Start: May 19, 1949 [1]

Stop: May 19, 1949 [1]

Event Type: Not an eruption

Event Characteristics:
  • Remobilized tephra - no eruption [1] [2]

Description: 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 1953 - 1968." The ash seen by Eicher was probably remobilized from the 1912 eruption.
