That title goes to the Super Outbreak of April 3-4 1974, with a total of 30 violent tornadoes. Officially, 7 tornadoes were rated F5 and 23 rated F4.
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.
The 1974 outbreak was not a single tornado but series of 148 tornadoes. It is famous because it was the most intense as well as one of the deadliest and until recently the biggest of all tornado outbreaks on record.
Tornadoes are the most violent storms on Earth. As such a tornado will usually be the most violent part of its parent storm.
It is difficult to determine, as until the 1990s we did not have an accurate count of weak tornadoes. The largest number of recorded weak tornadoes tornadoes in an outbreak would probably go to the Super Outbreak of April 25-28, 2011 with 264 tornadoes rated as weak. This outbreak also holds the record for most tornadoes overall at 349.
A tornado is a violent weather event the most violent in fact. Tornadoes are produce by thunderstorms and are, in simple terms, extremely violent rotating windstorms.
That depends on which tornado record you are referring to. Here are a few records:Largest tornado: the El Reno, Oklahoma tornado of May 31, 2013 (2.6 miles wide)Longest lived tornado: the Tri-State tornado of March 18, 1925 (3 hours, 29 minutes)Longest damage path: the Tri-State tornado of March 18, 1925 (219 miles)Costliest tornado: the Joplin, Missouri tornado of May 22, 2011 ($2.8 billion)Deadliest tornado: The Daulatpur-Saturia, Bangladesh tornado of April 26, 1989 (1,300 dead)Fastest winds: the Oklahoma City tornado of May 3, 1999 (302 mph)Largest tornado outbreak: the Super Outbreak April 25-28, 2011 (351 tornadoes)Costliest tornado outbreak: the Super Outbreak April 25-28, 2011 (~ $5 billion)Most tornadoes in 24 hours: April 27, 2011 (208 tornadoes)Most violent tornadoes in an outbreak: the Super Outbreak of April 3-4, 1974 (24 F4, 6 F5)
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.
No. Cyclones and tornadoes are completely different phenomena.
There are different ways of assessing this as "worst" is subjective.The deadliest outbreak in U.S. history was the on which produced the Tri-State tornado of March 18, 1925. In all, this outbreak killed 747 people, including 695 from a single tornado. There are record of 9 tornadoes in this outbreak, but it is likely that many others were not reported.The most intense outbreak on record in terms of the number of violent tornadoes was the Super Outbreak of April 3-4, 1974.

It is one of only two outbreaks to have produced more than two F5 or EF5 tornadoes. In all, 319 people were killed. This outbreak also held the title of most tornadoes within 24 hours until 2011.The costliest outbreak in terms of property damage was the Super Outbreak of April 25-28, 2011. It was also the largest tornado outbreak ever recorded. The cost of damage amounted to about $5 billion. Most of the damage was on April 27. In all the outbreak produced 351 tornadoes, of which 207 were on April 27, the current holder for the 24-hour record. Of these tornadoes, 11 were rated EF4 and 4 were rated EF5.

There have been two events that have been called a "Super Outbreak." For Decades Super Outbreak referred only to the devastating outbreak of April 3-4, 1974. This outbreak was, at the time, the largest tornado outbreak ever recorded, producing 148 tornadoes in 18 hours. Tornadoes occurred across a large area stretching from Ontario to Alabama. To this day it stands as the most violent outbreak on record with 23 tornadoes rated F4 and 7 Rated F5. Several tornadoes killed 20 or more people each in area of Ohio, Kentucky, and Alabama. The deadliest tornado of this outbreak hit Xenia, Ohio, killing 32 people. Major killer tornadoes also hit Brandenburg, Kentucky (31 dead); Tanner, Alabama (28 dead); and Guin, Alabama (28 dead). In all the tornadoes of this outbreak killed 319 people. More recent was the Super Outbreak of April 25-28, 2011. It stands as the largest tornado outbreak ever recorded, having produced 351 tornadoes in just over 3 days. It also holds the record for most tornadoes in 24 hours, with 208 tornadoes touching down on April 27, the worst day of the outbreak. It is also one of the most violent outbreaks on record, with 11 tornadoes rated EF4 and 4 rated EF5, all on April 27. This marks only the second time in history that more than two F5 or EF5 tornadoes struck on the same day. While the range of the outbreak was similar to that of the 1974 Super Outbreak, all of the violent tornadoes were limited to the southern states, with Alabama suffering the worst damage. This outbreak distinguishes itself from the 1974 event with two tornadoes with extremely high death tolls. A long-track EF5 tornado killed 72 people across numerous towns in northern, Alabama, the deadliest single tornado in state history. Another tornado, rated EF4 killed 64 people in Tuscaloosa and Birmingham in central Alabama, the state's second deadliest tornado. Other major killer tornadoes hit Rainsville, Alabama (25 dead); Smithville, Mississippi (23 dead); Ohatchee, Alabama (22 dead); and Ringgold, Georgia (20 dead). In all the tornadoes of this outbreak killed 324 people.
