Strain-rate of the local February (panel a) and April (panel b) seismic events detected on the entire interrogated fiber. The left panels show the multiple arrivals including the first P- and S-waves. The middle and right panels focus on the first P- and first S-arrivals, respectively. The curves on the waveforms indicate the results of the semi-automated first arrival picking. Panel (a): the February event is located about 10 km away from the SLS geothermal site and has a magnitude of ML 1.5. The horizontal axis indicates seconds after 2022.02.09 05:51:30.7 (UTC). Panel (b): April event. The horizontal axis shows seconds after 2022.04.22 13:26:11.8 (UTC)
