Variations in diurnal tidal stress due to Europa’s eccentric orbit have been considered as the driver of strike-slip motion along pre-existing faults, but obliquity and physical libration have not been taken into account. The first objective of this work is to examine the effects of obliquity on the predicted global pattern of fault slip directions based on a tidal-tectonic formation model. Our...

An MJMA6.5 earthquake (foreshock) and MJMA7.3 earthquake (mainshock) struck Kumamoto Prefecture on April 14, 2016, and April 16, 2016. To evaluate the effect of crustal deformation due to the earthquake on the Aso magma system, we detected crustal deformation using InSAR and GNSS. From InSAR analysis, we detected large crustal deformations along the Hinagu Fault, the Futagawa Fault, and the nor...

To validate the abundance of scenarios of large earthquakes in the Nankai Trough, we examined the effects of both lateral and vertical expansions of the source areas on maximum tsunami heights along the Pacific coast and Seto Inland Sea. The recently proposed Nankai Trough earthquake scenario (Mw = 9) has a maximum slip of 20 m near the trough axis. However, the predicted tsunami heights exceed...

The evolution of rift basins is often influenced by the reactivation pre-existing structures, a response that partly controlled angular relationship between fault strike and subsequent extension/compression axes. In Celtic Sea basins, offshore Ireland, Caledonian Variscan structures form heterogeneous basement for rifting in Triassic–Jurassic Cretaceous later Pyrenean inversion Paleogene. Using...

The Brawley fault zone (BFZ) and the Brawley Seismic Zone constitute the principal transfer zone accommodating strain between the San Andreas and Imperial faults in southernmost California. The BFZ ruptured along with the Imperial fault in the 1940 Mw 6.9 and the 1979 Mw 6.4 earthquakes, although in each case only minor slip apparently occurred on the BFZ; several other episodes of slip and cre...

In recent years, the Ordovician fault-controlled fracture-cavity reservoirs developed in basement strike-slip fault zone Shunbei area of Tarim Basin has achieved major breakthroughs. However, during drilling process area, problem mud leakage frequently interbedded Silurian sandstone and mudstone strata overlying target layer is very significant, it seriously affected normal wellbore stability. ...

[1] Radar interferometry (InSAR), field measurements and creepmeters reveal surface slip on multiple faults in the Imperial Valley triggered by the main shock of the 4 April 2010 El Mayor‐Cucapah Mw 7.2 earthquake. Co‐seismic offsets occurred on the San Andreas, Superstition Hills, Imperial, Elmore Ranch, Wienert, Coyote Creek, Elsinore, Yuha, and several minor faults near the town of Ocotillo ...

Pull-apart basins are faulting and folding zones with high intensity of fractures that strongly affect the production in unconventional shale gas. While most observations pull-apart were from surface mapping or laboratory experiments, we investigated a nascent basin subsurface. We characterized along strike-slip fault within Woodford Shale by using seismic attributes analyses, including coheren...
