Electromagnetic anomalies occurring before large earthquakes

Electromagnetic anomalies occurring before large earthquakes

A new study published in Earth, Planets and Space sheds new light on the electromagnetic anomalies occurring before large earthquakes. The research supports the hypothesis that fault rupture progresses just before an earthquake, and the invading gas is charged and forms a large current, causing various electromagnetic anomalies.

It has been documented over hundreds of years that various electromagnetic anomalies occur a few weeks before the occurrence of a large earthquake. These electromagnetic anomalies are variations that appear in telluric current, geomagnetism, electromagnetic waves, etc. before the earthquake, authors of the new study say.

Although there are various models to explain the mechanism, the large current generated at the source was not fully explained.

For example, many researchers thought that the stress applied to the fault produced an electric current, but the stress applied to the fault takes place over hundreds or thousands of years before the occurrence of the earthquake.

It is a common belief among seismologists that it is impossible for the stress to suddenly increase and generate a large current just before the earthquake, and therefore the mechanism had not yet been explained.

To resolve this mystery, Shinshu University and Genesis Research Institute, Inc. conducted a joint research project on earthquake-preceding phenomena under the leadership of Professor Emeritus of Shinshu University, Dr. Yuji Enomoto. The research group made the following hypothesis and conducted laboratory experiments on indoor rock fracture and gas-electric interactions to solve the mystery of electromagnetic anomalies.

In the area that is at the epicenter of a seismic fault, a fault-valve forms before the next earthquake occurs. It is believed that dense layers in the crust are formed over time. The fluid, including some gases such as water that springs up from the vicinity is trapped by the fault valve and stays there. When the shear stress applied to the fault or the pressure of the stagnant reserved fluid reaches criticality, the fault valve cracks, the high-pressure fluid rises along the fault, and the pressure gradually decreases.

As the pressure decreases, carbon dioxide or methane that are now dissolved in the fluid are degassed at once, expanding in volume and expanding the cracks. The model considers the fault becomes fragile and the rupture accelerates, leading to an earthquake. The gas becomes electrified in the process. That is, it is charged with electricity. The trapped electrons in the defects are suddenly released due to the thermal stimulus and attached to gas molecules. Because it is negatively charged, a current is generated as the gas moves.

In the lab, several types of rock, including granite, gabbro, quartz diorite and basalt were tested. A simple estimation found that there is a high possibility that a large current will be generated immediately before the earthquake, depending on the earthquake magnitude.

This supports the above-mentioned hypothesis that fault rupture progresses just before an earthquake, and the invading gas is charged and forms a large current, causing various electromagnetic anomalies. In the future, the group plan to carry out field observations to verify this model.

In the coupled electric interaction of rock fractures and gas invasion, that is, when gases interact with newly created crack surfaces, the unpaired electrons within the rock crystal defects are thermally stimulated, released into the crack due to the temperature rise at the crack tip via plastic work, and attached to ambient gas molecules to electrify them in a negative state. Using a working hypothesis that this mechanism is the source mechanism of seismo-electromagnetic phenomena, we conducted laboratory experiments in which rocks were fractured with pressurized N2, CO2, CH4, and hot water vapour. Fractures were induced by a flat-ended indenter equipped with a flow channel, which was loaded against blocks of quartz diorite, gabbro, basalt, and granite. Fracture-induced negatively electrified gas currents at ~ 25 °C and ~ 160 °C were successfully measured for ~ ≥ 100 μs after full development of the crack. The peak electric currents were as high as 0.05–3 μA, depending on the rock species and interaction area of fractured rock and gas and to a lesser extent on the gas species and temperature. The peak current from fracturing granite, which showed higher γ-ray activity, was at least 10 times higher than that from fracturing gabbro, quartz diorite, and basalt. The results supported the validity of the present working hypothesis, that coupled interaction of fracturing rock with deep Earth gases during quasi-static rupture of rocks in the focal zone of a fault might play an important role in the generation of pre- and co-seismic electromagnetic phenomena.

Hello Jamal, Was most impressed with your dialogue on the reason for ocean tides not being a gravity effect but more a magnetic one. I am also a dissident of modern day science where I have proven the South Circle to be that of a Flat Plane and not that of a Globe. Are you familiar with the work of Ken Wheeler and his research with respect to magnetism and electricity in general and the two controlling forms of Transverse Electro Magnetic (TEM) flow and the second in the Longitudinal Magneto Dielectric (LMD)? https://ia802502.us.archive.org/31/items/magnetism1small/magnetism1small.pdf The TEM follows the wire loop where the LMD jumps across to the other side at a speed of Pi/2 - Tesla. There are no such things as 'electrons' nor of 'electron flow' but there is a Plasma which is the last matter state step to the Ether. I have the Dollard Cosmic Ray Detector (CRD) working here but is not as yet connected into any monitoring system due to time constraints as this is able to quantify the Cosmic intensity with respect a Solar Minimum and the activity level of Earthquakes and Volcanoes. You might like to comment on why we see a Sun Disc on the Earth surface via the Japanese Himawari-8 weather satellite and is it possible to correctly identify the Sun's position using this phenomena. http://satview.bom.gov.au/ Respectfully.

According to, my proposed Magnetic Structure of Matter, there is nothing new in this study. Magnetic interactions govern all physical processes and phenomena in the Earth's atmosphere, on Earth's surface and at the Earth's interior. When magnetic radiation reaches the Earth, it can be reflected, absorbed or transmitted. In other words, when magnetic radiation reaches the surface of the Earth, different types of interactions are possible depending on the intensity of the radiation (the wavelength of the energy), the surface materials and the geometry of the surface. However, regarding the correlation between earthquakes and electromagnetic anomalies, I have to emphasize that the anomalies occurring first at the magnetosphere and the driving force behind the anomalies is the solar-cosmic radiation. Thus, in order to explain the anomalies, the mechanism of energy transfer from the magnetosphere to the ionosphere has to be understood

Thanks for the clarification. Regards.
