this steam pipe eruption. I’m referring to the most powerful time in
the steam phase, in the immediate aftermath of the transition from water

<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>Steamboat
Geyser is generally acknowledged to have the most powerful steam phase of any
geyser in <st1:place w:st="on">Yellowstone</st1:place>, with Giantess often
being cited as the second most powerful. But how could the power of the
steam phase be quantified? Perhaps we might compare it to an event about
which some parameters are known:<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>I
found the following footage of the 2007 <st1:City w:st="on"><st1:place w:st="on">New
York City</st1:place></st1:City> steam pipe explosion. The pipe was 24
inches in diameter, and carried steam at temperature of 400F. The steam
cloud rose to a height of the nearby <st1:place w:st="on"><st1:PlaceName w:st="on">Chrysler</st1:PlaceName>
<st1:PlaceType w:st="on">Building</st1:PlaceType></st1:place>, which is just
over 1000 feet high. The crater left by the explosion was 35 feet wide
and 15 feet deep.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>Would
anyone who has seen Steamboat be willing to rate the power of the eruption in
the film referenced below, and indicate whether it is more powerful or less
powerful than the steam phase of Steamboat Geyser? (Or perhaps, Giantess
at its best.)<o:p></o:p></span></font></p>
