Methodology
  • Amplitude ratio was calculated for each pair of waveforms that passed signal to noise threshold and cross correlation threshold tests (SNR > 3 and CC > 0.6) and averaged across channels if more than one component passed both data quality tests. Amplitude ratios were also averaged across station measurements where more than one was available. We use a least-squares inversion to determine relative magnitudes using the set of amplitude ratios. For a detailed description of methodology please refer to Gable & Huang 2023. To scale our relative magnitudes to a standard earthquake magnitude scale, we utilize a selection of 87 events with reported Mw (Sumy et al. 2014). We include these magnitudes in the least-squares inversion and we implement a weighting matrix that assigns a higher importance to these calibration events during the inversion. A detailed description of this part of the methodology can be found in the supplement to Gable & Huang 2023 Gable & Huang (2023) New Estimates of Magnitude-Frequency Distribution and b-Value Using Relative Magnitudes for the 2011 Prague, Oklahoma Earthquake Sequence (in review) doi: 10.22541/essoar.167591104.48272725/v1
Description
  • This dataset includes a catalog of events for the Prague, Oklahoma earthquake sequence with uncalibrated and calibrated relative magnitudes that are a product of the relative magnitude method (see Gable & Huang, submitted). Original earthquake catalog records for the combined catalog used in this analysis and the events used in the relative magnitude to absolute magnitude calibration process are a product of the following studies: Cochran, E.S., et al. (2020). Activation of optimally and unfavourably oriented faults in a uniform local stress field during the 2011 Prague, Oklahoma, sequence.
