Earthquake precursors in the light of peroxy defects theory: critical review of systematic observations
Friedemann Freund, Guy Ouillon, John Scoville +1
The starting point of the present review is to acknowledge that there are innumerable reports of non-seismic types of earthquake precursory phenomena that are intermittent and seem…
Stochastic Time-Series Spectroscopy
John Scoville
Spectroscopically measuring low levels of non-equilibrium phenomena (e.g. emission in the presence of a large thermal background) can be problematic due to an unfavorable signal-to…
Paradox of Peroxy Defects and Positive Holes in Rocks Part II: Outflow of Electric Currents from Stressed Rocks
John Scoville, Jaufray Sornette, Friedemann Freund
Understanding the electrical properties of rocks is of fundamental interest. We report on currents generated when stresses are applied. Loading the center of gabbro tiles, 30x30x0.…
A Distributed Magnetometer Network
John Scoville, John Spritzer, Friedemann Freund
Various possiblities for a distributed magnetometer network are considered. We discuss strategies such as croudsourcing smartphone magnetometer data, the use of trees as magnetomet…
Pre-earthquake Magnetic Pulses
John Scoville, Jorge Heraud, Friedemann Freund
A semiconductor model of rocks is shown to describe unipolar magnetic pulses, a phenomenon that has been observed prior to earthquakes. These pulses are observable because their ex…
