The whole earthquake waveform data-set acquired by University of Wisconsin during the 1984 acquisition experiment, performed in the Campi Flegrei caldera, has been recovered, formatted and organized in a easy-accessible data archive. This archive represents a complete database of 3-component waveforms containing several hundreds microearthquakes recorded at Campi Flegrei, during the last bradiseismic crisis in the 1983-84. In addition to its relevance for earthquake location and velocity structure investigations this is actually the unique, digital data-base acquired during an unrest episode at Campi Flegrei caldera and it represents a valuable reference data set to be used for seismic hazard analyses during future crises. The whole waveform data base has been re-picked. This is because the data set has been strongly incremented, respect to the previous one, with the new recovered data, and possible heterogeneities of new with previous picks could bias the tomographic inversion results. This database can be used to better understand Campi Flegrei structure applying updated technique of analysis. It has been used to perform a tomographic analysis using an increased P- and S-phase dataset, with a re-location of some hundreds of earthquakes.
