Funny you should mention Laplace. I used to work on earthquake prediction research in which we used groundwater levels in deeps wells to measure earth strain. If the strain changed anomalously, the groundwater would rise or fall, and an earthquake would soon follow. That's the theory, anyway.
Because of earth tides, groundwater rises and falls twice a day as the earth compresses and contracts. To filter out these earth tide effects, we modified the data with a Laplace Transform.
