I just went through my first earthquake, a breezy 4.5 (initial estimate), and it wasn’t so bad. I’ve never really heard a description of a “light” earthquake and certainly did not expect what happened. Hell, it took me until after the worst of it to realize what it might have been and even then I wasn’t sure.
At first, I had thought somebody had just dropped something outside onto a truck with a wooden flatbed, but the sound just kept going. It took me until after the sound had stopped and the “shaking” was still going to really put it together. It was really quite a nice little ride, more like a well-damped oscillator than a real shake.
