We will examine Arizona’s earthquake risk by recognizing the statewide distribution of known faults and view seismic risk maps.  Then, we will consider the often spoken of (but little known in terms of detail), 1887 Sonoran earthquake through a review of historic damage pictures, as well as the geological features of the Pitaycachi Fault.  You will see how it has been studied more recently to analyze its future activity potential.  Finally, you will have the opportunity to review the first-person narrative accounts from more than 200 Arizona locations, nearby states, and Mexico.
