It is difficult to say what tornado was the most violent because once they reach a certain level it is difficult to tell the difference.Candidates for this title, though, include:
The Tri-State tornado of March 18, 1925 (tore across parts of Missouri, Illinois, and Indiana)
The Xenia, Ohio tornado of April 3, 1974
The Jarrell, Texas tornado o May 27, 1997
The Moore, Oklahoma tornado of May 3, 1999 (based on a rare wind measurement).
The most violent tornado and only F5 tornado recorded in the month of August struck Plainfield, Illinois, southwest of Chicago, on August 28, 1990.
Tornadoes are the most violent storms on Earth. As such a tornado will usually be the most violent part of its parent storm.

Tornadoes have almost no effect on landforms. In extreme cases an exceptionally violent tornado may strip away a foot or two of soil, but that is the most you will see happen.
A tornado anywhere is a violent event. If you mean by the technical definition of a violent tornado, one rated EF4 or EF5, such tornadoes do occur fairly regularly in Tornado Alley, but make up a very small minority of the tornadoes that occur there. As with most places, most of the tornadoes in Tornado Alley are rated EF0 or EF1.
A supercell is the kind of thunderstorm most likely to produce a tornado.
Most tornadoes form in violent thunderstorms called supercells.
No. Cyclones and tornadoes are completely different phenomena.
It depends. A tornado is defined as a "violently rotating column of air" and most people would consider any tornado a violent event. However, in discussing tornado strength, a violent tornado is one of EF4 or EF5 intensity. Less than 1% of tornadoes recieve such ratings.
Either the funnel cloud or the violent, rotating winds associated with it must reach the ground in order to be classified as a tornado.
The Plainfield Tornado didn't live for long, but it was violent enough that it killed 29 people and injured 353, and caused over $140 million dollars worth of damage. Its rating of F5 means that it was in the most violent category of tornado. Tornadoes rated F4 and F5 are classified as violent. A weak tornado has a rating of F0 or F1.
This most closely describes a tornado, though a tornado technically is not a cyclone.
