The first report of the Commission constituted by California Governor George C. Pardee three days after the San Francisco Earthquake of April 18, 1906. This preliminary report, issued May 31, 1906, lays out "some of the more salient facts that have come to light" in the first weeks of the investigation. Scarce early scientific document on this notorious event.
