Three-dimensional mechanical models are used to evaluate the performance of different fault growth criteria in predicting successive growth of three échelon thrust faults similar to the segments of the Puente Hills thrust system of the Los Angeles basin, California. Four sequential Boundary Element Method models explore the growth of successive échelon faults within the system by simulating sna...

The Iberian Peninsula and the Maghreb experience moderate earthquake activity and oblique, ∼ NW–SE convergence between Africa and Eurasia at a rate of ∼ 5 mm/yr. Coeval extension in the Alboran Basin and a N35°E trending band of active, left-lateral shear deformation in the Alboran–Betic region are not straightforward to understand in the context of regional shortening, and evidence complexity ...

The seismicity of southern Spain is characterized by low-to-moderate earthquake activity (magnitudes <5.5) related to the convergence of the African and Eurasian plates. The detailed structure of this complex plate boundary is not well understood and the study of faulting parameters and depths of the small-to-moderate-size events can contribute much to our understanding of the regional stresses...

The eastern boundary of the Southern Cascades (Hat Creek Graben region), California, USA, is an extensively faulted volcanic corridor between the Cascade Range and Modoc Plateau. The morphology of the region is a result of plate motions associated with different tectonic provinces, faulting, and recurring volcanic activity, making it an ideal place to study the interrelationship between tectoni...

The study of faulting and earthquake processes requires direct and near-fi eld observations at the focal depth. Deep mines provide a unique opportunity to make such observations. The linked DAFSAM (Drilling Active Faults Laboratory in South African Mines)-NELSAM (Natural Earthquake Laboratory in South African Mines) projects focus on building an earthquake laboratory in deep gold mines in South...

the source parameters and focal depth of the destructive mw 6.5, 31 march. 2006 iran- silakhor earthquake, the two largest foreshocks and a major aftershock are determined using broadband data from a seismic network in iran based on a time-domain linear moment tensor inversion. the earthquakes occurred in the zagros suture zone in western iran. waveform inversion of the selected events estimate...
