I live in the San Fernando Valley... so basically being raised to feel any little jolt after the Northridge Earthquake, I felt this one. It wasn't much, but at around 12:18, my dad walked in, and I felt it as my chair started to gently move along my plastic floor mat with my butt sitting in it. I got up, started walking toward my door frame just in case, and it ended. I went over to ask if anybody else felt it, nobody did. My brother tried to call shens and said it was cause my little sister was running around. He looked it up and the USGS website, and found it... n00b.
