Omori law for eruption foreshocks and aftershocks [PDF]

Journal of Geophysical Research: Solid Earth, 2012
Using the 1973–2009 worldwide catalogs forM≥ 4.8 seismicity andVEI≥ 0 volcano eruptions, we compare the properties of seismic damage patterns contemporary with eruption with the properties of foreshocks and aftershocks of classic tectonic earthquakes. Using superposed epoch analysis, we demonstrated that the seismicity rate after eruption decreases as ...

Mainshocks are aftershocks of conditional foreshocks: How do foreshock statistical properties emerge from aftershock laws [PDF]

, 2003
The inverse Omori law for foreshocks discovered in the 1970s states that the rate of earthquakes prior to a mainshock increases on average as a power law ~ 1/(t_c-t)^p' of the time to the mainshock occurring at t_c.

A generalized Omori's law for earthquake aftershock decay [PDF]

Geophysical Research Letters, 2004
Earthquake aftershock sequences have been found to approximately satisfy three empirical scaling relations: i) the Gutenberg‐Richter frequency‐magnitude scaling, ii) Båth's law for the difference in the magnitude of a mainshock and its largest aftershock, and iii) the modified Omori's law for the temporal decay of aftershock rates.

Bridging aero-fracture evolution with the characteristics of the acoustic emissions in a porous medium

Frontiers in Physics, 2015
The characterization and understanding of rock deformation processes due to fluid flow is a challenging problem with numerous applications. The signature of this problem can be found in Earth Science and Physics, notably with applications in natural ...

“Aftershock Faults” and What They Could Mean for Seismic Hazard Assessment [PDF]

The Seismic Record, 2023
We study stress‐loading mechanisms for the California faults used in rupture forecasts. Stress accumulation drives earthquakes, and that accumulation mechanism governs recurrence.

Sub-critical and Super-critical Regimes in Epidemic Models of Earthquake Aftershocks [PDF]

, 2002
We present an analytical solution and numerical tests of the epidemic-type aftershock (ETAS) model for aftershocks, which describes foreshocks, aftershocks and mainshocks on the same footing.

Transient postseismic slip and aftershock triggering: A case study of the 2008 MW7.9 Wenchuan Earthquake, China[Key points]

Earthquake Science, 2023
In this study, we investigate how a stress variation generated by a fault that experiences transient postseismic slip (TPS) affects the rate of aftershocks.

Creep rupture as a non-homogeneous Poissonian process [PDF]

, 2013
Creep rupture of heterogeneous materials occurring under constant sub-critical external loads is responsible for the collapse of engineering constructions and for natural catastrophes.

Power-law relaxation in a complex system: Omori law after a financial market crash [PDF]

Physical Review E, 2003
We study the relaxation dynamics of a financial market just after the occurrence of a crash by investigating the number of times the absolute value of an index return is exceeding a given threshold value. We show that the empirical observation of a power law evolution of the number of events exceeding the selected threshold (a behavior known as the ...
