Journal of Geophysical Research: Solid Earth, 2023 Following laboratory experiments and friction theory, slow slip events and seismicity rate accelerations observed before mainshocks are sometimes interpreted as evidence of a nucleation phase. However, such precursory observations still remain scarce and

Foreshocks of the 2010 Mw 6.7 Yushu, China Earthquake Occurred Near an Extensional Step‐Over
Journal of Geophysical Research: Solid Earth, 2023 We conduct a detailed study of the foreshock sequence preceding the 2010 Mw 6.7 Yushu, Qinghai earthquake in the Tibetan plateau by examining continuous waveforms recorded at a seismic station near the mainshock rupture zone.

Characteristics of the foreshock occurrence for Mj3.0 to 7.2 shallow onshore earthquakes in Japan
Earth, Planets and Space, 2022 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

On the relevance of the foreshocks in forecasting seismic mainshocks
Annals of Geophysics, 2023 We analyze the usefulness of the foreshocks in forecasting seismic mainshocks. The analysis is based on possible correlations which may exist between foreshocks and mainshocks.

Research on Characteristics of Foreshocks of the Dengta M5.1 Earthquake Sequence in Liaoning [PDF]
E3S Web of Conferences, 2021 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 ...

Cluster-based foreshock discrimination model with flexible time horizon and mainshock magnitudes
Progress in Earth and Planetary Science, 2023 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
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.

New Physical Implications From Revisiting Foreshock Activity in Southern California
Geophysical Research Letters, 2023 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 ...
