The Carboneras fault is one of three principal Cenozoic strike-slip faults in the Betic Cordillera of southeastern Spain. In this study, we characterize the paleoseismic history of the Carboneras fault by examining the evidence for lateral offset of 85-180 ka ‘Iyrrhenian marine terraces, by dating the left-lateral stream-channel offsets in La Serrata, and by postulating a late Holocene coastal ...

[1] A sequence of large strike-slip earthquakes occurred west of Sunda Trench beneath the Wharton Basin. First reports indicate that the main shock was extremely complex, involving three to four subevents (Mw> 8) with a maze of aftershocks. We investigate slip models of the two largest earthquakes by joint inversion of regional and teleseismic waveform data. Using the Mw7.2 foreshock, we develo...

the zagros fold-and-thrust belt is tectonically active and often has active faults with insensible and slow motions. determining the rate of movement and displacement in these faults requires very precise measurements. one of the measurement methods of fault movements is using geodetic and micro-geodetic studies. this research is focused on one of the active faults in the north of shiraz city, ...

U the physics of complex phenomena such as earthquakes is a formidable challenge. Because we are constrained by our inability to do experiments on earthquake faults, we turn to computers as our earthquake laboratories. Computer simulations of earthquakes help us to test theoretical models and allow us to generate catalogs of synthetic earthquake events. In this column, we discuss several models...

Iran is located in a seismically active region and exposed to seismic activity from many seismic sources and active faults. Probabilistic seismic hazard assessment is the basis for many pre and postearthquake risk management issues. Definition and parameterization of active faults and seismic sources are among the most important aspect for reliable PSHA studies. In this paper an effort in desig...

Most of the earthquake faults in North-East India, China, mid Atlantic-ridge, the Pacific seismic belt and Japan are found to be predominantly dip-slip in nature. In the present paper a dip-slip fault is taken situated in an elastic layer over a viscoelastic half space representing the lithosphere-asthenosphere system. A movement of the dip-slip nature across the fault occurs when the accumulat...

Article history: Received 24 February 2016 Received in revised form 11 July 2016 Accepted 12 July 2016 Available online xxxx OnApril 25th 2015, theMw7.8 Gorkha (Nepal) earthquake ruptured a portion of theMain Himalayan Thrust underlying Kathmandu and surrounding regions. We develop kinematic slip models of the Gorkha earthquake using both a regularized multi-time-window (MTW) approach and an un...

One of the more enigmatic features of the Earth’s style of mantle convection is plate tectonics itself, in particular the existence of strike-slip, or toroidal, motion. Toroidal motion is uncharacteristic of basic thermal convection, but necessarily forms through the interaction of convective flow and nonlinear rheological mechanisms. Recent studies have implied that the empirically determined ...
