The goal was to be achieved by considering the most updated historical dataset and assessing homogenous magnitudes, with support from several institutions. This paper describes the SHARE European Earthquake Catalogue (SHEEC), which covers the time-window 1000-1899. It strongly relies on the experience of the European Commission project “Network of Research Infrastructures for European Seismology” (NERIES), a module of which was dedicated to create the European “Archive of Historical Earthquake Data” (AHEAD) and to establish methodologies to homogenously derive earthquake parameters from macroseismic data. AHEAD has supplied the final earthquake list, obtained after sorting duplications out and eliminating many fake events, and the most updated historical dataset. Macroseismic data points (MDPs) provided by AHEAD have been processed with updated, repeatable procedures, regionally calibrated against a set of recent, instrumental earthquakes, to obtain earthquake parameters. From the same data, a set of epicentral intensity-to-magnitude relations has been derived, with the aim of providing another set of homogeneous Mw estimates. Then, a strategy focussed on maximizing the homogeneity of the final epicentral location and Mw, has been adopted. Special care has been devoted also to supply location and Mw uncertainty. The paper focuses on the procedure adopted for the compilation of SHEEC and briefly comments on the achieved results.1318 289 - PublicationOpen AccessThe Estimation of Earthquake Parameters in Europe by Using Macroseismic Data: Testing the MEEP Program(2008-09-07)

M. W.; British Geological Survey ;Papaioannou, C.; ITSAK; ; ; ; ; ; In the frame of the NA-4 module of the European project NERIES, a specific task is devoted to the determination of earthquakes parameters from macroseismic data. On this regard, a new methodology, implemented in the program MEEP, has been developed by Musson et al. (see relevant presentation in this session). Here we present and discuss some tests performed by using the MEEP program in order to contribute to the setting up of the code and to validate the methodology itself. To this purpose, a set of earthquakes occurred in different regions of Europe and with different ranges of magnitude have been selected. In particular, the main aspects investigated here are: • reliability of estimates of epicentre location, magnitude and hypocentral depth compared with instrumental determinations; • comparison with epicentral parameters derived by using other methods based on macroseismic data; • sensitivity of the methodology to number and geographic distribution of available intensity data points (IDPs); • sensitivity to the calibration parameters requested by the program. Results of this analysis suggested some modifications of the program203 156 - PublicationOpen AccessSesame Project - Deliverable D04-04 - Report of the WP04 H/V Technique : Empirical Evaluation - Homogeneous Data Set of Noise and Earthquake Recordings at Many Sites(2003-07)

Three main topics are included in the Report: (a) The Standard Information Sheet (SIS) structure, (b) The SESAME Ascii Format (SAF) files, and (c) The SESAME SIS-database. The SIS compiled in this sub-task and SAF format adopted for all data, constitute a homogeneous data set to be processed for further scientific results in the framework of the WP04. In addition, the SIS-database is going to facilitate data selection and management.284 447 - PublicationOpen AccessA comparative study of a stochastic and deterministic simulation of strong ground motion applied to the Kozani-Grevena (NW Greece) 1995 sequence(2000-10)

Source parameters were calculated from empirical relations in order to check their reliability, in combination with the applied methodologies, to simulate future events. Strong ground motion from the Kozani mainshock (13 May, 1995, M w = 6.5) was synthesized by using both the stochastic method for finite-fault cases and the empirical Green’s function method. The latter method was also applied to simulate a Mw = 5.1 aftershock (19 May, 1995). The results of the two simulations computed for the mainshock are quite satisfactory for both methodologies at the frequencies of engineering interest (> ~ 2 Hz). This strengthens the idea of incorporating proper empirical relations for the estimation of source parameters in a priori simulations of strong ground motion from future earthquakes. Nevertheless, the results of the simulation of the smaller earthquake point out the need for further investigation of regional or local, if possible, relations for estimating source parameters at smaller magnitude ranges155 1033 - PublicationOpen AccessSeismic hazard assessment for Adria(1999-12)

The standard hazard map chosen by GSHAP represents PGA with a 475-year return period. Some other parameters, as the spectral acceleration and the uniform hazard response spectra for the main Adriatic towns, have been computed for a better representation of the regional hazard. The most hazardous area remains identified in the Cephalonia zone, where strong earthquakes frequently occur. The Southern Apennines are characterised by a slightly lower hazard, while the Adriatic Sea itself, the Poplain and the Apulian peninsula are almost aseismic.344 728
