About us…

The Mineralogical Society of Southern California is dedicated to the dissemination of a general knowledge of the mineralogical and related earth sciences through the study and collecting of mineral specimens. Organized in 1931, it is the oldest mineralogical society in the western United States.
The MSSC is a scientific non-profit organization that actively supports the Pasadena City College Geology Department, its associated Dana Club,, and the Field Science Scholarship Fund. Support is also given to the San Bernardino County Museum of Natural History and Mindat.
The MSSC is affiliated with the California Federation of Mineralogical Societies and American Federation of Mineralogical Societies.

About the Program: Why Study Faults and Earthquakes?  Presented by Chuck Houser

Few if any California residents have never heard of the San Andreas Fault.  In fact, most Californians live within 30 miles of an active fault. But what exactly is an active fault?  Not surprisingly, the State not only has a very specific definition, but also a set of laws that come to bear when developing near an active fault.  For this reason, as well as the safety of the public, faults in developed areas and areas planned for development must be evaluated and their activity characterized.

This presentation will outline the process used to locate, evaluate, and characterize faults. Three significant Southern California earthquakes will be highlighted: M 6.6 Superstition Hills Earthquake of November 24, 1987; M 7.3 Landers Earthquake of June 28, 1992; and M 7.2 Sierra-El Mayor (Easter Sunday) Earthquake of April 4, 2010.
