Interesting,
The earth is still rebounding from the Ice Age layer of snow.

Just a thought on the timing of this drill. When the local river 2 miles east of me floods I get definite tilt in that direction.
Could there be any increase in risk caused by the record flooding on the Mississippi? There will be saturation of the ground and a
huge mass of water rolling across the area creating a dynamic load.

Randy,
Your comment is interesting. About two weeks ago I noticed my Lehmans were not displaying data as I expected. (see last 2
posts-Evansville,IN). The backwaters of the Ohio were within about 1000ft of my house; and of course, the flooding made national
news. This ended a 2 year regional shortfall of rain. My basement sits below the surface level of a small lake (50 ft from the
house) and I thought the floor was flexing --- either from the house floating or seasonal temperature changes. I never expected the
possibility of a regional effect.
