Earthquake ~~!!!

I experienced a small earthquake (Scale 6.6) tonight, my first time. I was sitting on my bed, and I felt the whole buiding shaked violantly, and might even collapse owing to the poor construction quality. For a few seconds, I felt my life was at risk. Different stuff inside my messy room dropped onto the floor. Now it is time to fear instead of rejoice living on the 14th floor. It seems that none of my colleagues finds it a big deal, except they were awaken by the earthquake in mid-night. Neither do they know the emergency procedures. The only commonly agreed action is: open the door, so there is a way out in case the ceiling falls down.
