Stress measurements for 42 Mw 4.0-5.4 earthquakes during the 2019 Ridgecrest earthquake sequence

The csv file “Ridgecrest_table2_v1.csv” contains measurements of apparent stress, stress parameter, and corner frequency.

EvtID:             Earthquake’s Event ID in Southern California Earthquake Data Center (SCEDC, https://scedc.caltech.edu).

Mw:                Moment magnitude

AST:               Apparent stress measurements in MPa using a time domain algorithm.

AST_STD:    Standard deviation of AST in log10 units.

ASF:               Apparent stress measurements in MPa using a frequency domain algorithm. Station terms have been corrected.

ASF_STD:    Standard deviation of ASF in log10 units.

Brune:           Stress parameter or Brune’s stress drop in MPa

Brune_STD: Standard deviation of ASF in log10 units. Note that the uncertainty is estimated using a bootstrap approach.

Fc:                  Corner frequency of the geometric mean source spectra

Fc_STD:        Standard deviation of Fc in log10 units. Note that the uncertainty is estimated using a bootstrap approach.

ASF_sub:     Apparent stress measurements in MPa using a frequency domain algorithm. Unlike ASF, only the stations with station terms less than 3 are used. No correction for station terms.

ASF_stack:  Apparent stress measurements in MPa using the geometric mean source spectra.

Depth:           Centroid depth in km

Vs:                  S wave velocity at the centroid depth in km/s

Density:        Density at the centroid depth in Mg/m³
