A girl who goes by the screen moniker "9Nania" uploaded a video to YouTube on March 9th predicting the earthquake to come 2 days later.  In her video, she warns that people in five major cities, which she lists, should get away from coastal and other high risk areas between March 11th and 15th.  She goes on to explain why using several online resources.  I found the video after waking in the early morning on the 11th to see the earthquake had happened an hour earlier.  I signed on YouTube to check for footage, and stumbled upon this video in the sidebar, which much to my surprise predicted the earthquake that just took place.  The video had only several hundred views at that time, but upon checking today I saw that it now has well over 100,000 views.  In her video, she continues to say "No one is listening to me and it is making me angry!" as she pleads for viewers to heed her warning.  I think it is safe to say that people will listen now.  You can visit her YouTube channel here:  http://www.youtube.com/user/9Nania
