[O08-P19] Earthquake prediction by electromagnetic waves ⅤｰAchieving disaster mitigation by detecting signs of damaging earthquakesｰ
Keywords:Earthquake prediction, electromagnetic wave sign
1. the purpose
It captures electromagnetic radiation, which is considered a precursor to earthquakes, and makes it possible to predict earthquakes. By observing electromagnetic wave radiation using precursors, we can predict earthquake magnitude and earthquake occurrence areas based on the relationship between signal strength, duration, and radiation direction data. Make it possible to detect precursory phenomena associated with damaging earthquakes using continuous observation methods. Introducing AI (artificial intelligence) to quickly detect warning signs.
2. Method
VHF band receiver continuously records the signal strength of electromagnetic waves radiated from the ground surface to the atmosphere. The antenna will be installed at a height of 17m and will be used to pinpoint the area where the incident occurs using both omnidirectional and directional antennas. A comprehensive judgment is made, including signal strength data, lightning data, ionosphere data, etc., and it is determined as a sign of an earthquake. It will also detect characteristics of observation data that occurred before the Great East Japan Earthquake. The hypothesis is that the precursory phenomenon is not an electromagnetic phenomenon that occurs only near the epicenter, but rather occurs in a shallow region of the earth's surface due to stress on the earth's crust due to plate movement.
3. result
It has been 11 years since our school began observing electromagnetic phenomena that occur before earthquakes. Observations are continuing in line with previous research. JR East's Chuo Line runs close to the observation site, making it difficult to determine if it is a small-scale warning sign. Compared to the data for Shinjuku Ward in the previous study, many of the high-level signals are consistent. Shinjuku observation data will also be used to capture precursory phenomena. A precursor phenomenon appears as a phenomenon if the epicenter is within the depth range of 20km to 90km. If the magnitude is large, there are signs even at a depth of over 100 km. AI was used to detect electromagnetic waves caused by lightning and compared with lightning occurrence data.
4. Consideration
In this study, the only event in which we were able to observe the maximum value of electromagnetic radiation at the same time as the earthquake was the 2015/9/12 Chofu seismic intensity 5+ earthquake . If the piezo effect were to be used alone, it would definitely be detected when an earthquake occurs, but there are only a few cases where it is detected. Data from the Shinjuku observation point during the Great East Japan Earthquake show that the signal level, duration, and frequency of normally occurring electromagnetic radiation differ greatly. The theory is that the movement of electrical charges and noise caused by discharges emanating from near observation points or near the earth's surface, such as from active faults in areas where radio waves can be received, appears as a sign of an earthquake.
5. conclusion
We would like many researchers to carry out observations using current observation methods in order to confirm the hypothesis, identify the area where the signal occurs, and realize disaster mitigation and prevention.
