A team of researchers may have discovered a way to hear earthquakes. Not the noises of rattling windows and crumbling buildings, but the real sounds an earthquake makes deep underground as rock grinds and fails catastrophically. Typical seismic waves have frequencies below the audible range for humans, but the August issue of EARTH shows you where to find the voice of one seismic monster: March 11, 2011, magnitude-9.0 Tohoku earthquake in Japan.
