Two-dimensional lattice particle models have been used to simulate dynamic thrust faulting and its effects on near-fault ground motions. The lattice particle modeling approach has been demonstrated as an efficient way to model the dynamic rupture phenomena observed from a foam rubber experiment on dipping faults. We constructed a 42 dipping fault model to simulate near-fault ground motions unde...

The occurrence regularity of the coal mine earthquake under influence hard roof, fault, and mining was studied by theoretical analysis, field investigation, monitoring data analysis for phenomenon rock burst induced earthquakes. dissipation characteristics energy propagation considering a hypocenter scale were described, response analyzed. two principles fractured type earthquakes three princip...

6 [1] We examine the work energy budget of actively deforming fault systems in order to 7 develop a means of examining the systemic behavior of complex fault networks. Work 8 done in the deformation of a faulted area consists of five components: (1) work done 9 against gravity in uplift of topography (Wgrav); (2) internal energy of the strained host rock 10 (Wint); (3) work done resisting frict...

S U M M A R Y We perform a systematic analysis of crustal anisotropy along and around the Karadere–Düzce branch of the North Anatolian fault (NAF), which ruptured during the 1999 Mw 7.4 İzmit and Mw 7.1 Düzce earthquakes. A method consisting of an iterative grid search for the best shear wave splitting parameters in sliding time windows is applied to ∼22 000 measurements recorded in the 6-month...

This work describes the collection and properties of publicly available rock drill fault classification data set rockdrill11, used for 2022 PHM Conference Data Challenge. The is collected from a carefully instrumented hydraulic drill, operating in normal operation test cell while inducing number faults. Hydraulic pressure measured at 50kHz three different locations, resulting detailed signature...

The coal exploitation in the Upper Silesia region (along Vistula River) triggers strata seismic activity, characterized by very high energy, which can create mining damage of surface objects, without any noticeable damages underground structures. It is assumed that appearance energy events result faults’ activation vicinity excavation. This paper presents analysis a case study one mine, where d...

We present a two-dimensional analytical solution for the static stress field around rough interlocked interface under background stresses and its applications to faulting. The is derived using perturbation theory defined topography stresses. failure-ratio, which scales likelihood failure of bulk material interface, calculated adopting Coulomb criterion. compare model predictions with results ex...
