...Allan G. Lindh; David M. Boore abstract A reanalysis of the available data for the 1966 Parkfield, California, earthquake ( M L = 5 1 2 ) suggests that although the ground breakage and aftershocks extended about 40 km along the San Andreas Fault, the initial dynamic rupture was only 20 to 25 km...

..., a two-dimensional calculation. As an application of this technique, displacement-time histories were computed corresponding to those determined from accelerograms recorded during the 1966 Parkfield, California earthquake. On the basis of these comparisons, an effective stress of 25 bars, an average slip...

... by retaining the essential kinematic character of the faulting process. A computer program is developed to calculate ground motion from an assumed model of the 1966 Parkfield, California earthquake. Favorable agreement is obtained between the theoretically computed ground displacements and those derived from...

...David M. Boore; Allan G. Lindh; Thomas V. McEvilly; Wayne W. Tolmachoff Abstract Studies of P -wave travel times at a station within 0.5 km of the ground rupture associated with the Parkfield, California, earthquake of 1966 show no systematic variations for a time period of 7 months before...

...J. P. Eaton; M. E. O'Neill; J. N. Murdock abstract Hypocenters and magnitudes of more than 600 aftershocks of the 1966 Parkfield-Cholame earthquake were determined from recordings of a dense network of portable seismograph stations operated in the epicentral region from 3 to 82 days after the main...

...M. D. Trifunac; D. E. Hudson Abstract During the 1966 Parkfield, California, earthquake a strong motion accelerograph and an adjacent seismoscope were located essentially at the causative fault. The accelerograph component parallel to the fault malfunctioned and left no recorded trace...

...Thomas J. Fitch abstract A high sensitivity microearthquake recording station was established 10 km from the epicenter of the magnitude 5.5 Parkfield earthquake of June 28, 1966. Beginning 43 hours after the main shock, an hourly average of 22 microaftershocks was recorded for a period of 13 days...

...Stewart W. Smith; Max Wyss ABSTRACT Immediately following the 1966 Parkfield earthquake a continuing program of fault displacement measurements was undertaken, and several types of instruments were installed in the fault zone to monitor ground motion. In the year subsequent to the earthquake...

...Francis T. Wu Abstract The Parkfield earthquake of June 28, 1966 (04:26:12.4 GMT) is studied using short-period and long-period teleseismic records. It is found that (1) M b = 5.8 and M s = 6.4 as compared to M b = 5.4 and M s = 5.4 for the foreshock (04:08:54), (2) both the Rayleigh and Love wave...

...S. T. Algermissen; Samuel T. Harding Abstract S-wave polarization studies of the Parkfield, California earthquake of June 28, 1966, indicate that a type II or double couple focal mechanism best fits the available data. The direction of greatest stress derived from the S-wave solution is in general...

...William K. Cloud Abstract The isoseismal map indicates that the main shock of the Parkfield, California earthquake series on June 27, 1966 was felt over an area of approximately 20,000 square miles, and that the maximum Modified Mercalli scale intensity of VII was limited to a small area near...

...G. F. Murray Abstract Data is presented for all the June 1966 Parkfield, California, earthquakes that were recorded by five strong motion accelerographs in the Shandon-Cholame area south of Parkfield. The instrument array is generally transverse to the fault, intersecting it just north...
