Later reports suggest a lower death toll than earlier suggested, though still significant and just as tragic for those affected.
This is a major tragedy and the casualties it would appear are being downplayed especially when you consider whole neighborhoods are left with just with the outline of the concrete foundations of hundreds of individual homes. And this is just one neighborhood as the area of destruction of 30-40 square miles. Casualties will most likely be in the many hundreds to thousands.
It seems to me that the real problem is from reporters and "talking heads" speculating about the death toll and then presenting their speculations as fact.
The authorities appear to be basing their numbers on actual recovered remains. Many are missing, unaccounted for and some are probably trapped. Some percentage of those will add to the death toll, but how many must be determined one by one as the search continues. There is a lot of territory and rubble to be searched.
