Has anyone experienced an earthquake?

Grew up in California, and have experienced several. Hard to to pin your question down do to different variables. Sometimes it feels like the ground is rolling underneath you, then there are the ones that shake from side to side. Intensity varies considerably as does duration. You typically don't feel much or anything at a 4.0 or less on the Richter Scale. A 5.0 or greater, and it starts to get unnerving. Sometimes that only last a few seconds, while other times they can go on for close to a minute. Once it starts, find a safe place. They taught us to get into a doorway because they are structurally more sound. Getting underneath a desk or something similar is also good. I've been in two that caused actual damage. Loma Prieta in 1989. And the Nisqually quake in 2001. Both of those were pretty damn scary.
