The fault needs to move about 6/16ths of an inch (9mm) per year to release the energy building up at the surface. This fault, called a “tectonic time bomb,” is about 74 miles long. The Hayward is one of three major fault zones of the San Andreas system that have produced large historic earthquakes in the San Francisco Bay Area (the others being the San Andreas and Calaveras). Running for nearly 74 miles through cities including Fremont, Hayward, Oakland, Berkeley, and Richmond, the Hayward Fault has the potential to wreak more havoc than most California faults.

However, as in 1906, well-constructed buildings on firm ground sustained much less damage.Towns in the East Bay suffered the most severe damage. In 2015, UC Berkeley researchers suggested that the Hayward fault may be connected to the nearby Calaveras fault, which, if true, would mean the potential for a … When the last quake struck the Hayward Fault in 1868, the Bay Area was sparsely populated. This event marked the end of a period of severely reduced creep on the southern part of the fault that began after the 1989 Loma Prieta, California, earthquake. According to the USGS, the real threat comes from smaller (about magnitude 7) earthquakes occurring on the Hayward fault, the Peninsula segment of the San Andreas fault, or the Rodgers Creek fault.
