In 2011, when Japan was rocked by 9.0 Tohoku earthquake, something strange happened 15 minutes later; scientists missed this deep-Earth process for more than a decade
A new study reveals the 2011 Tohoku earthquake triggered an extraordinary event deep within Earth. Seismic energy traveled to the outer core and bounced back, causing a massive, slow-moving slip along tectonic plate boundaries beneath Japan. This unprecedented event, missed for years due to its subtle nature, permanently shifted parts of the country eastward and highlights the far-reaching influence of powerful quakes.
