Fault dip vs shear stress gradient
In the brittle regime, faults tend to be oriented along an angle of about 30 relative to the principal stress direction. This empirical Andersonian observation …

Global versus local clustering of seismicity: Implications with earthquake
prediction
Clustering is the essence of earthquake occurrence. Although not exhaustive, our analysis is a first attempt to understand what information may be hidden in partial, …

The impact of faulting complexity and type on earthquake rupture dynamics
We analysed the earthquake double-couple as a function of the faulting type. Here we show that it impacts the moment tensors of earthquakes: thrust-faulting events are characterized by higher double-couple components with respect to strike-slip- and normal-faulting earthquakes.

Correlation between seismic activity and tidal stress perturbations highlights growing instability within the brittle crust
Faults become more and more responsive to stress perturbations as instability mounts. We utilize this property in order to identify the different phases of the seismic cycle.

Scaling properties of seismicity and faulting
In this work, a model for describing the size-frequency scaling and the temporal evolution of seismicity is proposed starting from simple assumptions. The parameter describing how the number of earthquakes decreases after a major seismic event, p, turns out to be positively correlated to the exponent of the frequency-size distribution of seismicity, b, and related to tectonics.

Variable seismic responsiveness to stress perturbations along the shallow section of subduction zones: the role of different slip modes and implications for the stability of fault segments
Assessing the stability state of fault interfaces is a task of primary interest not only for seismic hazard, but also for understanding how the earthquake machine works

Earth’s gradients as the engine of plate tectonics and earthquakes
The processes occurring on the Earth are controlled by several gradients. The surface of the Planet is featured by complex geological patterns produced by both …
