Japan's Shizuoka magnitude 5.7 earthquake Meteorological Agency analysis: "low correlation" with the Nankai Trough

An earthquake with a magnitude of 5.7 occurred in Shizuoka Prefecture, Japan in the early morning of today (8th). The maximum intensity of magnitude 5 was observed in many places in neighboring Aichi Prefecture. This was the first time in nearly 30 years that the county experienced an earthquake with magnitude above 5. The local disaster was even more serious than in Shizuoka Prefecture. Since the epicenter of this earthquake is located in the predicted source area of ​​the "Nankai Trough Giant Earthquake", many people are worried that it is a precursor to a giant earthquake. The Meteorological Agency held an emergency press conference to explain, emphasizing that the correlation between the two is low.

Comprehensive Japanese media reports, according to observation data from the Japan Meteorological Agency, the epicenter of the magnitude 5.7 earthquake that occurred early this morning was located in the western part of Shizuoka Prefecture. The Meteorological Agency reminded that in areas affected by strong shaking, the risk of rockfalls and landslides has increased significantly, and that people must pay close attention to the possibility of an earthquake with magnitude 5 in the coming week.

Reports pointed out that the epicenter of this earthquake happened to be within the expected epicenter of the "Nankai Trough giant earthquake", causing people from all walks of life to be very worried about whether it was related to the Nankai Trough giant earthquake that the Japanese government had repeatedly warned might occur in the next 30 years, with an earthquake magnitude of about 8 to 9. There were also a lot of earthquake disaster discussions on social networks, and even went viral saying "the scale of the Nankai Trough giant earthquake is about 125,892 times that of this earthquake", making the public worried.

Ayaki Ebita, section chief of the Earthquake and Volcanology Department of the Meteorological Agency, explained at the press conference that although the earthquake occurred within the predicted source area of ​​a huge earthquake in the Nankai Trough, the focal depth and mechanism of the earthquake are different, and according to monitoring data, there is no obvious abnormality in the plate boundary state. It is judged that the correlation between this earthquake and the huge earthquake in the Nankai Trough is low, but the public is still reminded to pay attention to the recurrence of earthquakes of the same size in the next week.
