was designed. the same thing happened again tonight. my understanding is the alerts it did not go out in l.a. a magnitude that was estimated from the warning system was 6.2. the initial magnitude estimate, it s below that threshold. the system is not perfect. what was experienced here in the pasadena l.a. area, these are not damaging ground motions. in ridgecrest, that is damaging ground shaking. they are feeling it. reporter: is there a chance for an even larger went and as a doctor jones said, there is a 5% chance this could be followed by an even larger quak quake. the number of 5% is usually
strongly. even in the l.a. area, we ll have reports of feeling it. any take aways from this quak quake? here is the definition of the change in a news cycle. you re still asking us what was the magnitude. we can give an accurate magnitude very quickly. it not been an hour since the earthquake. one comment i would make, we had a lot of after shocks. those in general are not being felt down here in the l.a. basin, up in the owens valley area, i m sure they are feeling a lot of after shocks. i haven t had a chance to keep track, but we ve had dozens, i think about three at this.. we will continue to have a lot of after shocks. this area is also characterist ically have low frequency.
