“Since 1999, no tornado has been given a F5 rating. This could be that the damage in Oklahoma City has set an unmatched standard for F5 damage, or that the application of more stringent assessment of structures has led to lower damage ratings. Figure 5a and 5b show the difference in FScale ratings between the years 1990-1999 and 2000-2005.”
