Recent Seismic Sequences and Activation of Normal Fault Systems in the Mugello Basin and Surrounding Areas (Northern Apennines, Italy)

open access: yesFrontiers in Earth Science, 2022
The Mugello Basin (North-Eastern Tuscany) is an intermontane basin of the Northern Apennines (Italy) with a well-documented record of seismicity; the two major historical earthquakes occurred in 1542 (Mw = 6.0) and in 1919 (Mw = 6.4).

Viscoelastic Slider Blocks as a Model for a Seismogenic Fault

open access: yesEntropy, 2023
In this work, a model is proposed to examine the role of viscoelasticity in the generation of simulated earthquake-like events. This model serves to investigate how nonlinear processes in the Earth’s crust affect the triggering and decay patterns of ...

Introduction to special section: Stress transfer, earthquake triggering, and time-dependent seismic hazard [PDF]

open access: yes, 2005
[1] In this introduction, we review much of the recent work related to stress transfer, earthquake triggering, and time-dependent seismic hazard in order to provide context for the special section on these subjects.

Advances in the spatiotemporal characteristics and mechanisms of earthquake static and dynamic triggering

open access: yes地球与行星物理论评
The static and dynamic stress changes induced by earthquakes can further trigger seismic events on surrounding or even remote faults. This phenomenon, known as static and dynamic triggering of earthquakes, has significant implications for earthquake ...

Pervasive Foreshock Activity Across Southern California

open access: yesGeophysical Research Letters, 2019
Foreshocks have been documented as preceding less than half of all mainshock earthquakes. These observations are difficult to reconcile with laboratory earthquake experiments and theoretical models of earthquake nucleation, which both suggest that ...

Tectonic tremors in the Northern Mexican subduction zone remotely triggered by the 2017 M w8.2 Tehuantepec earthquake

open access: yesEarth, Planets and Space, 2021
Surface waves from the 2017 M w8.2 Tehuantepec earthquake remotely triggered tectonic tremors in the Jalisco region, approximately 1000 km WNW in the northern Mexican subduction zone.

Crustal P-wave Velocity Structure and Seismogenic Mechanism Constraints in the Kamchatka 2025 MW8.8 Earthquake

open access: yesCT Lilun yu yingyong yanjiu
An intra-crustal MW8.8 strong earthquake occurred off the eastern coast of Kamchatka, triggering a tsunami and attracting global attention. Some researchers have analyzed the mechanical mechanism of this strong earthquake from the stress field.

Regional variations in the diffusion of triggered seismicity [PDF]

open access: yes, 2005
We determine the spatiotemporal characteristics of interearthquake triggering in the International Seismological Centre catalogue on regional and global scales. We pose a null hypothesis of spatially clustered, temporally random seismicity, and determine

Remotely triggered subsidence acceleration in Mexico City induced by the September 2017 Mw 7.1 Puebla and the Mw 8.2 Tehuantepec September 2017 earthquakes [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2020
Mexico City, a large megacity with over 21 million inhabitants, is exposed to several hazards, including land subsidence, earthquakes, and flooding.

Climate Change is Rewriting the Hydroclimatic Operating Envelope of Mines

open access: yesAdvanced Science, EarlyView.
Climate change is shown to shift the hydroclimatic operating envelope of mines: 16.2% of represented mine locations have already changed Köppen subtype, rising to 42.5% by late century under SSP5‐8.5. Divergent water trajectories are filtered through geology, infrastructure and lifecycle stage, indicating that adaptation requires monitored, scenario ...
