A 7.2 earthquake can be significant :!:
*can* indeed. Also I suppose they're looking at the quake as a whole - ie, fearing that Los Angeles is about to be hit by the 'big one'.
Interesting that places like the BBC only mention Los Angeles briefly:

I do want to be in an area that has a minor earthquake at some time in my life, just to feel what it is like. Of course don't want to be under a freeway or above the fault line at the time! Have missed two in recent years by only a few weeks.
