Tectonic Implications of Subcrustal, Normal Faulting Earthquakes in the Western Shikoku Region, Japan
Tectonic implications of subcrustal, normal faulting earthquakes in the western Shikoku region have been investigated in sorme detail, mainly based on the faulting mechanism of the Bungo channel earthquake of August 6, 1968 (M=6.6, h=45km) and its aftershocks. A synthetic study of the focal mechanism solution, spatial distribution of aftershocks, seismic waves observed in the near and far field...
متن کاملConditions for Thrust Faulting in a Glacier
Dipping, arcuate bands of debris-rich ice outcropping near the margins of glaciers are often interpreted as thrust faults, assumed to originate in zones of longitudinal compression. Identification of thrusts is typically based either on the geometry and sedimentology of the debris bands or on the crystal fabric of surrounding ice, but the physical processes necessary to generate thrusts are rar...
متن کاملMiddle Miocene reorganization of deformation along the northeastern Tibetan
Temporal variations in the orientation of Cenozoic range growth in northeastern Tibet defi ne two modes by which India-Asia convergence was accommodated. Thermochronological age-elevation transects from the hanging walls of two major thrust-fault systems reveal diachronous Miocene exhumation of the Laji-Jishi Shan in northeastern Tibet. Whereas accelerated growth of the WNW-trending eastern Laj...
متن کاملMiddle Miocene hominoid origins.
Ward et al. (1) ably show that samples of thickly enameled Middle Miocene hominoids that they attribute to a new genus, Equatorius, are distinct from Kenyapithecus. They fail to show, however, how Equatorius differs from Griphopithecus. In so doing, they may have missed the hominoid connection between Eurasia and Africa by 2 to 3 million years. The authors note the presence of a welldeveloped b...
متن کاملAlong-strike changes in Himalayan thrust geometry: Topographic and tectonic discontinuities in western Nepal
Geodetic and seismologic studies support a tectonic model for the central Himalaya wherein ~2 cm/yr of Indo-Asian convergence is accommodated along the primary décollement under the range, the Main Himalayan thrust. A steeper midcrustal ramp in the Main Himalayan thrust is commonly invoked as driving rapid rock uplift along a range-parallel band in the Greater Himalaya. This tectonic model, dev...
