Using Electromagnetic Energy from Unipolar Pulses Released prior to Earthquakes to Obtain Images of the Subduction Zone in Central Peru.
Abstract
Since April 2013, we have been collecting and presenting outstanding evidence that the ULF pulses received by a network of 10 magnetometers along the central and southern Peruvian coast, are indeed connected with earthquakes that develop in the subduction zone along the western coast of South America. After computing azimuths of occurrence of such pulses, around individual magnetometers, triangulation of two such stations conducted to the two-dimensional determination of possible epicenters.
However, it was the three-dimensional image of the occurrence of such pulses that gave the assurance that every single point of origin of the unipolar pulses detected prior to an earthquake is located in an inclined plane, with the appropriate angle constituting a three-dimensional image of the Benioff zone, the interface plane between the two meeting tectonic plates. Lately, additional work has been carried out that shows in a very evident way that electromagnetic energy at the source of unipolar pulses is being released all the time and constitutes a discrete but permanent process that eventually builds up into a seismic event. It turns out that not all of the EM activity translates into seismic events, at least detectable ones, so this explains some cases of false positive events and rather than random errors they become systematic errors that need to be resolved. This adds new interest in the process and a path to a better understanding of the physics of the subduction zone. Dynamic images of the energy released will be presented in time lapsed video form depicting how the effect builds up to constitute an earthquake, reinforcing the concept of pre-earthquake prognosis based on physical phenomena conveyed by electromagnetic waves.- Publication:
