The 2013 Mw7.7 Balochistan earthquake: Seismic potential of an accretionary wedge
Great earthquakes rarely occur within active accretionary prisms, despite the intense long-term deformation associated with the formation of these geologic structures. This paucity of earthquakes is often attributed to partitioning of deformation across multiple structures as well as aseismic deformation within and at the base of the prism (Davis et al., 1983). We use teleseismic data and satel...
متن کاملThe 2013, Mw 7.7 Balochistan earthquake, energetic strike-slip reactivation of a thrust fault
1 a r t i c l e i n f o a b s t r a c t Keywords: Balochistan earthquake Chaman fault Makran megathrust earthquake source model image geodesy We analyse the Mw 7.7 Balochistan earthquake of 09/24/2013 based on ground surface deformation measured from sub-pixel correlation of Landsat-8 images, combined with back-projection and finite source modeling of teleseismic waveforms. The earthquake nucle...
متن کاملAccretionary prisms in subduction earthquake cycles: The theory of dynamic Coulomb wedge
[1] We expand the theory of critically tapered Coulomb wedge for accretionary prisms by considering stress changes in subduction earthquake cycles. Building on the Coulomb plasticity of the classical theory, we assume an elastic–perfectly Coulomb plastic rheology and derive exact stress solutions for stable and critical wedges. The new theory postulates that the actively deforming, most seaward...
متن کاملSupershear rupture in the 24 May 2013 Mw 6.7 Okhotsk deep earthquake: Additional evidence from regional seismic stations
Zhan et al. (2014a) reported supershear rupture during the Mw 6.7 aftershock of the 2013 Mw 8.3 Sea of Okhotsk deep earthquake, relying heavily on the regional station PET, which played a critical role in constraining the vertical rupture dimension and rupture speed. Here we include fivemore regional stations and find that the durations of the source time functions derived from these stations a...
متن کاملSlip model of the 2008 Mw 7.9 Wenchuan (China) earthquake derived from co-seismic GPS data
Near-field co-seismic GPS data were used to derive the slip distribution of the 12 May 2008 Wenchuan earthquake. Based on field measurements and geological observations, the earthquake is represented by ruptures on the Beichuan fault and a neighboring fault from Pengxian to Guanxian, both dipping with a decreasing angle with depth. Using a layered elastic crust model, we obtained a slip model t...
