Probabilistic moment tensor inversion for hydrocarbon-induced seismicity in the groningen gas field, the netherlands, Part 2: Application

Recent developments in the densification of the seismic network covering the Groningen gas field allow a more detailed study of the connection between induced seismicity and reactivated faults around the gas reservoir at 3 km depth. With the reduction of the average station distance from 20 km to 4–5 km, a probabilistic full-waveform moment tensor inversion procedure could be applied, resulting in both improved hypocenter location accuracy and full moment tensor solutions for events of M ≥ 2:0 recorded in the period 2016–2019. Hypocenter locations as output from the moment tensor inversion are... Mehr ...
