Who is Enhanced Fujita Scale?

The Enhanced Fujita Scale is a way to tell how strong a tornado is by looking at what it can do.

Imagine you're playing with building blocks, and a big wind comes in and knocks them all down, that’s like a weak tornado. But if the wind was so strong it pulled your house off its foundation or turned cars into flying toys, that's a really strong tornado.

The scale goes from EF0 to EF5, just like how you count from 1 to 5.

• An EF0 is like a light breeze, maybe it flicks your hair but doesn't do much else.
• An EF5 is like the wind in a superhero movie, it can tear apart whole buildings and send things flying like they're in a giant pinball machine.

Scientists look at how bad the damage is to guess the tornado's strength. They check broken windows, flipped cars, and even how far trees are thrown, just like you might count how many blocks you knocked down when you play.
