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.

A neural encoder for earthquake rate forecasting [PDF]
Scientific Reports, 2023 Forecasting the timing of earthquakes is a long-standing challenge. Moreover, it is still debated how to formulate this problem in a useful manner, or to compare the predictive power of different models.

High probability of successive occurrence of Nankai megathrust earthquakes [PDF]
Scientific Reports, 2023 Great earthquakes along the Nankai megathrust in south-western Japan feature in the top priority list of Japan’s disaster management agenda. In May 2019, an alert system was incepted to issue public warnings when the probability of an earthquake ...

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.

Dependence of the Omori‐Utsu law parameters on main shock magnitude: Observations and modeling [PDF]
Journal of Geophysical Research, 2008 We examine the dependence on main shock magnitudemof thepandχparameters appearing in Omori‐Utsu formulaλ(t,m) =χ× (t+c)−prelating the rate of aftershocksλat timetafter a main shock. Observations point out to a significant increase ofpwithm, along with a scaling relationship of the formχ∼ 10αm.

Stress spatial distributions, the Gutenberg–Richter and Omori–Utsu laws
Journal of Statistical Mechanics: Theory and ExperimentAbstract We investigate several earthquake models in one and two dimensions of space and analyze in these models the stress spatial distribution. We show that the statistical properties of stress distribution are responsible for the distribution of earthquake magnitudes, as described by the Gutenberg–Richter (GR) law.
