The probabilistic seismic hazard maps of the Italian national territory are represented by shaking parameters on a regular grid spaced by 0.05° and using two shaking parameters, PGA (horizontal peak ground acceleration) and Sa(spectral acceleration). Maps in peak ground acceleration (PGA) are evaluated for different probabilities of exceedance in 50 years (9 probabilities, from 2% to 81%). For each evaluation it is available the distribution of the 50th percentile (median map, which is the reference...

The Global Historical Earthquake Archive (GHEA) provides a complete account of the global situation in historical seismology for large earthquakes, as in 2013. From GHEA, the Global Historical Earthquake Catalogue (GHEC) was derived a world catalog of earthquakes for the period 1000-1903, with magnitudes of Mw7 and over.

IPSI is a georeferenced repository of contemporary stress indicators. It contains horizontal stress orientations inferred from borehole breakout data, earthquake focal mechanism data, fault data, overcoring data.

The Advanced Laboratory of Historical Seismology (CFTILab), was designed with two distinct but complementary targets. The first target was to make available to a wide specialist and non-specialist public – scholars, civil protection officers, teachers, students, professionals, simple onlookers – the IT tools that today allow the analysis of the data provided by the Catalogue of Strong Earthquakes in Italy in its most advanced version, namely CFTI5Med (http://storing.ingv.it/cfti/cfti5/). In addition to making it possible to...

ITACA is the ITalian ACcelerometric Archive of waveforms recorded by the National Accelerometric Network (RAN, Rete Accelerometrica Nazionale), operated by the Italian Civil Protection Department - Presidency of the Council of Ministers (DPC), the National Seismic Network (RSN, Rete Sismica Nazionale), operated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), and regional and international networks operated by various providers. ITACA 3.1 contains more than 45,000 waveforms of 1,946 seismic events with magnitude greater than...

ISMD is the real-time strong motion database of INGV since 2012. The web portal was designed and built in 2011 in cooperation between INGV Milan department and the National Earthquake Center, CNT (nowadays ONT). In the institutional context, the ISMD project represented a shared path to arrive at the regularization and homogeneity of the collection, treatment and distribution of the INGV accelerometric data. For each earthquake with epicenter located on the national territory with local...

ESM, the Engineering Strong-Motion Database, provides a set of facilities to search, select, download and analyse ground-motion data and associated metadata. The waveforms contained in ESM are relative to events with magnitude ≥ 4.0, mainly recorded in the European-Mediterranean regions and the Middle-East. ESM is targeted to applied seismologists, earthquake engineers, professional engineers, geologists, and policy makers. ESM main features are: Access to authoritative strong-motion data and metadata; Manual processing and quality check of waveforms;...
