The firsthand reports were most abundant for the shocks felt at 1, 2, and 4 hours before the main shock which were later labeled the predawn, dawn, and sunrise shocks. The predawn event shook residents of San Francisco (MM II – III), San Jose (MM IV), and Santa Cruz (MM IV). The dawn shock was felt in those locales plus Fort Tejon and possibly the Carrizo Plain. The sunrise shock was felt in San Francisco (MM III), Monterey (MM IV), and Visalia (MM II – III). Sacramento and Los Angeles did not report any of these events.
