"The next strong quake in the Whittier area was on the evening of June 15, 1967 centered East of Whittier. It had a magnitude of 4.1 and was felt as a rolling quake throughout much of the LA basin and parts of Orange County, knocking objects

...Regardless, this was my very first earthquake... I was in bed - it was about 9:15 p.m., when it hit it was LOUD! My bed started sliding on the tile floor... I could not get over the sharp jolting and shaking and that loud deep rumbling, at first it sounded like rocks being jostled around in a barrel.... and when the shaking stopped - you could still hear the rumbling gradually fade. The West Puente Valley really felt it, Obviously an event which left an impression on a 10year old kid...
