" a magnitude-6 earthquake or larger typically strikes every 10 years or so along the Sierra Nevada frontal fault system running from south of Yosemite National Park to north of Reno and Lake Tahoe. There were seven magnitude-6.5 or larger in the region from 1915 to 1954, but none since, he said. The last magnitude-6 was 22 years ago in the Carson Valley south of Carson City." http://www.sfgate.com/news/article/Sierra-s-eastern-front-long-overdue-for-large-7256632.php |

What happened prior to 1915, and maybe the earthquakes were abnormal?
I'd look at Mammoth Mtn which is active, for the quakes |

I check the Southern California Earthquake Data Center earthquake page for here, 118-39, almost every day. Not uncommon for there to be hundreds of micro quakes every week. Occasional quakes in the 3.5 to 4 range. I was hoping it meant that the tension was being released gradually and continuously.

whats fun is underground mining and all of a sudden the ground gets bad for mining, real roken up. Hard to maintain ground support, extra measures taken.
Then a geologist asks hows things going, oh real slow, bad ground. Well we thought so, this being were going through a fault. 
Oh ok no problem then. Mine through it and keep going, but knowing some shifting could make that impassable and trap someone on the far side. This one in particular was in n.nev. |

Was close to the epicenter for the Northridge quake, 1992 IIRC.
Don't think I've ever been so terrified, either before or since. There's not a damn thing you can do until the ground stops heaving One of the MANY things I do not miss about SoCal |

NYC actually has a few faults running through it. Drive up into Harlem and few realize that huge dip (at 125th st???) is the result of a fault line and one of the uptown bridges is designed to flex quite a bit in any direction. They're also in the due/past due realm time-wise...
