+ The main goal of this WP is the creation of a qualified waveform archive that will collect, in a uniform format (SEED), the data of all the available seismic stations in the region. It will be the first example of complete integration of permanent networks (National Seismic Network; MedNet; Peloritani Local Network), temporary deployments (both mobile network from INGV CNT and INGV CT) and OBS data, that hopefully will become a standard for INGV seismic experiment. We will compute refined hypocentral locations to define seismogenic structures inside the Messina Strait and in the surrounding region especially in the Tyrrhenian and Ionian sea. We will evaluate the improvement introduced by the use of OBS on the seismic detection and on earthquakes location. 3 Test site 2 Messina Strait | WP2.2 Integrated seismic data bank and refined earthquake location to define seismogenetic structures Meeting 24 Marzo Roma OBJECTIVES

+ Starting from February 2008 INGV CNT (Rome) and INGV Catania data center are connected in real time via seedlink; we converted all the continuous seismic recordings of the temporary stations in standard format SEED; we generated the dataless of the temporary stations; the dataset has been formatted and structured following the standard of the INGV national databank (EIDA); the temporary stations codes have been registered at ISC (International Seismological Center).
