Mageik 1923
Start: 1923 [1]
Event Type: Not an eruption
- Fumarolic or hydrothermal activity [1]
- Steam [1]
Description: Fenner (1930) reported a constant heavy roar and steam at Mount Mageik in 1923, stating that "rocks and ash on rim of crater suggest recent eruption."
Fierstein and Hildreth (2001) discount this account as an eruption: "Not a single one of the 20th century tephra eruptions of Mageik listed in Simkin and Siebert's (1994) "Volcanoes of the World" seems plausible. Configuration of the crater has not changed since it was first photographed in 1923; there are no juvenile ejecta in the crater or around its rim (except a scattering of 1912 pumice clasts from Novarupta); and the only late Holocene fall deposits on the or near the lower flanks of Mageik are the Novarupta pumice falls of 1912 and the black Trident ash of 1953."
