The fault that these are occurring on is not big enough to produce anything near a major quake.
There is a fault about 1 mile from my home that is capable of producing an 8.0. I think the fault in La Habra is only capable of producing something around a 6.0 (which is 100 times stronger than the one last night, but not likely to cause any kind of major damage in Southern California).
How long have you lived in California?
Since 1971, Northern CA for all but six months of that time.
The San Andreas is the one we “fear”
I wasnt aware that there were that many faults in SoCal.

The Bay Area in Northern California “boasts” the San Andreas fault and the hayward fault. As far as I know there arent any others that have moved since ive been here
