Earthquake Kyoto University Disaster Prevention Research Institute analyzes whether a “residual earthquake crack area” exists in the Hyuga-Nada Sea， and whether there is a possibility of another M7 earthquake occurring．
Analysis by the Miyazaki Observatory of the Kyoto University Disaster Prevention Research Institute has revealed that areas that were not destroyed by the magnitude 7.1 earthquake that occurred in the Hyuga-Nada Sea on the 8th are believed to be located under the seafloor of the Hyuga-Nada Sea. They are calling for caution as there is a possibility of another magnitude 7 earthquake occurring in an area several tens of kilometers northeast of the current epicenter. The Hyuga-Nada Sea is located at the western edge of the predicted focal zone of the Nankai Trough earthquake, and earthquakes frequently occur where part of the boundary between the oceanic and land-side plates breaks and shifts. Assistant Professor Hiroaki Yamashita (observational seismology) of the observatory conducted the analysis based on the results of analysis by the Geospatial Information Authority of Japan and others. It was found that there is a high possibility that the cracking of the plate boundary had not progressed in the area northeast of the epicenter of this earthquake. In roughly the same area, earthquakes of magnitude 6.9 and 6.7 occurred in October and December 1996, respectively, with the remaining fractures from the first earthquake rupturing two months later, causing a subsequent earthquake. Also, on the 8th, a 50-centimeter tsunami was observed at Miyazaki Port (Miyazaki City), but since the area where the rift remains is located shallower than the epicenter of this earthquake, there is a risk that a larger tsunami could occur if an earthquake of magnitude 7 or higher were to occur. Assistant Professor Yamashita said, “Because this is part of the earthquakes occurring in the Hyuga-Nada Sea, we don’t think there is a high risk of it causing a Nankai Trough earthquake, but it’s still necessary to prepare for earthquakes even after the response period for the emergency information has passed.” [Yomiuri Shimbun] 2024/8/12 (Mon) 9:30.
>>12 Recent research has shown that when the epicenter shifts, it’s almost certain that the main shock will occur beyond that. It’s not an occult thing, so you should research it yourself and take measures yourself.
Niigata is also under a lot of threats, with the remains of the Noto earthquake off the coast of Sado and a new fault line capable of causing an M8 earthquake having been discovered on the Toyama side. I think I’ll die of shock the next time the emergency earthquake alert goes off lol.
There is a blank area in the Hyuga-Nada Sea directly south of the epicenter of this earthquake, and there is an abnormal epicenter area to the southeast, which has led to emergency information, but we should stick to the Hyuga-Nada Sea and stop including the Nankai and Tokai Seas in the area.
Looking at earthquake data over a 100-year period, there are 20 times as many earthquakes in the Kanto to Tohoku area than in the Nankai Trough, so if you look around the Kanto Plain or Tohoku, you’ll probably find a lot of half cracks.

In other words, you should always be prepared for something like m7 to happen.

Well, it’s better to be prepared.

We survived 8/11, we’re safe now, disband.

>>39 You idiot wouldn’t understand, but we don’t have the technology to drill that deep. Plus, if we caused an earthquake of that magnitude, it would cause a chain reaction of larger earthquakes.
