@catsalad When I lived where earthquakes were not unusual, small quakes of a short duration were no big deal to me. I had cats and dogs while living there, and I don't recall them reacting to small quakes. I haven't been in an area during a severe earthquake.

Living in an area where earthquakes are not the norm, even small quakes are disconcerting to me. Is my chair wiggling? What's going on? This shouldn't be happening here! Again, small quakes. My cats haven't noticeably reacted to them.
