Certainly something to keep an eye on. Because if it does erupt with full force, then it could affect a lot of Americans.
My theory is based on the pressure being distributed over time versus all at once. The underlying activity is important. It depends on why there are no earthquakes. Is it because it is building up? Adding and accumulating? Or is the underlying activity slowing down.
In this context earthquakes are related to the movement of magma. No earthquakes = no movement of magma = good.
On the other hand, the existence of these earthquakes = movement of magma = bad.
Now Yellowstome has a lot longer time period between eruptions, so the movement of magma can continue for a very long time before it’s finally filled up to “exploding time”.
We would prefer NO EARTHQUAKES in Yellowstone, as the perfect state of being. However, that doesn’t look like the cessation of earthquakes is going to be the situation - and thus - we are BUILDING UP (by all these earthquakes) to the BIG EXPLOSION.
