...Robert M. Hamilton abstract Aftershocks of the magnitude 6.5 earthquake of 9 April 1968 near Borrego Mountain, California, were recorded by 20 portable seismographs during a two-month period beginning two days after the main shock. Near the end of the recording period, three explosions were set off...

...Robert S. Hart; Rhett Butler abstract The wave-form correlation technique (Hart, 1975) for determining precise teleseismic shear-wave travel times is extended to two large earthquakes with well-constrained source mechanisms, the 1968 Borrego Mountain, California earthquake and the 1973 Hawaii...

The historic earthquakes of interest occurred in 1937, 1942, and 1954. We use the 1968 Borrego Mountain, 1969 Coyote Mountain, and 1987 Elmore Ranch earthquakes as calibration...
