| 1931-05-01 | 1931-6-13 | Aniakchak: 1931 | From Neal and others (2001): "In the last 200 years, Aniakchak volcano is known to have erupted once - during about six weeks in May - June 1931. Documentation of the event is limited; the following summary is derived principally from the writings of University of Santa Clara missionary and explorer Hubbard (1931; Jan 2 and 16, 1932), who visited Aniakchak in 1930 and 1931.
The 1931 eruption was violent, included both explosive and effusive phases, and sent ash at least 600 km north of the ... More information | exclamation.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Aniakchak&eruptionid=293&page=basic | |

| 1951-06-25 | 1951-6-25 | Aniakchak: 1951 | Reeder (1987) reported that Pilot Everett Skinner observed "an extensive eruption cloud" from Aniakchak on June 25, 1951. This event is generally thought to be a resuspension of ash particles rather than a volcanic eruption. | information.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Aniakchak&eruptionid=316&page=basic | |
| 2004-12-15 | 2005-2-3 | Aniakchak: 2004 - 2005 | From McGimsey and others (2007): "Beginning in mid-December 2004 and continuing into January 2005, several series of 10-20 low-frequency seismic events showed up on the Aniakchak seismic network. On January 11, 2005, returning form an observation flight over nearby Veniaminof Volcano AVO staff photographed a partially ice-free Surprise Lake wihtin the Aniakchak caldera (see fig. 29 in original text). A thermal anomaly of unknown source was detected in satellite data on February 1-3, 2005. Subsequent ...

| 2008-3-8 | 2008-3-14 | Aniakchak: 2008 | Seismometers at Aniakchak Volcano appeared to record anomalous seismicty at Aniakchak during the spring of 2008. Further analysis revealed that the signals were a product of icing on the seismometers, and not of volcanic origin.
From Neal and others (2011): "AVO seismic analysts noted a swarm of seismic events at Aniakchak during routine seismic checks of Alaskan volcanoes on March 8. The activity continued intermittently over the next week with events occurring as frequently as 5-10 per hour. Interpreting ...
