Probabilistic seismic hazard models are usually grounded on a basilar statistical analysis of recent and historical seismicity, and only a small number of them also considers the local geodetic strain and the discrete seismogenic sources.

Here, we show some preliminary results about the connection between advanced statistical properties of seismicity, rock physics, tectonics and the mid-/long-term seismogenic potential. The role of local and global, spatial, and temporal clustering of seismic events is deeply analysed also with reference to local geodynamics and other routinely investigated features of seismicity, e.g., the b-value of the Gutenberg-Richter law.

Abstract
Probabilistic seismic hazard models are usually grounded on a basilar statistical analysis of recent and historical seismicity, and only a small number of them also considers the local geodetic strain and the discrete seismogenic sources. Nevertheless, a large amount of information is buried in spatial and temporal time series as well as in the geophysical properties of the different tectonic settings. Here, we show some preliminary results about the connection between advanced statistical properties of seismicity, rock physics, tectonics and the mid-/long-term seismogenic potential. The role of local and global, spatial, and temporal clustering of seismic events is deeply analysed also with reference to local geodynamics and other routinely investigated features of seismicity, e.g., the b-value of the Gutenberg-Richter law.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
