Abstract Statistical earthquake forecasting models, such as the Epidemic‐type Aftershock Sequence (ETAS), embed decades of empirical knowledge and assumptions about earthquake triggering, clustering, and catalog completeness. In contrast, neural spatio‐temporal point process (STPP) models often treat seismicity as generic spatiotemporal data without ...

The control and management of mining-induced seismic hazards have attracted ever-rising attention, especially in underground longwall coal mines, where continuous mining activities dynamically alter the stress states and induce seismic events.

Abstract Temporal changes in seismicity rates can be conceptually understood as a response and consequence of stress changes. Dieterich (1994, https://doi.org/10.1029/93JB02581) formalized this relationship using empirically derived rate‐and‐state friction laws, and Heimisson and Segall (2018, https://doi.org/10.1029/2018JB015656) later generalized the

Highlights from the first ten years of the New Zealand earthquake forecast testing center [PDF]
We present highlights from the first decade of operation of the New Zealand Earthquake Forecast Testing Center of the Collaboratory for the Study of Earthquake Predictability (CSEP). Most results are based on reprocessing using the best available catalog,

Prototyping the Seismogenic Fault Injection Test (SFIT)
Abstract The treatment of induced seismicity risk would benefit from a small, standardized injection test that probes the seismic response to fluid injection—to optimally improve earthquake forecasts before a larger injection commences. To accomplish this goal, we propose a “model differencing” framework: this framework optimizes injection protocols by

The Q$$ Q $$‐Score: A Magnitude‐Weighted Goodness‐of‐Fit Score for Earthquake Forecasting
ABSTRACT Accurate forecasting of large earthquakes is of great importance, yet most current earthquake forecast evaluation metrics, such as the log‐likelihood score, do not give additional weight to large‐magnitude events. To this end, magnitude‐weighted goodness‐of‐fit scores for earthquake forecasting have recently been introduced, such as potency ...

Reduced seismic activity after mega earthquakes
Mainshocks are often followed by increased earthquake activity (aftershocks). According to the Omori-Utsu law, the rate of aftershocks decays as a power law over time.

Brittle Creep as a Mechanism for Postseismic Relaxation in Upper Crustal Dolomite Marble
Abstract In many locations, earthquakes in the upper crust occur in carbonate rocks, whose deformation affects aftershock sequences and postseismic relaxation. We investigate the stress relaxation process and strain evolution in Jinping dolomite marble (porosity <0.2%) subjected to multi‐stage stress ramp‐relaxation cycles under confining pressures of ...

Hidden jerk in universal creep and aftershocks [PDF]
Most materials exhibit creep memory under the action of a constant load. The memory behavior is governed by Andrade's creep law, which also has an inherent connection with the Omori-Utsu law of earthquake aftershocks.
