Continuous "mole-track" running parallel to the strike of the fault indicates some E-W compression in addition to right-lateral faulting. Photo taken near Buhman Rd.

Small displacement ground cracks along main rupture near Cuttings Wharf Rd., south of Hwy. 12, taken the day of the earthquake. Displacement in this area grew to ~20 cm right-lateral by Monday, 8/25, due to afterslip.

Warren Hall on California State University East Bay's Hayward campus is scheduled to be demolished Aug. 17, 2013 for seismic safety reasons. The landmark building's implosion will produce energy similar to a small earthquake that can be used to study and map the nearby Hayward Fault. In partnership with the university, U.S.
