Japan Earthquake Sparks Tsunami Alerts

A series of powerful earthquakes struck northern Japan, with a significant 7.5-magnitude quake injuring 23 people and causing a 2-foot tsunami. Although the initial tsunami warning was lifted, concerns remain over the potential for a 'megaquake' capable of triggering a devastating 98-foot tsunami, threatening up to 200,000 lives. Authorities are assessing the ongoing risks as travel safety is questioned amid these seismic activities.
