As it turns out, we did have an earthquake last night. Only 4.5 on the Richter scale, and it lasted for about a second. Actually, at the time I assumed it was the neighbour’s kids bouncing off or crashing into something. While the idea that it might have been an earthquake did occur to me at the time, it was only when I talked to someone at the Archives this morning who also felt it that I knew for certain. She lives nearly two hours away; my neighbour’s kids are simply not that loud.
