@format A data frame with columns:

I_D: The unique numeric identifier of the record.

EQ_MAG_ML: The ML magnitude was the original magnitude relationship defined by Richter and Gutenberg for local earthquakes in 1935.
EQ_MAG_MFA: The Mfa magnitudes are computed from the felt area, for earthquakes that occurred before seismic instruments were in general use.
EQ_MAG_UNK: The computational method for the earthquake magnitude was unknown and could not be determined from the published sources.
