Bogoslof 1913/7
Start: July 1913 [1]
Event Type: Other
Description: Powers (1916) gives the following information on this eruption: "[I]n July, 1913, a brief statement refers to the crater [of Tahoma Peak] as being plainly visible with steam and smoke slowly issuing from it. Activity apparently ceased during this year, for the commanding officer of the steamer Patterson, which passed Bogoslof on its way to pick up survivors of the Tahoma [The Tahoma struck a reef on the 20th of September, 1914], reports that 'the Bogoslof Islands showed three peaks in 1914, none of which was smoking.'"
Jaggar (1930) relates similar information: "In July, 1913, this crater had steam and smoke slowly issuing from it, but the following year all smoking had ceased. During the next eight years Tahoma Peak, as the new hill of 1910 was called, was eroded away, and a channel was again opened between Castle Rock and Grewingk so that a boat could sail between the two older islands. Grewingk had greatly diminished in size, and Castle Rock was now two rocky horns with a big accumulation of sand and gravel heaps piled against them, especially on the northern and eastern sides, these trailing off into a long sand spit at the north, and the whole of this larger island was surrounded by sand beaches."
