Waves in lakes make waves in the Earth

Scientists at the University of Utah report that small seismic signals emanating from lakes can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over and when it thaws. And as a small, constant source of seismic energy in the surrounding earth, lake microseisms can shine a light on the geology surrounding a lake.
