A magnitude 7.5 earthquake struck northern Japan, triggering initial tsunami warnings that have since been downgraded. Residents reported a 'low rumbling' sensation as the quake hit, leading to heightened concerns over potential aftershocks.
Authorities are advising people to carry emergency supplies for at least a week, following a 'mega-quake' warning. The situation remains fluid as officials continue to assess the impact of the earthquake and monitor the region for further developments.
