Solar Activity and Electromagnetic Signals that preceded the M7.5 Earthquake of January 1, 2024, in Japan.

On January 1, 2024, a strong earthquake occurred in Japan, causing deaths and damage to Japanese infrastructure. This study discusses the electromagnetic and solar signals that anticipated the strong earthquake. This earthquake was preceded by a series of electromagnetic signals recorded by the RDF network developed by the Radio Emissions Project in Italy and by peculiar solar activity that occurred in the days before the disastrous quake. The authors believe that there may be a relationship linking telluric activity with space weather, evidenced by electromagnetic signals detectable in the phases preceding the earthquake in a time window of about five days. The results of the experiment show that the data can be compared with other known cases in the scientific literature, in the context of a crustal diagnosis and seismic precursor candidates.
