caldera management: lake yellowstone

put a huge circular dike around yellowstone park, fill with water, lake yellowstone, you lose a beautiful park, but maybe save the human race for the billions of tons of water will possibly keep the hatch on this pressure cooker and prevent catastroph of biblical proportions from happening....

If the caldera blows anyway, the 45 degrees sloped and concrete plated dikes will reflect schokwave upward and the water catch many fine dust that otherwise would put earth in dark nuclear winter like conditions.

Put some windmills on top of the high dikes to make some good use of the elevated windspeed during peacetime, perhaps the lake could be coupled with the windmills for pumped storage / peak grid usage buffer.

Develope fish farms and watersports...
