I am no expert on earthquakes but Los Angeles has had a major quake about every 20 years. Following is a list of quakes in the Los Angeles region that was collected by Wikipedia. I have bolded those that were major shakers in Long Beach, Inglewood, West Los Angeles, and the San Fernando Valley.
My unscientific evaluation is that we are due for another major shaker NOW.
