 the earthquake foci, the center where the earthquakes begin, gets progressively shallower. Now, I don't know a lot about what you're talking about, but I know that if the ground began to swell, that's really bad. Yeah. Really bad. And it was doing that 10 years ago, I guess 1980, when they had a series of six-magnitude quakes at the same time as Mount St. Helens erupted. And I think there was some relationship there.
