In 2012, USGS scientists said the fault was due for another magnitude 6.8 to 7.0 earthquake, with the California Geological Survey concurring, stating they believe there is a 31 percent chance of a magnitude-6.7 earthquake or greater along the Rodgers Creek-Hayward Fault in the next 30 years.
The 1868 Hayward earthquake occurred in the San Francisco Bay Area, California, United States on October 21. With an estimated moment magnitude of 6.3–6.7 and a maximum Mercalli intensity of IX ( Violent ), it was the most recent large earthquake to occur on the Hayward Fault Zone .
Route 238, consisting of State Route 238 (SR 238) and Interstate 238 (I-238), is a mostly north–south state and auxiliary Interstate highway in the San Francisco Bay Area of California. The southern segment is signed as SR 238 and is a divided multilane surface highway that runs parallel to the Hayward hills between I-680 in Fremont and I-580 ...
“It may not be associated with any of the major known, mapped fault lines.” ... All of California is at high risk for earthquakes. There is an 80.62% chance of a major earthquake within 31 ...
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
Probabilistic seismic hazard map. The earliest known earthquake in the U.S. state of California was documented in 1769 by the Spanish explorers and Catholic missionaries of the Portolá expedition as they traveled northward from San Diego along the Santa Ana River near the present site of Los Angeles. Ship captains and other explorers also ...
A full fault rupture, estimated to be around a 7.5 magnitude, could kill between 3,000 and 18,000 people, according to US Geological Survey and Southern California Earthquake Center.
The tunnel crosses the Hayward Fault at a nearly perpendicular angle 850 feet (260 m) from its western portal, and creep along the fault resulted in an offset of 13 inches (330 mm) by 2008. [6] The maximum credible earthquake (magnitude 7.0) predicted in studies would cause an offset of 7.5 feet (2.3 m).
