In a general way, I believe so, especially if it's caused by magma intrusions (magma suddenly filling up empty cracks in the rock). That's virtually
the definition of a volcanic eruption: a magma intrusion that suddenly breaks through to the surface. But if it's just fault lines grinding together,
or hot water getting pushed around, it's nothing to worry about in an eruptive sense. Unless the water flashes into steam while trapped underground,
in which case it'll make its own hole to the surface very quickly. Hydrothermal eruptions have always been fairly common at Yellowstone, though.
Again, too many variables.
The one sign that I would truly watch for is harmonic tremors, caused by magma shooting through cracks in the bedrock and making it vibrate. Magma on
the move is the real worry, even if it doesn't "erupt." The caldera is covered with lava flows from only a few thousand years ago, when there was
no eruption. It just leaked a lot, but slowly. If that happened now, it'd probably entomb the park, but the rest of the world would be just fine.
We just don't know, in brief. We have no observations of similar events to go on. We only know that, if it erupts suddenly, the bottomless pit of
fire will open up and the sun will turn black and the moon will turn to blood and the sky will be filled with "falling stars" and a third of the
plants and animals could die and there'd be starvation and strife and conflict and- why does this all sound familiar... something about a sixth seal
or something...
Hm.
