I saw it in a thread yesterday with source but I couldn't find it today so I guess ignore it I posted a similar statement earlier in the thread maybe TA can help with this...
Dr. Daniel McNamara, a seismologist with the U.S. Geological Survey, told The Huffington Post that the disaster left a gigantic rupture in the sea floor, 217-miles long and 50 miles wide. It also shifted Japan's coast by eight feet in some parts, though McNamara was quick to explain much of the coast likely didn't move as far.

Thank You! I actually looked up the grand canyon stats and the sea bed rupture is actually 4-5 times wider than the grand canyon, and not quite as long but close!

Are you a scientist? What are your credentials?
It sickens me to see people come up with their "predictions" whenever a disaster like this happens. Are you giddily anticipating such a disaster?
The terms mud volcano or mud dome are used to refer to formations created by geo-excreted liquids and gases, although there are several different processes which may cause such activity. Hot water mixes with mud and surface deposits. Mud volcanoes are associated with subduction zones and about 700 have been identified. Temperatures are much cooler in these processes than found at igneous volcanoes. The largest mud volcano structures are 10 kilometres (6.2 mi) in diameter and reach 700 metres (2,300 ft) in height.
About 86% of the gas released from these structures is methane, with much less carbon dioxide and nitrogen emitted. Ejected materials are often a slurry of fine solids suspended in liquids which may include water, which is frequently acidic or salty, and hydrocarbon fluids.
An unnamed mud volcano 30 metres (98 ft) high and with a top about 100 metres (328 ft) wide, 24 kilometres (15 mi) off Redondo Beach, California, and 800 metres (2,620 ft) under the surface of the Pacific Ocean.
