Fig. 4: Slip-line field in the Indian-Eurasian collision zone built from plastic strain rate in the lower crust and upper mantle.
From: Three-dimensional kinematics of the India–Eurasia collision
a Layout of one set of slip lines built from the maximum shear of plastic strain rate, approaching the orientation of the ATF, HYF, KLF, XXF, and CMF left-lateral faults. b Orthogonal set of slip lines that matches the orientation of the KKF, SGF, TTF, and BOK right-lateral faults. The JLF and RRF are misoriented, compatible with their recent seismic quiescence. c Streamlines of horizontal compression, highlighting contractions at the margins of the collision zone, implying ongoing shortening. d Streamlines of horizontal extension, demonstrating large-scale extension within Central Tibet, the Yunnan province, and the Shan Plateau, compatible with the population of normal earthquakes. The beach balls indicate the focal mechanism of earthquakes of Mw≥6 since 1970135, filtered by strike-slip (red), normal (blue), and thrust (black) mechanisms.
