No progress in lifting debris to find survivors

Despite the availability of cranes on site and the very real possibility of survivors trapped in the ruins, almost nothing of the debris was removed between September 12 and 13th when these pictures were taken.  Under the debris are the ruins of at least four floors of offices above ground level and one below.
