SUMMARY

The M7.1 earthquake that struck the Hyuganada Sea off the eastern coast of Kyushu, Japan, on August 8, 2024, has raised significant concerns regarding potential larger seismic events. The quake occurred at a depth of 25.0 km and was followed by an aftershock measuring M5.4 near Miyazaki, Japan. Additional aftershocks ranging from magnitudes 4.3 to 4.8 have been recorded, prompting experts to consider the possibility that the M7.1 event may be a precursor to a more powerful earthquake. Reports from various news outlets highlight the urgency of monitoring the situation closely.
