Dynamical scaling and generalized Omori law [PDF]
Geophysical Research Letters, 2007 The power law decay of the aftershocks rate is observed only after a characteristic time scale c. The dependence of c on the mainshock magnitude MM and on the lower cut‐off magnitude MI is well established. By considering ten sequences recorded in the California Catalog we show that the aftershock number distribution becomes independent of both MM and ...

Omori law for sliding of blocks on inclined rough surfaces [PDF]
Physica A: Statistical Mechanics and its Applications, 2001 Long sequences of slidings of solid blocks on an inclined rough surface subjected to small controlled perturbations are examined and scaling relations are found for the time distribution of slidings between pairs of large events as well as after and ...

Generalized Omori–Utsu law for aftershock sequences in southern California [PDF]
Geophysical Journal International, 2015 We investigate the validity of a proposed generalized Omori–Utsu law for the aftershock sequences for the Landers, Hector Mine, Northridge and Superstition Hills earthquakes, the four largest events in the southern California catalogue we analyse.

Multifractal Omori law for earthquake triggering: new tests on the California, Japan and worldwide catalogues [PDF]
Geophysical Journal International, 2009 SUMMARY The Multifractal Stress-Activated model is a statistical model of triggered seismicity based on mechanical and thermodynamic principles. It predicts that, above a triggering magnitude cut-off M 0, the exponent p of the Omori law for the time ...

Omori Law after Large-Scale Destruction of Production Network [PDF]
Progress of Theoretical Physics Supplement, 2012 After the two giant earthquakes, Kobe 1995 and East Japan 2011, a large-scale destruction took place on supplier-customer network. These primary and exogenous shocks were propagated on the production network, which caused a secondary effect resulting in chained bankruptcies.

Generalized Omori law for aftershocks and foreshocks from a simple dynamics
Geophysical Research Letters, 1993 A theory of the time dependence of earthquake foreshocks and aftershocks is presented. The theory involves the response to sudden forcing of a dynamics of self‐driven acceleration to failure. The empirically observed Omori law, which says that the rate of aftershocks as a function of time falls as a power law in time, is derived theoretically.

Market dynamics immediately before and after financial shocks: quantifying the Omori, productivity and Bath laws [PDF]
, 2010 We study the cascading dynamics immediately before and immediately after 219 market shocks. We define the time of a market shock T_{c} to be the time for which the market volatility V(T_{c}) has a peak that exceeds a predetermined threshold.

Deviation from the Omori law as the result of the trigger impact of round‐the‐world surface seismic waves on the source of strong earthquakes [PDF]
Acta Geologica Sinica - English Edition, 2019 In recent works we have discovered and described new previously unknown patterns in the dynamics of the aftershock flow (Gugliemi, Zotov, 2013; Gugliemi, Zotov, Zavyalov, 2014; Gugliemi, Zavyalov, Zotov, Lavrov, 2017).

Aftershocks and Fluctuating Diffusivity [PDF]
Entropy, 2023 The Omori-Utsu law shows the temporal power-law-like decrease of the frequency of earthquake aftershocks and, interestingly, is found in a variety of complex systems/phenomena exhibiting catastrophes.
