It was a rather small on only 3.7 on the Richter scale.
It was a short quake and thus not much damage if any occurred. Even if t was sustained at that level here probably would not be much damage. The LA basin needs a whole lot of these small quakes to relieve the stress, unfortunately we have not had them so the major fault lines keep building up energy to be released sooner or later
gives a nice rundown for the world
