Invited by State Key Laboratory of Geodesy and Earth`s Dynamics (SKLGED) professor James Mori from institute of disaster prevention, Kyoto University, Japan visited Geodesy and Geophysics, Chinese Academy of Sciences (IGG, CAS) on May, 6. He gave a report on Japan Trench Fast Drilling Project (JFAST):  Investigation of the Large Slip during the 2011 Tohoku-oki Earthquake. The meeting was held by researcher Zheng Yong, present at the meeting were about 20 researchers and students.

The report introduced the Japan Trench Fast Drilling Fast Project launched after march 11, focusing on the background, scientific objects and achievements of the project. Researchers found that the thickness between two plates is smaller than 5m, the rubbing factor is 0.1 by measuring the temperature, stress state and analyzing the samples of the fault zone. Thus, professor Mori deemed that the 2011 tsunami caused by earthquake in Japan was due to the low friction and thinness of the fault zone.
