Here we utilise a dataset of repeating earthquakes which occurred between 2000 and 2019 along the transtensive Pernicana fault system on the northeast flank of Mount Etna, Italy, to investigate the fault structure, as well as the triggering mechanisms of the seismicity. By grouping the repeating earthquakes into families and integrating the seismic data with GPS measurements of ground deformation, we identify four distinct portions of the fault. Each portion shows a different behaviour in terms of seismicity, repeating earthquakes and ground deformation, which we attribute to structural differences including a segmentation of the fault plane at depth. The recurrence intervals of repeating earthquake families display a low degree of regularity which suggests an episodic triggering mechanism, such as magma intrusion, rather than displacement under a constant stress.</p> <p>&nbsp;</p> <p><strong>Dataset description</strong>:&nbsp;The&nbsp;dataset consists of a xls file with the main features of all the detected repeating earthquake families, which occurred during 2000 - 2019 along the Pernicana fault system&nbsp;on the northeast flank of Mount Etna (Italy). In particular, this file contains: a first sheet with the main features of all the families; a sheet per each family with information about all the earthquakes composing the family, as well as figures with waveforms and cross correlation matrices. The analysed earthquakes belong to the INGV Osservatorio Etneo earthquakes database (https://www.ct.ingv.it/).</p>
