Marzocchi 2 1 INGV (Istituto Nazionale di Geofisica e Vulcanologia), Rome, Italy 2 Università di Napoli, Federico II, Naples, Italy Motivation. The most accurate short-term earthquake forecasting models describe the seismicity as a combination of two main sources: a constant external driving force (the tectonic plate loading) and an intrinsic self-exciting process (the occurrence of an event increases the frequency of the next events). Earthquakes that are dependent on those preceding them are defined as triggered earthquakes (they cluster in both space and time), while independent events (the initiating event of each cluster, together with isolated events) are defined as background earthquakes. Although the occurrence of space-time clusters is a general feature of seismicity, several regional and global studies have suggested that seismic clustering properties (triggering capability, temporal and spatial extent of the seismic sequences etc.) may be controlled by the tectonic regime. Such evidence is usually used to claim for a calibration of the short-term
