1763-00-00		Kanaga: 1763	From Grewingk (1850, translated 2003 by Fritz Jaensch): 1763, pg. 121: "volcano with crater where sulfur was collected (solfatara), and hot springs (Tolstykh). Page 122: "Kanaga solfatara." Coats (1950): 1763, Kanaga active; type of activity unspecified.	asterisk_yellow.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=34&page=basic
1786-00-00		Kanaga: 1786	Grewingk (1850, translated 2003 by Fritz Jaensch) reports that Shelikhov said Kanaga was erupting with fire in 1786.	exclamation.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=157&page=basic
1790-00-00		Kanaga: 1790	From Grewingk (1850, translated 2003 by Fritz Jaensch): "1790 and 1791, smoke rising from the hot springs at the base of a once-active volcano (Sauer, Sarychev)." Coats (1950): 1790, Kanaga was "active; type of activity unspecified." Sauer, June 17, 1791: "We made the island of Kanaga seven miles distant from that of Tanaga, and saw the smoke ascending from the hot spring at the base of an extinguished volcano on the island of Kanaga, off which at 12 miles we also observed the small island called ...

1791-06-17		Kanaga: 1791	From Grewingk (1850, translated 2003 by Fritz Jaensch): "According to Sauer (Engl., p. 226, German, p. 259) and Sarychev (II, p. 76) smoke was seen on the seventeenth of June 1791. It came from the hot springs of the formerly active volcano." Coats (1950) reports smoke at Kanaga in 1791.	information.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=36&page=basic
1827-00-00		Kanaga: 1827	Grewingk (1850, translated 2003 by Fritz Jaensch) writes that Lutke reported Kanaga smoking in 1827. It is uncertain if this "smoke" was simply fumarolic activity from Kanaga's active fumaroles or if it was from an actual eruption.	asterisk_yellow.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=37&page=basic
1829-00-00		Kanaga: 1829	Grewingk (1850, translated 2003 by Fritz Jaensch) writes that Kanaga was smoking in 1829.	asterisk_yellow.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=38&page=basic
1904-00-00		Kanaga: 1904	Jaggar (1927) writes that Kanaga was "very active" in 1904. Coats (1950) speculates that the southern flow on Kanaga was perhaps emitted in 1904 from the upper south flank. Miller and others (1998) combine this 1904 eruption with the 1906 eruption as one event.	exclamation.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=39&page=basic
1906-05-00		Kanaga: 1906	From Miller and others (1998): "A trapper living on the island in 1906 experienced several earthquakes and witnessed lava pouring down both east and west sides of the cone. Coats (1956) interpreted these flows to be the ones now present on the northeast and southwest slopes of Kanaga Volcano." Coats (1956): "An eruption in May 1906 was reported in a letter to the writer from Simeon Oliver, teacher at Atka, who obtained his information from William Dirks of Atka. According to Dirks, who was ... More information	exclamation.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=40&page=basic
1933-00-00		Kanaga: 1933	Coats (1950) specified that Kanaga was "active; type of activity unspecified" in 1933. However, newspaper articles from that time period specify that "Great Sitkin volcano" on "Kanaga Island" was in eruption at this time. A few articles are more clear, stating that "reports from Kanaga Island" state that Great Sitkin was in eruption. It seems likely that reports of Kanaga erupting in 1933 are erroneous.	information.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=43&page=basic
1942-00-00		Kanaga: 1942	Hantke (1951) lists an eruption at Kanaga in 1942.	exclamation.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=44&page=basic
1951-00-00		Kanaga: 1951	Jones (1951) reported "Minor ash showers and fume emission are known to have occurred during 1951 from Gareloi, Kanaga, Great Sitkin, Akutan, and Shishaldin."	asterisk_yellow.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=47&page=basic
1994-01-00	1995-00-00	Kanaga: 1994 - 1995	From Miller and others (1998): "The eruption was characterized by steam and ash plumes rising to as high as 7.5 km and drifting a few tens of kilometers downwind, lava extrusion within the summit crater, and minor avalanching of incandescent debris down the north flank reaching the sea in some cases (Neal and others, 1995). Strong sulfur odors were detected on occasion by ground observers in Adak, 33 km to the east." From Neal and others (1996): "Report of increased steaming by U.S. Navy ...

1996-06-11		Kanaga: 1996	From Neal and McGimsey (1997): "Possible small (phreatic?) ash eruption, continued avalanching of debris from cooling lava flows. "On June 11, [1996] a commerical airline crew noted a small, bluish-brown cloud possibly containing some ash, rising a few hundred feet above the summit of the volcano, discoloring the snow. The flight crew noted a sulfur smell upon descent into Adak. A ground observer from Adak Island noted dark 'splotches' on the east flank of Kanaga, but a ballistic origin ...

2012-2-18	2012-2-18	Kanaga: 2012	On February 18, 2012, AVO detected volcanic tremor from 15:23-15:27 UTC, followed by numerous small events for about an hour at Kanaga Volcano. A possible weak ash cloud about 8 km in length was detected in AVHRR satellite data from 15:35 UTC, about 39 km (24 mi) NE of the volcano. Because of the new unrest and possible explosive activity with likely ash cloud, AVO raised the alert level to ADVISORY and the aviation color code to YELLOW. Somewhat elevated seismicity continued at Kanaga on the 19th, ... More information	exclamation.png	ye	50	http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Kanaga&eruptionid=693&page=basic
