Japan's meteorological agency has issued a warning of a heightened risk of a major earthquake hitting the country in the near future, following a 7.1-magnitude temblor off the southern island of Kyushu. The earthquake has raised concerns about the potential for a devastating Nankai Trough megathrust earthquake, which experts warn could cause widespread destruction, tsunamis, and loss of life. The agency has urged residents to be prepared for potential evacuations and to remain vigilant for aftershocks. While the recent earthquake resulted in some injuries and a tsunami advisory, damage was minimal, and operations at the affected areas have since resumed. The government is on high alert, and the public is advised to stay cautious in the coming days.
