  abstract = {{R}ecent developments in {D}istributed {A}coustic {S}ensing ({DAS}) have greatly expanded our capabilities for dense geophysical instrumentation by tapping into existing (but unused) fibre-optic telecommunica-tion networks. {L}everaging these so-called 'dark fibres' permits an extremely rapid deployment of thousandsof vibration sensors over distances of several tens of kilometres, which is ideal for rapid postseismic responseefforts. {H}ere we report on the use of dark-fibre {DAS} for monitoring of the aftershock sequence of the 2019-11-11 {M}w4.9 {L}e {T}eil, {F}rance earthquake. {T}hrough comparison with the local seismometer network, we assess the capabilities of the {DAS} array to detect and locate small-magnitude seismic events. {L}ikely owing to cabledeployment and {DAS} sensing characteristics, we find that the {DAS} noise floor is up to 3 orders of magnitudehigher than that of nearby seismometers, which greatly inhibits the detection and analysis of the low-energyevents. {H}owever, locating a selected aftershock with {DAS} yields an accuracy and precision that is comparableto that of the seismic network, even though the {DAS} array has a relatively unfavourable geometry. {B}ased onthese observations we provide a number of recommendations for routinely incorporating {DAS} into postseis-mic response protocols, and for optimal use of {DAS} alongside conventional seismic instrumentation.},
