One of the important aspects of the monitoring equipment
is to be able to give scientists the ability
to predict in advance when an eruption
is going to occur.
And in it's simplest form,
the larger the potential eruption,
the more molten rock that's coming up
over a greater area,
the more signals that will occur.
The more earthquakes that will occur,
the larger the area affected,
the more the ground deformation will be occurring
in that area,
and the more there'll be changes
in the thermal system, in gases.
So, the larger the eruption,
the more advance notice there'll be,
and the smaller the eruption,
the less advance notice.
But that's the way we would hope it would be
because the smaller the eruption,
the less the effect of it
to Yellowstone or even to smaller areas
