It was not very high and did not have a sharp peak. Toion Ivan Pan'kov, who was sent to this island with a party of Aleuts to hunt sea otters in the spring of 1825, found the appearance of the island completely altered. All the shores were covered with igneous rock, while thick smoke streamed from the mountain, which, when the nights were dark, glowed like fires. In June 1827, passing within sight of this island, we noticed smoke coming out of a mountain on the island."
