Surviving Earthquake

So...Monday there was an Earthquake at 22:50 (10;50 PM for you Westerners). I was just mae made aware of this fact. I was asked about it today one of the co-workers in the office. He told me that he was at home and felt it shake. When I told him that I didn't feel it, he seemed shocked. I am thankful that I wasn't aware of it, I think that I really would have freaked out, but I bet it would have made for an interesting story. I just got done reading that Japan has 20 % of the worlds Earthquakes. I didn't know this fact before traveling here. I pray that this is the only one for the next couple of weeks.
