Statewide California focal mechanism catalog and stress model (1981-2021)
Description
Statewide California focal mechanism catalog and stress model (1981-2021) in pickle format, including: 1. Focal mechanism catalog (focmec_ca_final.pickle); 2. 2D stress model (stress_CA_2D.pickle); 3. 3D stress model (stress_CA_3D.pickle). Please use pickle package in python to open the datasets. Example: import pickle with open('stress_CA_2D.pickle', 'rb') as file: stress_CA_2D = pickle.load(file) print(stress_CA_2D.keys()) Here are the descriptions of the keys in each dataset ***** 1. Focal mechanism catalog: ***** num (total number of events); nc_sc (from NCSN or SCSN); ev_bl (earthquake or blast) year; month; day; hour; minute; second; time_year (time in year); time_utc (time in UTC format); evid; lat; lon; dep; mag; lat_reloc (latitude after relocation); lon_reloc (longitude after relocation); dep_reloc (depth after relocation); strike_orig (strike angle from original catalog); dip_orig (dip angle from original catalog); rake_orig (rake angle from original catalog); strike; dip; rake; uncer (uncertainty of nodel plane); npol (number of polarities); pol_misfit (polarity misfit); nspr (number of S/P amplitude ratio; spr_misfit (average log10(S/P) amplitude ratio misfit); prob (probability of solution close to real solution); azi_gap (maximum azimuth gap in station coverage); dip_gap (maximum take-off angle gap in station coverage); stdr (station distribution ratio); npamp (number of P-wave amplitude); pamp_misfit (log10(P-wave amplitude) misfit; nsamp (number of S-wave amplitude); samp_misfit (log10(S-wave amplitude) misfit; ftype (faulting type from -1 to 1); p_azi (P-axis azimuth); p_dip (P-axis plunge angle); t_azi (T-axis azimuth); t_dip (T-xis plunge angle); ***** 2. 2D stress model ***** ***** 3. 3D stress model ***** lat; lon; dep (only for 3D) s1_azi (azimuth of sigma1); s1_dip (plunge angle of sigma1); s2_azi (azimuth of sigma1); s2_dip (plunge angle of sigma1); s3_azi (azimuth of sigma1); s3_dip (plunge angle of sigma1); s11 (sigma11); s12 (sigma12); s13 (sigma13); s21 (sigma21); s22 (sigma22); s23 (sigma23); s31 (sigma31); s32 (sigma32); s33 (sigma33); SHmax (maximum horizontal stress azimuth); R (R value); friction (frictional coefficient); A (faulting style from 0 to 3); ftype (faulting style from -1 to 1); mslip_dev (mean slip deviation); s1_error (uncertainty of sigma1); s2_error (uncertainty of sigma2); s3_error (uncertainty of sigma3); R_error (R value uncertainty); A_error (A value uncertainty)
