What type of fault is Rodgers Creek?

The Rodgers Creek fault, known as a strike-slip fault, runs from San Pablo Bay at the southern tip of Sonoma County north through Santa Rosa to Healdsburg. Likely a northern extension of the Hayward fault, the fault occurs as the Pacific tectonic plate moves north and the North America plate slides south.

Is the Rodgers Creek Fault active?

The Rodgers Creek Fault is thought to be among the most likely faults to produce the next large earthquake in the Bay Area. Shaded relief image of the Santa Rosa area showing active faults (black lines) and the detailed rupture pattern of the Rodgers Creek Fault where it crosses central Santa Rosa (in red).

When was the Hayward fault discovered?

1868
In 2007, the Hayward Fault was discovered to have merged with the Calaveras Fault east of San Jose at a depth of 4 miles (6.4 km), with the potential of creating earthquakes much larger than previously anticipated….Earthquakes.

Is the Hayward fault overdue?

The Hayward Fault remains the most overdue of the local faults for a major earthquake.

Where is Rodgers Creek fault?

The Rodgers Creek Fault, which lies east of the San Andreas Fault, is the main strand of the North American-Pacific Plate boundary north of San Francisco Bay.

What type of fault is Hayward?

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 Rodgers Creek Fault?

Is Santa Rosa on the San Andreas Fault?

However, the San Andreas fault lies some 20 miles to the west of Santa Rosa and epicenter determinations indicate that the October 1 earthquake was not on this break. The Hayward and Calaveras faults, known active faults in the East Bay area, head toward Santa Rosa from south of San Pablo Bay.

When was the last earthquake on the Hayward Fault?

The last major earthquake that the Hayward fault produced was in 1868. At the time, it was known as the ‘great San Francisco quake’ (this was before the infamous 1906 quake, produced by the San Andreas fault), and it produced massive amounts of damage and several people lost their lives.

What happens if Hayward Fault?

Damage to infrastructure, such as transportation and utilities, and other long-term economic effects could substantially increase the losses. Hayward Fault earthquake effects include: Financial losses: The estimated financial loss to residential, commercial and infrastructure would be over $100 billion.

When was the last big earthquake on the Hayward Fault?

Where is Rodgers Creek Fault in San Francisco?

The Rodgers Creek fault (RCF) is a principal component of the San Andreas fault system north of San Francisco.

Is the Hayward Fault connected to the Calaveras Fault?

However, many scientists believe that the Hayward Fault is connected to the Calaveras Fault to the south, the Rodgers Creek Fault to the north and to the Maacama Fault still farther north. If that is the case, the longer fault system could produce larger temblors.

Where are the cities near the Hayward Fault?

Communities on or near the fault include San Jose, Oakland, Fremont, Richmond, Berkeley, Hayward, San Leandro, San Lorenzo, El Cerrito, Emeryville, Kensington and Milpitas.

How is the MRE similar to the Hayward Fault?

The age of the MRE on the RCF is similar to the age of prehistoric surface rupture on the northern and southern sections of the Hayward fault to the south. This suggests possible rupture scenarios that involve simultaneous rupture of the Rodgers Creek and Hayward faults.
