We present 2D dynamic rupture models of the 2011 Tohoku-Oki earthquake based on linear slip-weakening friction. We use different types of available observations to constrain our model parameters. The distribution of stress drop is determined by the final slip distribution from slip inversions. As three groups of along-dip slip distribution are suggested by different slip inversions, we present ...

This paper is concerned with some aspects of nonuniform stressing above a deep creeping portion of a fault zone prior to a large crust-breaking earthquake. The model that we use involves a slipping crack, representing the deeper, more stably sliding portions of the fault zone, which penetrates upward from depth and is blocked in the lower region of the seismogenic zone. When conditions are unif...

This paper investigates the quasi-static plane deformation of an isotropic thermoelastic half-space due to buried seismic sources and heat source. Governing equations of thermo-elasticity are solved to obtain solutions for seismic sources in a thermoelastic half-space. The general solutions are acquired with the aid of Laplace and Fourier transforms and with the use of boundary conditions. The ...

11 Earthquakes can rupture geometrically complex fault systems by breaching fault step-overs. 12 Quantifying the likelihood of rupture jump across step-overs is important to evaluate earth13 quake hazard and to understand the interactions between dynamic rupture and fault growth 14 processes. Here we investigate the role of seismogenic depth and background stress on phys15 ical limits of earthq...

The paper presents the results of an analysis faults different ranks near Okhotnichya Cave in Pribaikalye, aimed at identifying their role formation and evolution cave its adjacent areas. This was done using rank-wise structural-paragenetic faults, which forms basis a specialized mapping tool for fault zones. Factual evidence obtained through several methods. speleoinitiating fracture network s...

Abstract Strike-slip faults are classically associated with pull-apart basins where continental crust is thinned between two laterally offset fault segments. We propose a subsidence mechanism to explain the formation of new type basin no substantial segment or syn-strike-slip thinning observed. Such “flexural strike-slip basins” form due sediment load creating accommodation space by bending lit...

We determined the centroid moment tensor (CMT) solutions of earthquakes that occurred along the North Anatolian fault (NAF) beneath the Sea of Marmara and the Aegean Sea, using data obtained from Turkey’s broadband seismograph network. The CMT solution of the 2014 Aegean Sea earthquake (Mw 6.9) represents a strike-slip fault, consistent with the geometry of the NAF, and the source-time function...

[1] We estimate the slip distribution from the MW 8.1 Solomon Islands earthquake in 2007, from two post-seismic surveys measuring uplifted coral and submerged coastal features. The occurrence of islands extremely proximal to the trench and nucleation of rupture allowed for the collection of unprecedented coseismic deformation dataset along a large megathrust earthquake. Using data from the two ...
