[Geysers] GSA article

[Paul Strasser]

For a market research (!) class I did a study to see if there was
statistical evidence of a beehive/OF connection. Nope.  A few years ago I
did one on my own for Castle and Grand.  Again, nope. 

 

And you saw Grand erupt from a completely empty pool - that is, it erupted
even before Grand reached overflow from the previous eruption. Dates and
times, please, because its interval would be completely out of whack with
t/e surrounding intervals. 

 

I agree with Scott to keep an eye on features near Grand, from Belgian to
Wave.  What to me was most amazing about the shorter intervals was the
narrowness of the eruption window.  After the five hour mark, the first fill
of grand that even looked semi -OK at the 12 minute mark would be the one.
Also\, its eruptions were tall, much taller than those before this fun time.

My father and I have seen Grand do some weird things. One observation was
that when Castle goes, Grand will follow. This happens between 60-75% of the
time and Grand has erupted from a completely empty pool at times for this.
Rick Hutchinson also noted it with my dad. This has lead to some spectacular
frames of Grand, Castle, Old Faithful, and Beehive going at the same time.
Once apparently Giantess joined in instead of Beehive.  
Dad and I have observed Grand erupting outside the normal window many times
over the years. I am personally all for the six hour window. Just means I
will have to pick now between it and Riverside. That is a toss up. 
Leads to fun questions like, "Are there actually any "normal" eruptions of
the big geysers really?" LOL. Food for thought.

So these guys believe that more YNP eruptions are possible but downplay the
possibility of a caldera forming super eruption?

 

And do you have any past history with Grand to speculate about the current
5+ hour eruption sequence. 

 

Chemo day one week from tomorrow. looking forward to getting it started.

I am taking some liberty in attaching an article published in the September
2012 issue of GSA Today. The title is "Future volcanism at Yellowstone
caldera: Insights from geochemistry of young volcanic units and monitoring
of volcanic unrest." Please do note that this article is under copyright by
The Geological 
Society of America and I pass this along for your reading only.
