  abstract = {{C}ontinuous seismic monitoring of volcanoes is challenging due to harsh environments and associated hazards. {H}owever, the investigation of volcanic phenomena is essential for eruption forecasting. {I}n seismo-volcanic applications, distributed acoustic sensing ({DAS}) offers new possibilities for long-duration surveys. {W}e analyse {DAS} strain rate signals generated by volcanic explosions and tremor at {S}tromboli volcano ({I}taly) recorded along 1 km of dedicated fibre-optic cable. {W}e validate {DAS} recordings with colocated nodal seismometers. {C}onverting node measurements to strain rate, we observe a perfect match in phase between {DAS} and node waveforms. {H}owever, {DAS} amplitudes appear to be around 2.7 times smaller than those of node records, which we explain as due to the inefficient ground-to-fibre strain transfer in the loose cable. {W}e invert time delays between strain rate waveforms and confirm that the {DAS} enables us to retrieve a dominant and persistent seismic source in the proximity of active craters. {T}his stable source location is confirmed by node array analyses. {D}espite an observed high noise level of strain rate signals outside a range of 2-15 {H}z, our results demonstrate the potential of this new technology in monitoring volcanic areas.},
