Also, just up the hill, Steamboat has become much more active over the past
few years compared to 8 - 12 years back

 From 1982-84, the last period of relatively short Steamboat intervals,
Echinus's interval was 50-60 minutes, with most eruptions having jets over
70 feet.  In 1984 it had "grand mal" eruptions that could last over an hour
and were very strong.  There's little evidence that a stronger Steamboat
somehow weakens Echinus.  They're clearly on the same fracture (if that's
the right word) mini-disturbances (called mini-zaps or (I swear to god)
"Gibbles" in 1984 affected Emerald, Steamboat and Echinus.  So they are
connected at some level.  The problem is correlating strong behavior in
Steamboat with weakened behavior in Echinus.  It's not really there, at
least in any statistically valid way.  Frankly, Echinus has been weakening
for years, with intervals lengthening, durations shortening, and the
strength of eruptions weakening.
