People around Lake Minnetonka have reported loud booms along with their homes shaking.
"Effectively, what's happening is you have frozen ground, because there's some water in the soil that freezes and the whole ground is frozen, and all of a sudden a crack forms really rapidly. When that happens, that releases energy that sometimes you can hear, and that's the boom. And sometimes it causes shaking," explained Lars Hansen, associate professor in the Earth and Environmental Sciences Department at the University of Minnesota.
