TABLE 5.3.-Locations and focal-mechanism parameters for selected earthquakes in the Coalinga-Kettleman Hills region

[ML, estimated local magnitude. for ML<1, estimate is based on coda magnitude (see Lee and Stewart, 1951); for ML>3, estimate is based on peak amplitude and associated period (see Eaton and others, 1970). focal-mechanism parameters: DA, dip angle; DD, dip azimuth]
