Description: Grewingk (1850, translated 2003 by Fritz Jaensch) writes that Shelikov reported Amukta "all in flames" in June of 1786, and Sarychev reported it active in 1790. In Grewingk's chronological table of eruptions, he writes that Amukta was active from 1786 through 1791. The English translation of Sarychev is less clear: "On the morning of the 29th we passed the island Amuchta at a distance of 6 miles. It is about 27 miles in extent, and is said to have a volcano."

Shelikhov (translated in 1981 by Marina Ramsay) writes: "During this voyage [the return] we saw the Islands of the Four Mountains and Amukhta. Because of active volcanoes the latter seemed to be enveloped in flame."

Sapper (1927) estimates a tephra volume of 10^7 to 10^9 for this eruption; the Smithsonian Global Volcanism Database uses this estimate and, in turn, estimates a tephra volume of 5.1 +/- 5.0 x 10^8 cubic meters.
