Mercalli scale! I had this same question on my homework last night.
Mercalli scale
Richter scale
Yes. Wind speeds can be estimated from damage and sometimes measure using Doppler radar, which can yield a rating on the Enhanced Fujita scale. The length and width of a tornado's damage path can also be measured, though this has no bearing on the rating.
I have no idea but this website should know. try to find the answer to this answer
No tornado has ever been stronger than F5. Fujita scale ratings are based on damage and F5 damage damage is total destruction. This makes it impossible to assign a higher rating.
There is no "category" for winds in a tornado. Tornadoes are measured by the Enhanced Fujita Scale, which simply is a rating based on the amount of damage done. It ranges from weakest EF-0, to strongest EF-5....250mph winds are "capable" of producing EF-5 damage, should it move over certain sturdy structures. However, a tornado over an open field with 250mph will not get an EF-5 rating because it has no sturdy structures for it to damage. Tornadoes are rated after the fact based on the amount of damage done. So while a 250mph wind "could" produce EF-5 damage, it's got to move over the right structures for that damage to be realized and the tornado given that rating.

Technically, you can't tell damage from the Richter Scale, because the Richter Scale rating of an earthquake stays the same no mater how far out you go from the epicenter. The scale that measures the damage of an earthquake (meaning the scale rating gets lower the further you go from the epicenter) is called the Mercalli Scale. The Mercalli Scale goes from II to XII (2 to 12) and the rating on the Mercalli Scale in which damage starts to occur is about 6. However, if you are going by the Richter Scale, damage at the epicenter would start at about 5.0
actually, the highest rating was an earthquake in Chili, coming in on a 9.5
The rating was 9.0, which is almost complete destruction.
8.9 on the Richter scale.
The rating system used to estimate the total energy released by an earthquake is the Moment Magnitude Scale.
8.9 on the Richter scale
It is the Richter Magnitude Scale.
In Valdivia, Chile in 1960, with a magnitude of 9.5
