Low friction along the high slip patch 2011 Mw 9.0 Tohoku-Oki earthquake required the wedge structure extensional splay faults
2014/4/15
We analyze the mechanical properties needed to account for the large shallow slip during the 2011 Tohoku-Oki earthquake and the activation of landward normal faulting within the forearc. We show that ...
