Seismic waves of a M4 earthquake about 30 km from Nagoya, Japan, recorded in Inuyama, a small town near Nagoy, at seismometer INU (Geoscope network), and sped up 100 times: one second audio is about 2 minutes in the data.
You can hear that two wave trains arrive in rapid succession: probably the P-wave first (compression wave) and the S-wave after, accompanied by a small amount of surface waves.

Sonification method:
A seismometer (seismic station) records ground velocity in time. This data can be turned into sound by speeding it up, as ground motion is usually in infrasonic frequencies. Most seismic data can be freely (although not easily) downloaded from https://service.iris.edu/fdsnws/dataselect/1/.
