The catalogue covers the time span from July 1 to September 30, 1988. It lists earthquakes with magnitude greater than/equal to 1.8 located onshore and in the sea within circa 5 km from Gran Cratere of Vulcano, Italy. These seismic data shed light on the unrest that disrupted the quiescence state of the volcano in 1988. In particular, a seismic swarm occurred from August 9 to 15, with typical faulting-like earthquakes achieving the maximum magnitude 2.5. For each earthquake the catalogue provides the hypocentral parameters (UTC origin time, latitude, longitude, and depth in km), duration magnitude, energy (using the magnitude–energy relationship computed for Italian earthquakes by Di Filippo and Marcelli, 1950), and strain release (square root of energy; in ergs).

A group of people actively participated to the seismic monitoring of the Aeolian Islands in the 1980s, contributing in various forms to the acquisition of information. The members of this group were staff of Istituto Internazionale di Vulcanologia of the Italian Consiglio Nazionale delle Ricerche (CNR). In addition to the listed contributors of the catalogue, thanks to Professor Antonio Montalto, together with the technicians Angelino Biviano, Mario Marturano, and Salvatore Velardita.
