The last “big one”-level movements in California’s recorded earthquake history are the 1857 earthquake in the central third of the San Andreas and the 1906 earthquake in the northern third...that’s not to say there haven’t been major earthquakes since then.
The 1989 San Francisco-area earthquake and the 1994 Northridge earthquakes, for instance, were both devastating and destructive shocks...
The impact that a large earthquake has, whether it’s a 6.5 or an 8.0, largely depends on the proximity to urbanized areas.
The southern San Andreas is particularly of concern for experts when looking at places that are overdue for an earthquake above a 7.5, impacting areas like San Bernardino, Palm Springs and Imperial County.
That portion of the 700 mile-long fault has not had an earthquake around that size in magnitude since about 1690...
But scientists are also especially worried about...the Hayward fault, which runs directly under cities in the Bay Area.
With these two areas of concern for seismologists, there are a number of potential scenarios that could play out in the earth’s crust – some of which could look a lot like the catastrophic, magnitude 7.8 earthquake in Turkey and Syria due to similarities in the way those faults are set up compared to California.
One such lesson is the potential for a “doublet” earthquake, or additional earthquakes triggered along nearby faults to one that has a “big one.”
The Hayward fault would be a candidate for a secondary earthquake that is dynamically set off if an earthquake, like a 7.4, were to hit in Southern California, she said, considering how much stress has already built up between the plates – mirroring what was seen in Turkey.

That’ll be me if a 7.5 hits.
Trump’s Fault.
I was 22 miles away from the epicenter of the Northridge quake - it felt and sounded like a freight train was running right outside my bedroom window.
Oh no, an informed rational post.
These drama queen posts watch too much sensationalist entertainment.
It’s California’s fault.
That’s a good idea. If the BIG one hits though, I imagine all pipe lines will break.
