Where is the Hayward Fault in Oakland?
The Hayward Fault is a major geologic fault line that runs through Oakland and the rest of the East Bay. It runs approximately along the base of the hills, following I-580 and Highway 13. Over the last 1,000 years, the fault has had major earthquakes about every 140 years.
Where can I see the Hayward Fault?
Near San Jose the Hayward Fault branches off the Calaveras and continues north along the foot of the East Bay Hills. For residents of the East Bay, the Hayward fault is of particular concern because it runs through many cities such as San Jose, Fremont, Hayward, San Leandro, Oakland, Berkeley, El Cerrito and Richmond.
How bad is the Hayward Fault?
The Hayward fault activity is capable of generating destructive earthquakes. This fault, called a “tectonic time bomb,” is about 74 miles long. History shows that five large earthquakes on the Hayward fault have occurred on average every 150 years—last being in 1868.
Where are the fault lines in the Bay Area?
The Hayward fault runs through the East Bay hills from Richmond to San Jose. Nearly 3 million people currently live along the fault. According to U.S. Geological Survey (USGS), the Hayward fault is a “tectonic time bomb,” set to go off anytime now.
Is the Hayward Fault moving?
The Hayward Fault is actively moving, year-by-year. This characteristic is unlike that of other earthquake faults such as the San Andreas Fault, which is “locked” between major earthquakes.
What’s the biggest fault line in America?
The New Madrid Fault
The New Madrid Fault extends approximately 120 miles southward from the area of Charleston, Missouri, and Cairo, Illinois, through Mew Madrid and Caruthersville, following Interstate 55 to Blytheville, then to Marked Tree Arkansas.
Is the Hayward Fault a transform fault?
The Hayward Fault is an offset of the San Andreas Fault system that dominates the landforms of eastern San Francisco Bay. This slip slide motion is called a transform fault. The Hayward Fault is within the San Andreas Fault Boundary Zone between the North American Plate and the Pacific Plate.
Where are the California fault lines?
The San Andreas Fault is the sliding boundary between the Pacific Plate and the North American Plate. It slices California in two from Cape Mendocino to the Mexican border. San Diego, Los Angeles and Big Sur are on the Pacific Plate. San Francisco, Sacramento and the Sierra Nevada are on the North American Plate.
Is the Hayward Fault overdue?
This quake was not large enough to trigger to new ShakeAlert system, which would theoretically have sent warnings to people’s cellphones ahead of the shaking. The Hayward Fault remains the most overdue of the local faults for a major earthquake.
How often does the Hayward Fault rupture?
about 150 years
USGS scientists have found evidence for 12 quakes on the southern Hayward Fault during the past 1,900 years. Notably, the last six quakes (in 1134, 1317, 1475, 1629, 1725, and 1868) occurred at intervals of 95 to 183 years, with an average interval of about 150 years.
Where can I see the San Andreas Fault in the Bay Area?
The San Andreas Fault begins near the Salton Sea, runs north along the San Bernardino Mountains, crosses Cajon Pass, and then runs along the San Gabriel Mountains east of Los Angeles. The mud pots near the Salton Sea are a result of its action, but your best bet to see the Southern San Andreas Fault is at Palm Springs.
What type of fault is the Hayward fault?
right-lateral strike-slip fault
Detailed Mapping of the Hayward Fault It is a right-lateral strike-slip fault, meaning that motion along it is mainly horizontal, so that objects on the opposite side of the fault from the viewer will move to the viewer’s right as slip occurs.
Where is the Hayward Fault in California located?
Dr. Sue Ellen Hirschfeld, previously a Professor of Geology at California State University, East Bay, has an informative website with lots of photos and interesting places to visit. It is divided into small regions from Fremont to San Pablo Bay. A shaking intensity map for the 1868 Hayward fault earthquake. USGS
How many people will be injured by a Hayward Fault earthquake?
Injuries: City of San Francisco Fire Department estimates that, after another major earthquake of 6.8 magnitude, there will be 10 feet of glass in downtown San Francisco on the streets. USGS forecasts 18,000 non-lethal injuries. Jobs: A major earthquake along the Hayward Fault would affect more than one-third of current jobs.
Where are the fault lines in San Francisco?
These include the Hayward Fault running through East Bay communities, the San Andreas Fault running from below San Jose through San Mateo and San Francisco Counties and extending into Marin County, the San Gregario Fault cutting across Western San Mateo County, and the Concord and Calavaras Faults in Contra Costa and Eastern Alameda County areas.
Is there a chance of an earthquake in the Bay Area?
There is a 3 out of 4 chance of a damaging earthquake in the Bay Area in the next 30 years. USGS names the biggest actors as the San Andreas Fault, the Calaveras Fault, and the Hayward Fault. Bay Area residents also need to be prepared for aftershocks.
