瀬戸内海で新たに活断層2本確認 M7以上の地震起こす可能性も

Researchers have identified two previously unknown active fault lines located within the Seto Inland Sea. Geological analysis suggests these structures possess the capacity to trigger seismic events reaching a magnitude of 7.0 or higher. Experts are currently evaluating the potential impact these faults could have on surrounding coastal regions. This discovery underscores the necessity for updated disaster prevention strategies in areas bordering the inland sea. Further investigation is expected to clarify the specific risks associated with these geological features.

The identification of new high-magnitude fault lines significantly alters the seismic risk profile for densely populated regions along the Seto Inland Sea.
