    Description: An objective regionalization of the Mediterranean basin is derived from a tomographic study based on the fundamental mode of Rayleigh waves. The database is formed by seismic wavetrains recorded at very-broadband stations belonging to MedNet and other cooperative stations, located in the Mediterranean area. The data treatment consists of application of spectral filtering techniques aimed to determine path-averaged group velocities, computation of local group velocity maps for some periods and classification of the studied area in several homogeneous regions according to Principal Component Analysis (PCA) and Average Linkage (AL) algorithms. Finally, the group velocity dispersion curves representing each homogeneous region are compared and possible correlation between these regions and seismotectonic and structural characteristics are discussed.

    Description: Within the European Project NERIES, sponsored by the European Commission in the frame of the Specific Programme "Structuring the European Research Area", the NA4 module is devoted to establish a distributed archive of historical earthquake. NA4 objectives are to establish the required tools leading to the compilation of a comprehensive, digital macroseismic intensity database for the largest European earthquakes (with magnitude 〉=5.8 at least) and a validated and homogeneous European parametric earthquake catalogue for M〉=5, to serve as an authoritative reference for users involved in the assessment of seismic hazard and risk. The main focus is devoted to the time-window before 1900. Some highlights about the whole NA4 project, actual state of the initiatives undertaken in the Iberian Peninsula to contribute to it and future developments are presented.

    Description: The general purpose of the present paper is to summarize the state-of-the-art of historical earthquake knowledge and research in the Iberian Peninsula, giving an account of the main references, the historical developments and the present situation of earthquake catalogues. The most representative historical works for compiling earthquake data (catalogues) up to 1985 are referred together with those of more recent investigations carried out in Spain and Portugal for the period 1985-2003. Existing databases on historical seismicity are presented, mentioning the most important achievements in relation to quality of information.
