Less than few hours, Tsunami swept metropolitan Japanese cities into the influx of dumpsters. However, Tsunami not only brought changes in the sociocultural geography in Japan but also the global geographic shift.

As a result of unprecedentedly massive Japanese Tsunami, the axis of rotation moved 16.5 cm and earth’s rotation velocity became 1.8 second per 100 million minute faster. Even the nearest neighbor, Korea has been shifted at least 5 meter to the Pacific Ocean. Due to Korean shift towards east, the risk of crash between Korea and Japan escalated.

Based on the prior experience of geographic shift caused by San Francescan and Chilean earthquakes (which moved the globe 2 meters), scientists are paying attention to the subtle movements in East Asia to prevent collision between continents and prospective problems in shifted countries.
