Probability Gain due to Foreshocks following Quiescence Tested by Synthetic Catalogs

, 1996
In order to investigate the factors that could contribute to the high values of the probability gain for foreshocks, we make use of synthetic catalogs generated by a computer program (Console et al., 1993b).

Role of a Hidden Fault in the Early Process of the 2024 Mw7.5 Noto Peninsula Earthquake

Geophysical Research Letters
The 2024 Mw 7.5 Noto Peninsula, Japan, earthquake was initiated within the source region of intense swarm activity. To reveal the mainshock early process, we relocated the earthquake hypocenters and found that many key phenomena, including the mainshock ...

Mesoscopic mechanism behind the inherent reliquefaction resistance subjected to repeated earthquakes using centrifuge modelling and advanced digital image processing

Soils and Foundations
Around the world severe damages were observed due to reliquefaction during repeated earthquakes, whereas precise understanding of its mesoscopic mechanism is not much discovered.

Omori law for foreshocks and aftershocks in a realistic earthquake model

, 2019
We study a physical model for earthquakes which extends the standard spring-block model. It is able to quantitatively describe the observations which detect differences between the statistics of foreshocks and aftershocks and the properties of main ...

Hydraulic Control of the Foreshocks and Mainshock of the 2017 Valparaíso, Chile, Earthquake

Geophysical Research Letters
Slow‐slip events (SSE) are a key mode of aseismic deformation and can enhance fault permeability through fracturing, enabling fluid migration from the overpressured oceanic crust to the plate interface.

Statistical Features of Foreshocks in Instrumental and ETAS Catalogs

, 2017
We study the spatial distribution of earthquakes in temporal intervals before and after the occurrence of large shocks (mainshocks) in the magnitude range m∈ [ 2 , 5 ] for four different regional catalogs.

Spatial organization of foreshocks as a tool to forecast large earthquakes

, 2012
An increase in the number of smaller magnitude events, retrospectively named foreshocks, is often observed before large earthquakes. We show that the linear density probability of earthquakes occurring before and after small or intermediate mainshocks ...

Wei-Jin Dynasty: Talking about seismic activity

地震科学进展
Talking about China’s seismicity research inevitably involves an outstanding female scientist, Mei Shirong. She does not have the title of academician, but is recognized and irreplaceable as an academic leader in the field of earthquake prediction in ...
