OceanStWx Posted April 28, 2011 Share Posted April 28, 2011 The Fujita scale was a wind scale. Fujita linked up the Beaufort scale with the Mach scale. The F-scale actually went to F12 (Mach 1) but F6 was considered inconeivable (nor would resulting damage be recognizable from F5). Since wind could not be directly measured it was inferred based on damage. Even Fujita, before his death, realized his scale was not relevent to cheaply built suburban housing, hence the EF scale. Thank you for clearing up my error, I knew that didn't sound right as I was typing it. The fact remains that the wind speeds are determined from damage, and the damage that occurred in 1974 is what is being compared to this event. In fact one could argue that poorly built structures 36 years ago might have been rated lower with the current EF scale not higher. I also apologize if this discussion no longer belongs in this thread, it seems to have taken quite the tailspin since I left work. Link to comment Share on other sites More sharing options...
