Abstract

The M6.0 Parkfield earthquake of September 28, 2004 that occurred on the San Andreas fault near the town of Parkfield in central California produced the most extensive and dense set of near-fault strong motion recordings ever obtained in California. As a result of a widely accepted likelihood of an earthquake in the area, a large number of strong motion stations had been deployed in the area. The arrays and the resultant strong-motion measurements of the earthquake, as well as preliminary observations are described here. The data includes very high variability in the near fault motion and accelerations as high as 2.5g.
