| 1852-00-00 | | Chiginagak: 1852 | Coats (1950) reports that Chiginagak was smoking in 1852. Powers (1958) writes that Chiginagak was steaming, with intermittent smoke in 1852. Perhaps the original source for this event is Doroshin, who viewed Chiginagak in 1852 and described it as follows (J.B. Kisslinger translation, 1983): "This volcano, which I also saw rising from behind some mountains, has a broad crater, the southern side of which has been destroyed. Snow shows white within the crater. Smoke rises from the western slope ...

| 1929-03-00 | | Chiginagak: 1929 | Jaggar (1932): "A mountain to the west of Kanatak was reported fuming in March 1929, and this description might apply to Chiginagak."
However, Miller and others (1998) report that the 1929 eruption of Chiginagak was "based on a brief newspaper account of "unusual activity" at Chiginagak and 6 other volcanoes observed by the crew of a ship which probably passed no closer than 25 km." The December 14, 1929 Associated Press article does not provide further information on Chiginagak, except to ...

| 1971-07-00 | 1971-7-00 | Chiginagak: 1971 | From Miller and others (1998): "Mr. Odon Soeth reported observing an ash eruption in July, 1971 from Port Heiden, 100 km southwest of Chiginagak; according to Mr. Soeth, the eruption lasted only one evening." | asterisk_yellow.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Chiginagak&eruptionid=181&page=basic | |
| 1997-10-22 | 1998-8-21 | Chiginagak: 1997 - 1998 | From McGimsey and Wallace (1999): "On October 22, 1997, AVO began receiving pilot reports of increased steaming, snowmelt, and sulfur smell at Chiginagak. Residents of Pilot Point and surrounding areas also reported that they began noticing an increase in steam emissions possibly as early as mid-summer 1997. A thermal anomaly was detected on Advanced Very High Resolution Radiometer (AVHRR) imagery analyzed on October 23, 1997 [see fig. 10 in original text]. During a flight around the volcano ...

| 2000-12-00 | | Chiginagak: 2000 | From Neal and others (2004): "In late December 2000, Navigation Officer Daniel Karlson contacted AVO to report observations of steaming from Chiginagak Volcano in late July and early August during NOAA operations off the Pacific coastline of the Alaska Peninsula. By their estimate, the steaming emanated from a source at approximately 5,200 ft (1,580 m) on the north flank of the volcano, approximately the position of the well-known fumarole long described for Chiginagak. Karlson noted that the ... More information | information.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Chiginagak&eruptionid=511&page=basic | |
| 2005-05-00 | | Chiginagak: 2005 | From McGimsey and others (2007): "Between November 2004 and early May 2005, a flux of heat to the summit area caused melting of more than 1.3x10^7 cubic m (4.6x10^8 cubic ft) of ice and snow filling the summit crater of Chiginagak, resulting in a 400-m wide (~1,300 ft) and 105-m deep (~350 ft) cauldron containing an acidified lake (Schaefer and others, 2005; J.R. Schaefer and others, AVO/ADGGS, written commun., 2007) (see figs. 25 and 26 in original text). In early May 2005, a catastrophic release ...
