Link to eruption of Etna

Although there are reports of an eruption at the time of the earthquake, most sources suggest that the volcano had been inactive since the destructive eruption of 1669. Analysis of the relationship between eruptions and earthquakes has found that earthquakes are followed by long periods without activity in the 'rift zones' that extend out to north and south from the summit. Estimates of Coulomb stress transfer due to the dyke intrusion in the rift zones associated with the 1669 eruption, suggest that this could have helped to trigger the 1693 earthquake, by increasing stress levels on the faults.[18]
