AI Thread Summary
A significant earthquake measuring M 7.1 struck the Hyuganada Sea near Japan on August 8, 2024, at a depth of 25.0 km. This event has been followed by an aftershock of M 5.4 located 7 km WSW of Miyazaki, occurring later the same day at a depth of 19.5 km. Additional aftershocks ranging from magnitudes 4.3 to 4.8 have also been reported. Experts express concern that the M 7.1 quake may be a precursor to a larger seismic event, prompting the issuance of Japan's first-ever megaquake warning. The situation is being closely monitored as the potential for further significant seismic activity remains.
