Predictability in the ETAS Model of Interacting Triggered Seismicity

, 2003
As part of an effort to develop a systematic methodology for earthquake forecasting, we use a simple model of seismicity based on interacting events which may trigger a cascade of earthquakes, known as the Epidemic-Type Aftershock Sequence model (ETAS ...

REVIEW One-Dimensional Dynamical Modeling of Earthquakes: A Review

Terrestrial, Atmospheric and Oceanic Sciences, 2008
Studies of the power-law relations of seismicity and earthquake source parameters based on the one-dimensional (1-D) Burridge-Knopoff¡¦s (BK) dynamical lattice model, especially those studies conducted by Taiwan¡¦s scientists, are reviewed in this ...

Interevent time distribution in seismicity: a theoretical approach

, 2004
This paper presents an analysis of the distribution of the time $\tau$ between two consecutive events in a stationary point process. The study is motivated by the discovery of a unified scaling law for $\tau$ for the case of seismic events.

Non-Markovian nature of cryptocurrencies

Frontiers in Physics
Whether financial assets movements exhibit correlation and memory has been an intriguing question for physicists. This study aims to investigate whether financial shocks exhibit non-Markovian behavior. In particular, it explores the presence of long-term

Correlated earthquakes in a self-organized model [PDF]

Nonlinear Processes in Geophysics, 2009
Motivated by the fact that empirical time series of earthquakes exhibit long-range correlations in space and time and the Gutenberg-Richter distribution of magnitudes, we propose a simple fault model that can account for these types of scale-invariance ...

Importance of small earthquakes for stress transfers and earthquake triggering

, 2004
We estimate the relative importance of small and large earthquakes for static stress changes and for earthquake triggering, assuming that earthquakes are triggered by static stress changes and that earthquakes are located on a fractal network of ...

Apparent Clustering and Apparent Background Earthquakes Biased by Undetected Seismicity

, 2005
In models of triggered seismicity and in their inversion with empirical data, the detection threshold m_d is commonly equated to the magnitude m_0 of the smallest triggering earthquake. This unjustified assumption neglects the possibility of shocks below

Complex networks of earthquakes and aftershocks [PDF]

Nonlinear Processes in Geophysics, 2005
We invoke a metric to quantify the correlation between any two earthquakes. This provides a simple and straightforward alternative to using space-time windows to detect aftershock sequences and obviates the need to distinguish main shocks from ...

Exploring the Dynamic Behavior of Crude Oil Prices in Times of Crisis: Quantifying the Aftershock Sequence of the COVID-19 Pandemic

Mathematics
Crude oil prices crashed and dropped into negative territory at the onset of the COVID-19 pandemic. This extreme event triggered a series of great-magnitude aftershocks.
