[Geysers] Photograph of Black Diamond eruption (Stephens)

[Freund, Udo]

Since GOSA seemingly can't do so, I think the best solution is to
request NPS via Hank to issue a statement correcting these erroneous
reports.  That is, of course, if they care to do so.
 
Let me get this straight, NPS Geologist, YVO Director and USGS folks saw
this and some took photos.  Whomever among these people issued the
"hydrothermal explosion" statement would have their bubble burst (pun
intended) by a retraction.

Thanks, 
Udo Freund 
The difficult we do immediately, the impossible takes us a little
longer, but performing magic is best left to professional magicians.

The photos are quite nice, but hydrothermal explosion?  I think not-the
photo looks like the eruptions of Black Diamond I saw in 2007 and
2008-muddy, filled with sinter, rocks, and lots of silt.  My impression
each time I have seen it is that there isn't much of a plumbing
system/geyser vent that the eruption is coming from.  Does that
constitute a hydrothermal explosion versus an eruption?  I would say
this is an eruption, especially since the area has a history of doing it
in the past 3 years, plus other events in the early 1910's, 1920's,
1930's, 1940's, and 1950's.  I would even dare to speculate that the
source of energy that drove Black Diamond/Wall Pool in these years moved
to Sapphire Pool after the 1959 earthquake and is just now returning
back to the Black Diamond area.

 

Maybe I am wrong, but my impression/definition of a hydrothermal
explosion is an area that has a large explosion or one time event, not a
history of eruptive activity.

Hydrothermal or not, that is the quesiton!

 

Isn't the assertion in the article that this was not a geyser eruption
but rather a hydrothermal explosion resulting in geologic effect similar
to the Pocket Basin explosion crater, Indian Pond or the Duck Lake
events?

Was this NOT a true hydrothermal explosion but just a "messy" geyser
eruption? 

 

 If it is a hydrothermal explosion, I have been informed that these
probably result  from a sudden drop in water pressure over the thermal
source. Did that occur at Black Diamond??

Need I point out the errors in this article. I hope the source wasn't
in-park... but as we all know, Black Diamond has had quite a few
eruptions... and above all, the statement that there are no geysers at
Biscuit Basin......... Well ?
