After the earthquake in March 2011 changed the status of water in the Japan Trench

May 30, 2013. A survey conducted by Japanese scientists found that the water in the Japan Trench was troubled by the earthquake that struck northeastern Japan in March 2011, according to NHK.

The researchers from the Japan Agency for Marine-Earth Science and Technology have used a special camera to explore the deep-water areas near the epicenter of the quake.

They found that even 4 months after the earthquake, sediments still circling above the bottom is about 110 kilometers south-east of the focal zone.

Usually the seabed at a depth of 7,000 meters calmer with weak currents. The researchers attribute the unusual status with a series of aftershocks that followed the massive earthquake.
