Japan Trench Fast Drilling Project (JFAST) 

-Importance for Understanding the Devastating Tsunami from the 2011 Tohoku Earthquake-

The Deep-Sea Scientific Drilling Vessel Chikyu, operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), will embark on Integrated Ocean Drilling Program (IODP) Expedition 343 Japan Trench Fast Drilling Project (JFAST), from 1 April to 24 May 2012.

The main goal of the JFAST project is to understand the very large fault slip that occurred on the shallow portion of the subuction zone during the 2011 Tohoku earthquake. This large slip of 30 to 50 meters was the main source of the devastating tsunami that caused so much damage and loss of lives along the northeast coast of Honshu, Japan. Understanding the Tohoku earthquake and tsunami has obvious consequences for evaluating the hazards at other subduction zones around the world.

Dr. James J. Mori and Dr. Frederick M. Chester, Co-Chiefs of this expedition, sent special comments on this expedition:

"The 2011 Tohoku earthquake shocked the people of Japan, as well as earthquake experts, because of the huge tsunami that caused so much damage and took so many lives. The seismological, geological, and ocean science communities have a clear obligation to learn and explain as much as possible about this event. The earthquake occurred in the sub-seafloor, which is the realm of IODP research, so its scientists should be leading these important investigations” (Dr. Mori)

“I acknowledge the importance and engineering difficulty of IODP Expedition 343. Through cooperation between ship-board scientists, on-shore advisors, and the ship operators and drillers, I am confident that we can achieve the science goals of the expedition. I believe that the knowledge gained from this expedition will someday help mitigate hazards of future earthquakes and tsunamis." (Dr. Chester)
