SOUNDS OF SEISMOLOGY
This website / exhibit, "Sounds of Seismology", is about earthquakes and the physics of the Earth, using images and sound to illustrate concepts and raise questions.
Here is an example of a direct sound of an earthquake, recorded in Friuli, Italy on May 6 1976, from a compilation by Karl Steinbrugge (U.C. Berkeley):



When we say "Sounds of Seismology", we are not talking about these sounds; we are talking about a very different thing:
We are taking data from seismometers, recording waves in the Earth with much much lower frequencies than we could possibly hear, and shifting them to frequencies in the range of our hearing. The sounds convey meaning that we can interpret with physical intuition, which can be translated to an understanding of the Earth and inevitably leads to more questions...
