Researchers discover big cliff close to epicenter of 2011 Great East Japan Earthquake

A bunch of worldwide researchers together with Japanese professors says it discovered an enormous cliff in deep waters close to the epicenter of the 2011 Great East Japan Earthquake.

The group consists of scientists from Japanese and abroad universities and analysis institutes, together with Niigata University, and the Tokyo University of Marine Science and Technology.

In September final 12 months, the group used the manned US submersible Limiting Factor to discover the seabed about 7,500 meters deep within the Japan Trench, off Miyagi Prefecture.

The survey found {that a} almost vertical cliff with a top of about 26 meters was created close to the epicenter. The researchers additionally discovered that the encircling space was dotted with angular mud blocks, that are mentioned to be fashioned when mud accumulating on the seabed out of the blue collapses.

The group says such a topographic function was not confirmed when a special analysis staff performed a sonar survey in the identical space earlier than the 2011 earthquake.

The group put ahead the concept that the highly effective earthquake might have prompted a fault to slide deep underneath the seabed and transfer up about 60 meters, with the higher half believed to have emerged as a cliff.
