Anyplace that has so many steam vents and boiling mud pits and geysers should never be allowed to be geologically active. That's just looking for trouble.

Take a look at the land mass that is the Yellowstone "Valley". There is a great valley that exists from Yellowstone all the way to the east coast. Geology experts have theorised that the Yellowstone "Event" is a deep volcano underneath the land mass that has been active for may million years, and the continental drift of the Teutonic plates has dragged America along over the top of the super volcano that is underneath that. Thus, the Yellowstone is its own "Skid mark" over the landscape, and that great valley of geology that goes east, is the remains of regular "events" of Yellowstone, as the volcano continues to erupt as the American land mass travels ever so slowly [about 4 inch per year?.. ] eastwards over the top. If you live on the west side of Yellowstone... expect super-heated "free" underfloor heating in the future at least?... See below, the "Yellowstone Caldera chain" as an indication of what I mean, Yellowstone appears to be moving east-west, its not, its the land mass moving west>east over the top of the main caldera many many many miles below.  |

the land is moving to the west - the hot spot appears to be moving east.
and yes, sometimes the weak spot moves with the land, and sometimes the weak spot is no longer over the hot spot tht caused it to punch through, and it ceases to be active. a caldera requires a minimum of two eruptions to form - the first to build the mountain and the second to blow the top off of it.
