Microseismic source parameters from induced seismicity in the Horn River Basin (British Columbia) (NERC Grant NE/R017956/1)
This data set contains seismic source parameters (magnitudes, corner frequencies, stress drops and their associated uncertainty) for 94 microseismic events linked to fault reactivation during hydro-fracturing operations in the Horn River Basin (British Columbia). The data presented here were derived from proprietary third party seismic data recorded on 2 arrays of 35 - 15 Hz GEO-OMNI-2400 borehole geophones each. These data were first reported in Adam G Klinger, Maximilian J Werner, Stress drops of hydraulic fracturing induced microseismicity in the Horn River basin: challenges at high frequencies recorded by borehole geophones, Geophysical Journal International, Volume 228, Issue 3, March 2022, Pages 2018–2037, https://doi.org/10.1093/gji/ggab458

Data Quality
From the proprietary dataset provided, we used a standard STA/LTA algorithm to select phase picks for events in which there were corresponding picks on all stations which corresponded to events with relatively high signal to noise ratios. Stress drops were calculated using a Brune model (Brune, 1970) and uncertainties are calculated using a bootstrapping technique. Brune (1970) was also used to estimate seismic moments which were fed into the seismic moment equation from Hanks and Kanamori (1979) to estimate the Moment magnitude. Finally, the stress drops were estimated using the Eshelby (1957) equation. Please see Klinger and Werner (2021) for full details on the method.
