Earthquake in Oakland

Last Friday there was a 4.2 earthquake around 4am. I felt the rumbling in SF, and it kept me awake for the rest of the morning. It’s not like I havn’t been in my fair share of earthquakes (Loma Prieta, Northridge, etc), but it’d been a while for me and I’d almost forgotten that SF is prime earthquake territory. Things to remember about being back in California.
