Mageik 1946
Start: 1946 [1]
Event Type: Not an eruption
Max VEI: 2 [2]
- Active; type of activity not specified [1]
Description: Coats (1950) lists a questionable explosive eruption at Mount Mageik in 1946. Fierstein and Hildreth (2001) doubt the validity of this report, stating: "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."
