Like all good immortals, I was awake when the quake hit. I live in Reno and was sitting in my office chair when it started slowly and gently wiggling back and forth. When I heard the roller shade chain hit the window, it confirmed that it was a quake and not my shaky balance. I think it lasted a good minute. Was definitely longer than 15 seconds for me. But again, Reno is far enough away that it was super mild. More like a 1.0 on the richter scale.
