Recent seismic activity has rattled Japan, with several significant earthquakes reported off the northern coast. A magnitude 7.5 quake injured over 20 people and triggered a small tsunami, prompting the government to issue evacuations and tsunami alerts. This was followed by additional quakes of 6.7 and 6.9 magnitudes, leading to concerns about potential megaquakes that could have catastrophic consequences. In light of these tremors, authorities are actively monitoring the situation and have lifted tsunami warnings as conditions stabilize.
