[Geysers] Loud Steam Phases

[David Monteith]

Jeff:

During one April 1994 eruption of Dark Cavern, I met visitors that had
heard the steam phase from Green Dragon Spring and were intrigued enough
to search for the source of the noise.  

As for Ledge, I do not remember it being as loud as Dark Cavern.  It was
easily audible from the parking lot (very depressing after a 7 hour
drive, but audible.)  I missed the early 1994 eruptions that were
reportedly stronger than the later eruptions that I saw and heard.
Don't get me wrong, the later eruptions were very impressive, too.

Similar figures can be obtained for other geysers.  However, I cannot find data for the following geysers:
