A 7.5 magnitude earthquake struck the eastern waters of Aomori Prefecture in Japan late on the night of the 8th. Japanese experts said that this was a typical earthquake that occurred at the boundary of a geological plate, and the mechanism of occurrence was similar to the 2011 Great East Japan Earthquake. According to information released by the Japan Meteorological Agency, the epicenter of the earthquake was located about 80 kilometers east-northeast of Hachinohe City, Aomori Prefecture, and the depth of the earthquake was 54 kilometers. Kazunari Ohara, the former president of the Seismological Society of Japan, said that the Aomori earthquake was a typical Itaman earthquake. It was caused by the subduction of the Pacific plate on the ocean side to below the North American plate on the land side, making the landside plate unable to withstand the strain. Earthquakes are divided into interplate earthquakes that occur at plate boundaries, intra-plate earthquakes caused by fracture activity within plates, etc. The mechanism of occurrence of this earthquake is similar to the magnitude 9 Great East Japan Earthquake that occurred in 2011. Japanese experts are generally concerned that a major earthquake may occur in the South China Sea Trough in the Pacific Ocean in the eastern Pacific region of Japan in the future due to the same mechanism.
