Best Answer

The Richter scale is for earthquakes, not tornadoes. Tornadoes are rated on the Enhanced Fujita scale. The largest tornado ever recorded was the 2.6 mile wide monster that hit near El Reno, Oklahoma in 2013. However, size does not necessarily correspond to a tornado's rating. Ratings are based on the severity of the damage a tornado inflicts. The El Reno tornado was officially rated EF3 but there are some indicators that it may have reached EF5 intensity, the highest rating possible.

Why are magmatic quakes severe?

Magmatic quakes (on the Richter scale, 6-10) are indeed severe quakes. The severity is caused by how large the movement of an earthquake is. If it is a timy move, it may be a 1-5 rank on a Richter scale. For the big movements, you never know how large scientists record it as. The maximum on a Richter scale is 10.


How big was the biggest earthquake?

What term defines the size of earthquake?

The Richter Scale is the established scale for earthquakes based on size and power.When you see that an earthquake is a magnitude 5.2 it means that it is a 5.2 on the Richter scale.For every increase of one on the Richter scale, an earthquake's power is magnified tenfold. So, a magnitude 4 is ten times stronger than a magnitude 3 earthquake.Anything over a magnitude 5 is a really big earthquake.
