| 1786-00-00 | 1790-00-00 | Seguam: 1786 - 1790 | Grewingk (1850, translated 2003 by Fritz Jaensch) states that from 1786 until 1790, Seguam was active. Sarychev (translated from Russian in 1806 and 1807, republished 1969) wrote that in 1790, Seguam was "formerly to have had a volcanic mountain." | exclamation.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Seguam&eruptionid=80&page=basic | |
| 1827-00-00 | | Seguam: 1827 | Grewingk (1850, translated 2003 by Fritz Jaensch) states that Seguam was reported smoking in 1827 by Lutke. | asterisk_yellow.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Seguam&eruptionid=81&page=basic | |
| 1891-12-00 | | Seguam: 1891 | Jaggar (1927) reports Seguam "broke into eruption for a week in December, 1891." Coats (1950) classifies the eruption as a minor explosive eruption. | exclamation.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Seguam&eruptionid=82&page=basic | |

| 1902-00-00 | | Seguam: 1902 | Coats (1950) and Dunn (1906) report a suspected major explosive eruption at Seguam in 1902. Miller and others (1998) and McGimsey and Miller (1995) report that this eruption occurred in 1901. | asterisk_yellow.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Seguam&eruptionid=84&page=basic | |
| 1927-00-00 | | Seguam: 1927 | Coats (1950) reported smoke from Seguam during 1927. | asterisk_yellow.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Seguam&eruptionid=85&page=basic | |
| 1977-03-06 | 1977-3-8 | Pyre Peak: 1977 | From Miller and others (1998): "In early March, 1977 the crew of the U.S. Coast Guard Cutter Mellon reported eruptive activity. Eight lava fountains, up to 90 m high were noted along a radial rift about 1 km long and about 2.5 km southwest of the summit. At least two tongues of lava were extruded. The larger flow, 1 km wide, extended 1 km south. Neither tongue entered the sea. Pyroclastic material was also produced during the event. Dense clouds containing black ash and incandescent fragments ...

| 1992-12-27 | 1992-12-30 | Pyre Peak: 1992 | From McGimsey and others (1995): "On December 27, 1992, U.S. Coast Guard pilots reported an ash cloud to 1200 m above Pyre Peak and extending 24 km north. Intermittent, localized bursts of ash rising 100-200 m and ash accumulation on the south flank were observed on December 30. The vent was confirmed to be a satellite cone located 1.5 km south of Pyre Peak at the north end of a fissure that produced lava fountains in 1977. The activity apparently subsided soon thereafter. No subsequent activity ... More information | exclamation.png | ye | 50 | http://www.avo.alaska.edu/volcanoes/activity.php?volcname=Seguam&eruptionid=88&page=basic | |
| 1993-05-28 | 1993-8-19 | Pyre Peak: 1993 | From Miller and others (1998): "Explosive ash eruptions along with a lava flow were reported by Coast Guard observers from July 31, 1993 through August 19, 1993; ash clouds were reported to altitudes of 2,500 m at times during this interval."
However, eruptive activity was reported from Seguam as early as May 28. 1993, and this may be the start of this eruption (Smithsonian Institution, 1993): "A small ash burst, rising through clouds near Pyre Peak, was reported by the U.S. Coast Guard on ...
