It was a couple of crucial choices in developing the EF scale – plus a rounding issue – that led to the apparent EF5 “drought,” according to the new study.
As the study notes: “Under the strictest application of the EF scale, to attain an EF5 rating from a single-family home being swept off its foundation, the home must technically be built above building code, which is a fundamental break from the F scale and will inherently reduce the number of EF5 DIs found in surveys.”
Key points, since there’s a lot of filler.
Thank you. So it is just cause americans have adopted yet another stupid measurment unit that doesn’t work well in reality.
