I've been back and forth to California so many times that it is well over a year (perhaps closer to two) that I have spent there and not once did I see an earthquake. If there were tremors, they would be so minor to not be noticed with whatever else I was doing.
That said, I have recognized 3 earthquakes in Ontario of all places. Two in Toronto, and one in eastern Ontario. Luckily none of them caused any damage near me,
- The first was way back in 1980, and centered around Cincinnati (magnitude 5.2). I was alone in my high-rise apartment on a quiet Sunday afternoon reading, and I could hear the doors in the building start to rattle which continued for a half minute or so. I didn't really connect it to an earthquake until I was listening to the news later that evening and the times matched.
- The second was in 2010, and I was home working on the computer and could feel it. I immediately started combing the Internet and found it was centered in Quebec (magnitude 5.0).
- The latest was in 2013, I was outside digging a foundation for a shed. This was harder to recognize, I began wondering if I had over exerted myself and the trembling was coming from my legs. I checked out the news later that evening, and yes another earthquake centered in Quebec. There were actually two recorded at 10 minutes apart (magnitude 5.2, and 4.1), but I only felt one (I assume the first).
