It was a very noisy, and shaky night here in beautiful downtown Clintonville, Wisconsin where noises, noises, noises have been being reported over the last couple weeks and it was determined along the way that it was geological in nature!
There was a lot of small ground rumblings throughout the night and up until around 1 am and past that before I actually heard anything that might have been blamed on the movement of large geological fragments underground. There was one fairly large and reletively short one followed by a quick bump around 2, but that was pretty much it. Thought that while it had been much colder at the end of the day yesterday, and now headed up to the 60's that the coldness contracting, and incoming warmth expanding might be to blame for a little plate tectonics happening there.
Finally a quick close inspection of their downtown area along the Pidgeon River, that I can actually see out the window of my motel, I noticed that each of the 4 road bridges and 2 walkway bridges all seem to show signs of very minor "Pull-Apart" movement. Got some pics and measured with a folded dollar bill and came up with around .010 to .035 inches throughout the downtown area which had been well reported as more or less the exact epicenter of all the shaking.
Notice how clean and sharp these brand new cracks are! There are many and they are CONSISTANT throughout these downtown bridges. Seemed obvious they couldn't be more than a couple days old, here! Some day one side of this river will be Japan, the other side California! Look sort of like the beginning of the next San Andreas Fault, am I right?
Today, there is like one more foot bridge to check out, and it looks like the sun will be coming out so probably some Rollerblading, too! Thank-You for Reading! Quake Chaser / EQ Guy
