Research on Characteristics of Foreshocks of the Dengta M5.1 Earthquake Sequence in Liaoning [PDF]
With the observed earthquake sequence data and the waveform data in the hypocenter region of the M5.1 earthquake that hit Dengta County in Liaoning on 23rd January, 2013, this study calculated the amplitude spectrum correlation coefficient before and ...

Characteristics of the foreshock occurrence for Mj3.0 to 7.2 shallow onshore earthquakes in Japan
We use the Japan Meteorological Agency (JMA) earthquake catalogue from January, 2001 to February, 2021 to investigate the spatiotemporal foreshock occurrence for shallow (within 30 km depth) onshore earthquakes (Mj3.0 to 7.2). We find clear peaks for the

Cluster-based foreshock discrimination model with flexible time horizon and mainshock magnitudes
Foreshock detection before mainshock occurrence is an important challenge limiting the short-term forecasts of large earthquakes. Various models for predicting mainshocks based on discrimination of foreshocks activity have been proposed, but many of them

The Crete Isl. (Greece) Mw6.0 Earthquake of 27 September 2021: Expecting the Unexpected
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.

New Physical Implications From Revisiting Foreshock Activity in Southern California
Foreshock analysis promises new insights into the earthquake nucleation process and could potentially improve earthquake forecasting. Well‐performing clustering models like the Epidemic‐Type Aftershock Sequence (ETAS) model assume that foreshocks and ...

Properties of Foreshocks and Aftershocks of the Non-Conservative SOC Olami-Feder-Christensen Model: Triggered or Critical Earthquakes? [PDF]
Following Hergarten and Neugebauer [2002] who discovered aftershock and foreshock sequences in the Olami-Feder-Christensen (OFC) discrete block-spring earthquake model, we investigate to what degree the simple toppling mechanism of this model is ...

ARTEMIS Observations of Foreshock Transients in the Midtail Foreshock
AbstractForeshock transients such as hot flow anomalies (HFAs) are frequently observed in the dayside foreshock. They can disturb the local bow shock, magnetopause, and consequently the magnetosphere‐ionosphere system through dynamic pressure perturbations. Recent multipoint observations found that such perturbations can even propagate from the dayside

The Unlocking Process Leading to the 2016 Central Italy Seismic Sequence
Approximately 23,000 well‐located earthquakes from 2009 to 2016 are used as templates to recover seismic activity preceding the 2016 Central Italy seismic sequence.

Incorporating Foreshocks in an Epidemic-like Description of Seismic Occurrence in Italy
The Epidemic Type Aftershock Sequence (ETAS) model is a widely used tool for cluster analysis and forecasting, owing to its ability to accurately predict aftershock occurrences.
