Earthquake in Hong Kong

This is one of the weirdest thing in my life. As I was working late in the office, I experienced my first earthquake in my life right in Causeway Bay, Hong Kong.

I felt the shake of the building 2 to 3 times. I thought it was someone moving some huge furniture but later my friend SMS me about it. And now I saw the news on TV. It’s for real.

The earthquake is of level 3.5

So is my home safe? Is my office safe? When will it happen again? And will it escalate to much higher magnitude?
