>2. I'm quite certain that the "side vent" described with this activity is/are the same as what I put into my book's 4th Edition as "UNNG-MGG-2 ("Sentinel's Vents")". The >eruptions I saw in 2004 and 2005 were independent of anything more than the normal boiling in East Sentinel itself. As I said before, the side vent I am talking about is actually in the channel that flows between East Sentinel and the embankment. I have attached some pictures to show its location. You can also see it on the YouTube video Dave Monteith posted. If "Sentinel's Vents" participated in the eruption, it was before I arrived at the scene. Clark Murray and David Schwarz have both reported that they did not see this vent erupt when they witnessed eruptions of East Sentinel in 1991 and 2001, respectively. I didn't get a year for the eruption Mike Keller saw that included the side vent. I believe this is the vent described as a drain hole by Murray. --Tara Cross fanandmortar at hotmail.com -------------- next part -------------- An HTML attachment was scrubbed...
