How Likely Does an Aftershock Sequence Conform to a Single Omori Law Behavior
Seismological Research Letters, 2018The most popular aftershock forecasting model is based on the modified Omori law (MOL), which describes the expected decay of the aftershock given the mainshock's magnitude. Although such a model is still widely used for operational purposes, it is not unusual that one or more aftershocks break the MOL behavior.

Omori Law After Exogenous Shocks on Supplier-Customer Network
, 2013We study the relaxation process of a supplier-customer network after mass destruction due to two giant earthquakes, Kobe 1995 and East Japan 2011, by investigating the number of chained failures. Firstly, a mass destruction and intervention of business activities in the damaged areas can be considered as a main shock. The exogenous shock was propagated

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.

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.

Financial crisis, Omori's law, and negative entropy flow
International Review of Financial Analysis, 2013Abstract The 2008 global financial crisis has revived great interest in early warning system (EWS) models for reducing the risks of future crises. Existing EWS models employ aggregated variables that cannot examine the nonlinear dynamics of participating players on scales smaller than a country in unstable, non-equilibrium economies.

Breaking Omori's Law of Public Awareness
Seismological Research Letters, 2005As seismologists dedicated to studying one of the Earth's most dangerous natural phenomena, we are inured to the reality that public interest in our field surges after a significant earthquake and decays rapidly afterward to a rather low background level. This would be little more than a curiosity were it not for the fact that understanding earthquakes
