Earthquake

I had my first encounter with earthquake in the office earlier. It was surreal. I feel dizzy. Feels like vertigo. I keep seeing moving objects and it was as if I had problem with my vision. It was blur. It happened few times for less than 1 minute. When it happened I was sitting but suddenly I feel dizzy. At first I couldn’t register in my head what just happened. After few seconds, I realized that it is earthquake. Now I am worried bout my son at home. Is he okay??
