The Hayward fault is a transform or strike-slip fault that moves sideways, rather than the more common faults that move up on one side and down on the other.
What boundary is the Hayward Fault?
The Hayward Fault is within the San Andreas Fault Boundary Zone between the North American Plate and the Pacific Plate . The Hayward fault is one of only a few dozen faults in the world that “creeps,” or slowly moves. Evidence of creep can be found from Pt. Pinole in the north to south Fremont.
What kind of fault is Hayward 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.
Is Hayward on a fault line?
| Date | 1864-05-21 | Region | South Hayward area | Mag. | 5.3 M la | MMI | VI |

Is the Hayward Fault part of the San Andreas Fault?
The Hayward fault is not our only fault. It is a member of the San Andreas Fault system that runs from the Gulf of California in the south, to Cape Mendocino in the north. The San Andreas Fault system forms the boundary between the North American and the Pacific tectonic plates.
How old is the Hayward Fault?
The 1868 Hayward Fault earthquake is a reminder of the tremendous power that lurks beneath the Earth’s surface in the San Francisco Bay region. The population at greatest risk from a Hayward Fault earthquake is 100 times greater than in 1868.
Is Walnut Creek on a fault line?
Concord city north of Walnut Creek has some building that are taller than 13 stories, it added. Northern California has two of the most hazardous faults — the Hayward-Rodgers Creek fault system and the San Andreas fault, which are most likely to have a damaging earthquake, according to the website of the USGS.
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.
Is Hayward safe?
Is Hayward, CA Safe? The C grade means the rate of crime is slightly higher than the average US city. Hayward is in the 42nd percentile for safety, meaning 58% of cities are safer and 42% of cities are more dangerous.
What is the most active fault line?
The Ring of Fire is the largest and most active fault line in the world, stretching from New Zealand, all around the east coast of Asia, over to Canada and the USA and all the way down to the southern tip of South America and causes more than 90 percent of the world’s earthquakes.
How far from a fault line is safe?
But first, what is considered a safe distance from a fault line? PhiVolcs recommends avoiding construction within five meters on each side of a fault trace . This is equivalent to a total width of 10 meters. This is considered the ideal “10-meter wide no-build zone” in the vicinity of a fault.
Where is the biggest fault line in America?
The New Madrid Seismic Zone (/ˈmædrɪd/), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri .
How do I know if my house is on a fault line?
How do I find fault or hazard maps for California? An online map of faults that includes California is in the Faults section of the Earthquake Hazards Program website. Choose the Interactive Fault Map, or download KML files and GIS shapefiles from the links on the page.
What areas will be affected by the San Andreas fault?
The cities of Desert Hot Springs, San Bernardino, Wrightwood, Palmdale, Gorman, Frazier Park, Daly City, Point Reyes Station and Bodega Bay rest on the San Andreas fault line.
What two states have never had an earthquake?
Florida and North Dakota are the states with the fewest earthquakes. Antarctica has the least earthquakes of any continent, but small earthquakes can occur anywhere in the World.
What is the biggest fault line in California?
The San Andreas Fault might be California’s most known fault line, but maybe not its most destructive. Recently, many faults have been discovered in the Sierra and Southern Cascades, an area active with smaller earthquakes and swarms over the last 150 years.
