Relationship Between the 2019 Ridgecrest, California, M_W7.1 Earthquake and Its M_W6.4 Foreshock Sequence [PDF]

Entropy
The 2019 Ridgecrest MW7.1 earthquake has received significant attention due to its complex fault activity. It is also noticeable for its MW6.4 foreshock sequence.

The Crete Isl. (Greece) M_w6.0 Earthquake of 27 September 2021: Expecting the Unexpected

GeoHazards, 2022
The 27 September 2021 damaging mainshock (Mw6.0) is the first known strong earthquake that ruptured the Arkalochori area, Crete Isl., Greece, during the entire historical period, making it an unexpected event in the long-term sense.

On the Possibility of Reproducing Utsu’s Law for Earthquakes with a Spring-Block SOC Model

Entropy, 2023
The Olami, Feder and Christensen (OFC) spring-block model has proven to be a powerful tool for analyzing and comparing synthetic and real earthquakes. This work proposes the possible reproduction of Utsu’s law for earthquakes in the OFC model.

Spatiotemporal Clustering of Seismicity in the Kiskatinaw Seismic Monitoring and Mitigation Area

Frontiers in Earth Science, 2022
Induced seismicity has become a concern for industry and nearby residents. Fluid-induced earthquakes are a side effect of industrial operations such as hydraulic fracturing, where high-pressure fluids are pumped into the Earth’s crust to increase ...

Earthquake Productivity Law in a Wide Magnitude Range

Frontiers in Earth Science, 2022
Earthquakes are usually followed by aftershocks. The number of aftershocks—the so-called productivity—depends on the magnitude of the earthquake. In seismic modeling it is usually assumed that the number of aftershocks is approximately the same for ...

Power Law Distributions of Offspring and Generation Numbers in Branching Models of Earthquake Triggering [PDF]

, 2004
We consider a general stochastic branching process, which is relevant to earthquakes as well as to many other systems, and we study the distributions of the total number of offsprings (direct and indirect aftershocks in seismicity) and of the total ...

Engineering Applications Using Probabilistic Aftershock Hazard Analyses: Aftershock Hazard Map and Load Combination of Aftershocks and Tsunamis

Geosciences, 2017
After the Tohoku earthquake in 2011, we observed that aftershocks tended to occur in a wide region after such a large earthquake. These aftershocks resulted in secondary damage or delayed rescue and recovery activities.

Non‐Triggering and Then Triggering of a Repeating Aftershock Sequence in the Dead Sea by the 2023 Kahramanmaraş Earthquake Pair: Implications for the Physics of Remote Delayed Aftershocks

Geophysical Research Letters, 2023
Most aftershocks occur in areas experiencing large co‐seismic stress changes, yet some occur long after the mainshock in remote lightly stressed regions. The triggering mechanism of these remote delayed aftershocks is not well understood.

Perbandingan Energi Gempa Bumi Utama dan Susulan (Studi Kasus : Gempa Subduksi Pulau Sumatera dan Jawa)

Jurnal Fisika Flux, 2017
Indonesia is located on the third meeting of the active tectonic world plates which are Eurasian Indian - Australia and the Pacific Plate. This condition makes Indonesia as a tectonically active area with seismicity level or pattern of high seismicity ...

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.
