A series of strong earthquakes have recently shaken various regions in Japan, with the most significant being a magnitude 5.7 quake that struck central Japan, injuring at least 22 people and shattering store windows. This seismic activity is part of a pattern that includes a 6.1 magnitude earthquake off the coast near Tokyo, which prompted a tsunami warning despite no major sea level changes reported. Over the past month, Japan has experienced multiple earthquakes, including a 5.4 magnitude quake offshore Ibaraki Prefecture and a 5.6 magnitude tremor off the coast. Rail and airport services have been disrupted due to the ongoing seismic activity.
