This omnipresent seismic noise is also a big challenge for building terrestrial gravitational wave detectors like LIGO. Even though the noise is "only" a bunch micrometers of movement, they had to deploy multiple levels of noise suppression to be able to measure gravitational waves: https://youtu.be/j4gE-hSQm68?t=1380 https://youtu.be/j4gE-hSQm68?t=1380
