Earthquake in Tehran

It is 17:20 Friday
A few minutes ago Tehran was shocked by earthquake. It was unbelievably feared people. I am in my office to work on an article. Suddenly everything was shaking. It took long about 15 seconds. But nothing destroyed. I am looking out of the window. People have come out with their children and are disturbed. A few months ago Bam city shocked once at midnight and then a few hours later the tragedy happened and more than 26000 died. Perhaps it was a message. What do we can? What? I am looking to the old men and women who are in the street…..insecure country in all its aspects. Natural insecure, social insecure, political insecure and so on……
