| 1912-06-06 | 1912-6-9 | Novarupta: 1912 | Fierstein and Hildreth (2001) provide information about the magitude of the 1912 eruption at Novarupta and Katmai: "The world's largest volcanic eruption of the 20th century broke out at Novarupta [see fig. 1 in original text] in June 1912, filling with hot ash what came to be called the Valley of Ten Thousand Smokes and spreading downwind more fallout than all other historical Alaskan eruptions combined.

| 1949-05-19 | 1949-5-19 | Novarupta: 1949 | Eicher and Rousefell (1957) give the following account of a 1949 eruption at Novarupta: "Following a long period of dormancy Novarupta erupted violently for approximately two hours on May 19, 1949, a heavy outfall of ash being carried down Shelikof Strait by a westerly wind (observed by senior author)." However, Hildreth (1983) states: "Published compilations notwithstanding, there are no credible reports of historic eruptions in the Katmai group except at Novarupta in 1912 and at Trident in ...

| 1950-07-00 | | Novarupta: 1950 | From Sumner (1952): "In 1950 National Park Service observers discovered at its base [Novarupta's] a small new cone, perhaps fifty feet high, which apparently had been pushed up during a minor outburst of activity observed abut the first of July that year." However, Hildreth (1983) states: "Published compilations notwithstanding, there are no credible reports of historic eruptions in the Katmai group except at Novarupta in 1912 and at Trident in 1953 - 1968." | information.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Novarupta&eruptionid=504&page=basic | |
