Large earthquakes are usually modeled with simple planar fault surfaces or a combination of several segments. However, in general, occur on faults that non-planar and exhibit significant geometrical variations both the along-strike down-dip directions at all spatial scales. Mapping surface ruptures high-resolution geodetic observations increasingly revealing complex geometries near accurate loc...

Why many major strike-slip faults known to have had large earthquakes are silent in the interseismic period is a long-standing enigma. One would expect small earthquakes to occur at least at the bottom of the seismogenic zone, where deeper aseismic deformation concentrates loading. We suggest that the absence of such concentrated microseismicity indicates deep rupture past the seismogenic zone ...

This work focuses on a ca. 55 km-long extensional fault zone buried underneath the foredeep deposits of southern Apennines, Italy, with goal deciphering Cenozoic growth mechanisms in Outer Apulian Platform. By considering public 2D seismic reflection profiles, well logs, and isochron maps data, study normal is interpreted as made up four individual segments crosscutting Top Cretaceous, Eocene, ...

The service experts assess the condition of the vehicles based on the produced sound. To benefit both, the riders and the experts, the fault diagnosis process needs to be automated. The paper presents a methodology for fault detection of motorcycles, which uses the slopes of the eight pseudospectral segments as features. The computed features are classified into healthy and faulty using artific...

The article presents a method of selecting an arch yielding support for preparatory workings driven in hard coal seam. Particular attention was paid to discontinuous deformation the form fault, which significantly contributes change excavation protection schemes. On basis geometry machines and devices designed excavation, selected, then checked ventilation criterion. In next stage, analytical c...

Abstract We reveal the existence of a previously unknown fault that generated Mw 7.3 Flores Sea earthquake, which occurred on 14 December 2021, approximately 100 km to north Island, in one most complex tectonic settings Indonesia. use double-difference method relocate hypocenters mainshock and aftershocks, determine focal mechanisms using waveform inversion, then analyze stress changes estimate...

Abstract Normal faults are commonly segmented along strike, with segments that localize strain and influence propagation of slip during earthquakes. Although the geometry can be constrained by fault mapping, it is challenging to determine seismically relevant a zone. Because histories, geometries, strengths linkages between normal fundamentally control rupture earthquakes, differences in segmen...

Numerical models of earthquake rupture are used to investigate characteristic length scales and size distributions of repeated earthquakes on vertical, planar fault segments. The models are based on exact solutions of static three-dimensional (3-D) elasticity. Dynamical rupture is approximated by allowing the static stress field to expand from slip motions at a single velocity. To show how the ...
