In most cases of reservoir-induced seismicity, seismicity follows the impoundment, large lake-level changes, or filling at a later time above the highest water level achieved until then. We classify this as initial seismicity. This ‘‘initial seismicity’’ is ascribable to the coupled poroelastic response of the reservoir to initial filling or water level changes. It is characterized by an increa...

Existing loading protocols for quasi-static cyclic testing of structures are based on recordings from regions of high seismicity. For regions of low to moderate seismicity they overestimate imposed cumulative damage demands. Since structural capacities are a function of demand, existing loading protocols applied to specimens that are representative of structures in low to moderate seismicity re...

The observation of foreshocks preceding large earthquakes and the suggestion that foreshocks have specific properties that may be used to distinguish them from other earthquakes have raised the hope that large earthquakes may be predictable. Among proposed anomalous properties are the larger proportion than normal of large versus small foreshocks, the power law acceleration of seismicity rate a...

Volcano eruption forecast remains a challenging and controversial problem despite the fact that data from volcano monitoring significantly increased in quantity and quality during the last decades. This study uses pattern recognition techniques to quantify the predictability of the 15 Piton de la Fournaise (PdlF) eruptions in the 1988-2001 period using increase of the daily seismicity rate as a...

Continental intraplate seismicity seems often episodic, clustered, and migrating. The observed seismicity shows both spatial clustering in seismic zones and scattering across large plate interiors, temporal clustering followed by long periods of quiescence, and migration of seismicity from one seismic zone to another. Here, we explore the complex spatiotemporal patterns of intraplate seismicity...

We investigate on the capability of the strongest earthquakes to modify significantly the seismicity in a wide spatio-temporal window. In particular, we show that the strongest earthquakes of last century were probably able to influence the seismicity at large spatio-temporal distances, extending their reach over thousand of kilometers and decades later. We report statistically significant diff...

We describe a model to estimate event rates of a non-homogeneous spatio-temporal Poisson process. A Bayesian change point model is described to detect changes in temporal rates. The model is used to estimate whether a change in event rates occurred for a process at a given location, the time of change, and the event rates before and after the change. To estimate spatially varying rates, the spa...
