"Earthquakes in California in 1893," Charles D. Perrine (Washington: Government Printing Office,) 1894. The item lists chronologically all reported earthquake activity in the state. Of note was a large earthquake in the San Fernando oil region in present-day Santa Clarita. The item is in a modern paper wrapper with a photocopy of the title page on the front. Aside from some light water stains in the top right corner and light browning, the condition is good.
