If that was a small earthquake, I never want to be in a big one!
For just a few seconds this morning (maybe 4) the building shook in a way buildings shouldn't shake accompanied by a low rumbling sound. It actually felt like the building lent way from me while I sat at my desk but I would guess that's just perspective playing tricks. I did get up and check the back to see something hadn't driven or fallen onto it (tree perhaps?) but all seemed normal so I got back to work wondering if that was an earthquake.
