Earth's Core Reflections Caused Japan's 5mm Eastward Shift Post-2011 Tohoku Quake

An extraordinary seismic event occurred 15 minutes after the 2011 Tohoku earthquake, causing a significant geological shift across Japan. Waves reflecting off the Earth's core were identified as the cause of this unusual tectonic movement. This phenomenon resulted in nearly the entire country shifting approximately 5 millimeters eastward. The event highlights previously unknown interactions between seismic waves and the Earth's deep interior. Understanding these deep-earth dynamics is crucial for refining earthquake prediction and understanding tectonic plate behavior. This discovery offers new insights into the complex processes occurring within our planet.

This discovery reveals a surprising interaction between seismic waves and Earth's core, impacting geological understanding and potentially earthquake science.
