Abstract We present here an analysis of the destructive Mw 6.2 earthquake sequence that took place on 14 January 2021 in Mamuju–Majene, West Sulawesi, Indonesia. Our relocated foreshocks, mainshock, and aftershocks their focal mechanisms show they occurred two different fault planes, which foreshock perturbed stress state a nearby segment, causing plane to subsequently rupture. The mainshock ha...

Abstract After a large earthquake, many small earthquakes, called aftershocks, ensue. Additional earthquakes typically do not occur, despite the fact that static stress near edges of fault is expected to trigger further at these locations. Here we analyse ~10,000 highly accurate focal mechanism solutions aftershocks 2016 Mw 6.2 Central Tottori earthquake in Japan. We determine location horizont...

We estimate the loading rate in southern California and the change in stress induced by a transient slip event across the San Andreas fault (SAF) system in central California, using a model of static fatigue. We analyze temporal properties of aftershocks in order to determine the time delay before the onset of the power law aftershock decay rate. In creep-slip and stick-slip zones, we show that...

[1] We argue that key features of thrust earthquake triggering, inhibition, and clustering can be explained by Coulomb stress changes, which we illustrate by a suite of representative models and by detailed examples. Whereas slip on surface-cutting thrust faults drops the stress in most of the adjacent crust, slip on blind thrust faults increases the stress on some nearby zones, particularly ab...

The northward migration of the Mendocino Triple Junction is associated with complex faulting within the Gorda plate and in the convergent zone between the Gorda and North American plates. This region has experienced substantial recent large earthquake activity, and quantification of these faulting processes i essential for understanding the evolution of the triple junction. Using an empirical G...

one of the methods for the determination of focal mechanisms of earthquakes is the linear inversion of moment tensor in time domain. that method is used here for determining of the focal mechanisms the darbe astaneh silakhor earthquake of 31 march 2006 and two of its foreshocks and six aftershocks with local magnitude more than 4. the data of six broadband stations of the international institut...
