Hah! 3.7, that's nothing. We' must have had four or five 5.4 plus earthquakes since Easter Sunday.
All fun aside, yeah earthquakes aren't really fun. They just kinda come and you cross your fingers it's not going to be a huge one. Then you call everybody in the immediate area and ask "did you feel that?"
It has not been confirmed by anyone that it was the man's son, and it's insane to think that you could tell from those two pictures. The father laughed about the question, saying that his son would have been recognized by everyone there.
