The Seismicity of Ischia Island, Italy: An Integrated Earthquake Catalogue From 8th Century BC to 2019 and Its Statistical Properties

A review and systematically re-analysis of all the available data on the historical and instrumental seismicity has be performed to build an integrated earthquake catalog for Ischia with a robust characterization of existing uncertainties. Supported by new or updated macroseismic datasets, the existing catalogs (e.g. CPT15) have been significantly enriched. The instrumental catalog has been extended back by 6 years, homogenizing the estimated seismic parameters. The obtained catalog not only represent a solid base for future local hazard quantification, but also it provides the unique opportunity of characterizing the evolution of the Ischia seismicity over centuries. This new catalog is prone to analyse the spatial, temporal, and magnitude distributions of Ischia seismicity, as done in Selva et al. (2021).
