Short summary
A semiconductor model of rocks is shown to describe unipolar magnetic pulses, a phenomenon that has been observed prior to earthquakes. These pulses are suspected to be generated deep in the Earth's crust, in and around the hypocentral volume, days or weeks before earthquakes. Their extremely long wavelength allows them to pass through kilometers of rock, and the source of the pulses may be triangulated to pinpoint locations where stresses are building deep within the Earth.
