Figure 4From: Frictional properties of incoming pelagic sediments at the Japan Trench: implications for large slip at a shallow plate boundary during the 2011 Tohoku earthquakeSEM photomicrographs of Cores 38 (a) and 40 (b). The two core samples were deformed at a normal stress of 1.0 MPa and slip velocity of 1.3 m/s (run numbers are HVR 3278 and 3265, respectively).Back to article page
