Trident reported activity



Event Name : Trident 2005/6

Start:June 2005 ± 2 YearsObserved

Seismicity with no confirmed eruption: BibCard
Eruption Type:Not an eruption.

Description: From McGimsey and others (2007): "AVO Coordinating Scientist John Eichelberger was leading an annual student fieldtrip into the Valley of Ten Thousand Smokes (VTTS) in June 2005 when, from the rim of Trident Volcano, he observed a new crater about 50 m (165 ft) in diameter. Eichelberger has traversed the VTTS for many years and verified that the crater was not present during his 2003 trip; clouds prevented viewing the area of the crater in 2004. Although no anomalous seismicity was noted in the Katmai area in 2003 and 2004, a period of tremor-like signal occurred in the Katmai area on April 27 as noted in the AVO Seismic Logs. No correlation has been determined."
