Earth Quakin

So I again live where earthquakes are a regular occurrence. The elevators have special sensors that detect quakes and take you to the nearest floor and let you out when they occur. We had one here while I was sitting at the computer. It was sharp and quick. I was not even sure I had felt what I thought it was. I had to confirm with other people that I had indeed felt a quake. The good news is that I remember all the stuff we were taught in school (here in Japan) about quakes and what you need to do to be safe. I wonder what other geological/weather phenomenons I will experience while living here?
