Here we present a catalog of high-precision relocated volcano-tectonic earthquakes, recorded by the seismic network managed by Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio Etneo (INGV-OE) from 2000 to 2024 and originating on Etna volcano area. To perform hypocentral location we adopt the NLL-SSST-coherence (NLL-SC; Lomax et al., 2022) probabilistic non-linear location method. NLL-SC is an advanced location method designed to improve precision across multiple scales. This is achieved through the correction of seismic wave travel times and the analysis of waveform similarity. We produced a 24-year catalog of hypocentral locations for Etna volcano, representing a previously unexplored dataset using high-precision location techniques. This comprehensive dataset not only will contribute to understanding the seismic behaviour of Etna volcano but also will plays a key role in ongoing monitoring and scientific research related to volcanic activity in the region.
