It turns out that there is a remarkable correlation between the intensity of earthquakes and cosmic rays, and there is also the possibility that it can be applied to predict the occurrence of earthquakes
Earthquakes sometimes cause great human damage and economic loss. Therefore, technology to predict when and where earthquakes will occur is being researched on a daily basis. The Institute of Nuclear Physics, Polish Academy of Sciences (IFJ PAN) has shown that there is a correlation between cosmic rays and earthquakes, and that it is possible to predict earthquakes by observing the intensity of cosmic rays.

Dr. Piotr Homola, IFJ PAN scientist and coordinator of the CREDO project, said, 'The idea of a link between cosmic rays from the sun or deep space and earthquakes may seem strange at first. The physical basis is perfectly rational,' he commented.
According to the research team led by Dr. Homola, eddy currents occurring in the outer core of the earth, which is composed of liquid metal, are involved in the generation of the earth's magnetic field. In other words, the research team argues that the internal movement of the earth related to earthquakes changes the earth's magnetic field, and the change in the magnetic field affects cosmic rays.
The CREDO (Cosmic Ray Ultra Dispersive Observatory) project, which IFJ PAN has been promoting since 2016, collects data not only from advanced scientific detectors, but also from small detectors such as CMOS sensors installed in smartphones. , to check changes in cosmic rays. Analysis of the data collected in this project revealed a clear correlation between changes in the intensity of cosmic rays and the magnitude of earthquakes of magnitude 4 or higher. Cosmic ray fluctuations were observed about 15 days before the occurrence of the earthquake, so the IFJ PAN research team points out the possibility of predicting earthquakes from cosmic ray observation data.
Dr. Homola said, 'In the world of science, it is said that a discovery is made when the standard deviation of the supporting data reaches 5. 6, and the probability of this correlation being the product of chance is less than 1 in 1 billion, so we have statistical grounds for claiming that there is a correlation between cosmic rays and earthquakes. It was.”
However, we can only predict when an earthquake will occur, and we cannot predict where it will occur. Also, it should be noted that we can only predict when cosmic rays occur, and when the scale of the earthquake affects the entire earth.
In addition, it is said that the correlation between cosmic ray data and earthquake data has a periodicity of 10 to 11 years. This periodicity is similar to the cycle of solar activity. Furthermore, we found that the seismic activity and the intensity of cosmic rays change with a period corresponding to 23 hours, 56 minutes and 4 seconds, which is the sidereal day of the Earth. From this, it is possible that the correlation between space and earthquakes is caused not only by problems inside the earth but also by some factors arriving from outside the earth. However, it is unknown at the time of writing the article what kind of physical phenomenon causes such periodicity.
'Whatever the cause of the observed periodicity, the most important thing at this stage is that we have demonstrated a link between recorded cosmic rays and seismic activity on Earth,' said Dr. Homola. If there is, it means that this observation points to a completely new and exciting research opportunity.'
