Earthquake

Another earthquake has hit Iran.

Recently a huge quake in the ancient city of Bam killed more than 25000 people, and destroyed the city.

Something that draws my attention is that, as BBC reports:

"The geophysical institute at Tehran University said the magnitude of the quake was 5.5, while the Strasbourg seismic observatory put it at 6.1 and the American Geological Survey said it was 6.2"

How is it that the Tehran University geophysical institute is reporting something while they have senced otherwise from France or US?! which observation is flawed?! are the scientists in Tehran using old instruments or is there any policy to report the earthquake power less than what it has been in order to avoid people from panic! or what?
