Hayward Fault and Rogers Creek Fault Found to be Connected

This news might seem obscure to most of you but it is of great interest to me.

The Hayward fault is often said to be the most dangerous earthquake fault in the San Francisco bay area. It extends northwards along the east side of the bay, through Hayward, Oakland and right under the UC Berkeley campus. To the north, the Rogers Creek fault extends up through the Napa valley. The north end of the Hayward fault and the south end of the Rogers fault are in San Pablo bay.

Well, recently geologists determined that it's all one fault that extends completely across the bay. That makes it a much bigger fault and if anything, more dangerous.

I remember taking an introductory geology class in the 1990's and suggesting to the instructor that maybe the two faults were connected, due to their ends lining up so well on the earthquake fault map. He didn't think much of the idea at the time.

It is always nice to be proven right.

I have a lot of interest in the fault lines and possible quakes because we are overdue for a devastating event and are constantly warned to be prepared.  I am afraid anything we can do as individuals is a sick joke compared the damage that will be done and what can be a long wait for help.  

The Cascadia subduction zone is a different one from the fault line of which you speak, but it runs from
British Columbia's Vancouver Island to California's Cape Mendocino and when this goes it creates a tsunami in the northwest of the US and Japan.

Here is another explanation, including the area that may experience landslides and liquefication in California and a picture of the damaged Cypress Freeway in Oakland.  You can see the twist in the bridge.

The Winchester house in your area is tied to the 1906 Earthquake.

---The 1906 Earthquake

If Mrs. Winchester took precautions to enlist the aid of friendly spirits, they were nevertheless unable to protect her from the Great San Francisco Bay Area Earthquake of 1906. The quake registered 8.3 on the Richter scale and stretched all the way from Oregon to Los Angeles. It severely damaged Mrs. Winchester’s home, toppling the seven-story Observation Tower and some cupolas. She herself was badly shaken, trapped in her favorite Daisy Bedroom near the front of the mansion. It took servants several hours to locate her and then pry open the bedroom door and rescue her. end quote

I am not sure of the standard for this forum.  Some people object to how I see one thing related to another.  Please, let me know if this is wrong in this forum.
