Magnitude-Dependent Omori Law: Empirical Study and Theory
, 2004 We propose a new physically-based ``multifractal stress activation'' model of earthquake interaction and triggering based on two simple ingredients: (i) a seismic rupture results from activated processes giving an exponential dependence on the local ...

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 ...

地球与行星物理论评Dynamic triggering refers to the phenomenon of teleseismic waves propagating to some areas in a near-critical stress state, thus triggering earthquakes. Shallow earthquakes are the type of earthquakes that are most commonly triggered.

Terrestrial, Atmospheric and Oceanic Sciences, 2022 Key points 1. We used unsupervised machine-learning algorithms DBSCAN and PCA to study the 2018–2022 Hualien earthquake sequence. 2. A deep westward-dipping and a shallow rotation structure system are revealed from earthquake clusters close to the ...

A Hydrofracturing-Triggered Earthquake Occurred Three Years after the Stimulation
Energies, 2022 Hydrofracturing, used for shale gas exploitation, may induce felt, even damaging earthquakes. On 15 June 2019, an Mw2.8 earthquake occurred, spatially correlated with the location of earlier exploratory hydrofracturing operations for shale gas in Wysin ...

On near‐source earthquake triggering [PDF]
Journal of Geophysical Research: Solid Earth, 2009 When one earthquake triggers others nearby, what connects them? Two processes are observed: static stress change from fault offset and dynamic stress changes from passing seismic waves. In the near‐source region (r ≤ 50 km for M ∼ 5 sources) both processes may be operating, and since both mechanisms are expected to raise earthquake rates, it is ...

Earthquake‐induced landslide scenarios for seismic microzonation. Application to the Accumoli area (Rieti, Italy) [PDF]
, 2019 Scenarios of earthquake-induced landslides are necessary for seismic microzonation (SM) studies since they must be integrated with the mapping of instability areas.

A 3D model for earthquake-induced liquefaction triggering and post-liquefaction response
Soil Dynamics and Earthquake Engineering, 2018 A constitutive soil model that was originally developed to model liquefaction and cyclic mobility has been updated to comply with the established guidelines on the dependence of liquefaction triggering to the number of loading cycles, effective ...
