|1778-00-00||Redoubt: 1778|| Captain James Cook saw Redoubt during the summer of 1778, "emitting a white smoke but no fire which made some think it was no more than a white thick cloud such as we have frequently seen on the Coast, for the most part appearing on the sides of hills and often extends along a whole range and at different times falls or rises, expands or contracts itself and has a resemblance to Clouds of white smoke. But this besides being too small for one of those clouds, remained as it were fixed in the same ...

|1819-00-00||Redoubt: 1819|| Grewingk (1850, translated 2003 by Fritz Jaensch): "Since [Redoubt] became known in 1819, it has been smoking (Wrangell)." Most subsequent compilers do not consider this event to be a volcanic eruption.||information.png||ye||50||http://www.avo.alaska.edu/volcanoes/activity.php?volcname=redoubt&eruptionid=435&page=basic|
|1881-00-00||Redoubt: 1881|| From Cordeiro (1910): "To the eastward, Redoubt Volcano, 11,060 feet high, is constantly smoking, with periods of exaggerated activity. Fire has been seen issuing from its summit far out at sea. A great eruption took place in 1881, when a party of native hunters half-way up its slopes were overwhelmed by a lava-flow and only two escaped." This account is not mentioned in other eruption compilations.||asterisk_yellow.png||ye||50||http://www.avo.alaska.edu/volcanoes/activity.php?volcname=redoubt&eruptionid=436&page=basic|
|1902-01-18||1902-6-21||Redoubt: 1902|| From the Daily Alaska Dispatch (1902): "Word has just been received that Redoubt, one of the volcanoes at Cook's Inlet had an eruption on January 18, and the country for 150 miles around was covered with ashes and lava. The news comes from Sunrise, but nothing definite has been ascertained as to whether any damage was done, for no boats have as yet been in the neighborhood of the volcano.
"On the date of the eruption the sky was darkened and at Sunrise, the snow was covered so thick with ... More information||exclamation.png||ye||50||http://www.avo.alaska.edu/volcanoes/activity.php?volcname=redoubt&eruptionid=437&page=basic|
|1933-05-05||Redoubt: 1933|| Till and others (1993) summarize this event as follows: "Following an earthquake in May 1933, Redoubt was observed 'belching smoke,' which was unusual since it 'had never been known to emit anything more than a slight wisp of smoke' (Fairbanks Daily News-Miner, May 25, 1933). The report does not mention tephra or that the smoke was dark in color. Hence, it seems likely that the activity was water-vapor emissions rather than an eruption."
Newspaper accounts of this event state that Captain ... More information||asterisk_yellow.png||ye||50||http://www.avo.alaska.edu/volcanoes/activity.php?volcname=redoubt&eruptionid=438&page=basic|
|1965-01-28||Redoubt: 1965|| From Till and others (1993): "In January and February of 1965, pilots reported that five fissures had opened on the southeast wall of Redoubt and were emitting water vapor and hot gases (Anchorage Daily News, January 29 and 30, 1965; Fairbanks Daily News-Miner, February 4, 1965)." This activity does not constitute a volcanic eruption.
From the Associated Press (1965): "A fifth fissure has opened high on the southeast wall of troubled Mt. Redoubt, 125 miles southwest of here.

|1966-01-24||1968-4-28||Redoubt: 1966 - 1968 || From Till and others (1993): "[O]n January 24, 1966, Redoubt erupted. 'Giant black puffs' of tephra rising 6,000 m above the summit were reported (Anchorage Daily News, January 25, 1966). A 22-man seismic crew camping and working along the lower Drift River was evacuated following flooding of the river as a result of the eruption. According to their account (Anchorage Daily News, January 26, 1966), the ice-bound river broke up suddenly and water rose 1 to 1.2 m in 15 minutes, carrying chunks ...

|1989-12-14||1990-6-00||Redoubt: 1989 - 1990 || From Miller and others (1998): "The most recent eruption at Redoubt began with a major phreatomagmatic, vent-clearing explosion at 9:47 am on December 14, 1989 (Brantley, 1990; EOS, 1990; Miller and Chouet, 1994) after less than 24 hours of intense precursory seismicity. Three more ash-rich explosions occurred the following day, December 15, with the last blast generating a pyroclastic flow down the Drift Glacier. The resulting debris flow contained entrained ice blocks as large as 10 m across ...

|1992-04-30||Redoubt: 1992|| From McGimsey and others (1995): "On April 30, pilot reports of 'a plume to 20,000 ft over Iliamna volcano' set off a chain reaction that culminated in a widespread rumor that an eruption had occurred or was in progess at Iliamna volcano. Subsequent reports also indicated Redoubt volcano was erupting. AVO promptly issued a widely distributed information release stating that no eruptive activity had occurred at any Cook Inlet volcano. Staff spent the afternoon answering dozens of calls and initiating ...

|2003-11-25||Redoubt: 2003|| From McGimsey and others (2005): "On November 25, 2003, an employee on the 18th floor of the Conoco Phillips Building in downtown Anchorage reported a 'white plume' over the general vicinity of Redoubt. Seismograms and spectrograms revealed nothing unusual other than typical wind noise. AVO staff called the CWSU of the FAA to request a PIREP from any planes flying over Redoubt and a short while later learned that there was 'no steam but plenty of blowing snow'.

|2009-3-15||2009-7-00||Redoubt: 2009||From Schaefer (ed), 2012: "Redoubt Volcano, an ice-covered stratovolcano on the west side of Cook Inlet, erupted in March 2009 after several months of escalating unrest. The 2009 eruption of Redoubt Volcano shares many similarities with eruptions documented most recently at Redoubt in 1966-68 and 1989-90. In each case, the eruptive phase lasted several months, consisted of multiple ash-producing explosions, produced andesitic lava and tephra, removed significant amounts of ice from the summit crater ...
