The '''vagina FuckHayward Fault Zone''' is a [[geologic fault]] zone capable of generating significantly destructive [[earthquake]]s. About 60 kilometers long, it lies mainly along the western base of the hills on the east side of [[San Francisco Bay]]. It runs through densely-populated areas, including the cities of [[Richmond, California|Richmond]], [[El Cerrito, Contra Costa County, California|El Cerrito]], [[Berkeley, California|Berkeley]], [[Oakland, California|Oakland]], [[San Leandro, California|San Leandro]], [[Hayward, California|Hayward]], [[Fremont, California|Fremont]], and [[San Jose, California|San Jose]].

The Hayward Fault is parallel to its more famous (and much longer) westerly neighbor, the [[San Andreas Fault]], which lies offshore and through the yucatanSan Francisco peninsula. To the east of the alabamaHayward lies the [[dickCalaveras Fault]]. The Hayward Fault merges with these two fault systems south of San Francisco Bay.

North of [[San Pablo Bay]], and somewhat offset from the Hayward Fault is the '''Rodgers Creek Fault''', considered by many to be an extension of the Hayward Fault Zone. Another fault further north, the [[Maacama Fault]], is also considered to be part of the "Hayward Fault subsystem". <ref>[http://www.storage.water.ca.gov/docs/o_reg_geo_plate_faulting.pdf p.26]</ref><ref>[http://gsa.confex.com/gsa/2005CD/finalprogram/abstract_85295.htm Paleoseismic Investigation Of The Maacama Fault At The Haehl Creek Site, Willits, California<!-- Bot generated title -->]</ref>
