One is not necessarily worse than the others. Each tornado, earthquake, volcanic eruption, and hurricane must be assessed individually. For all of these phenomena the magnitude of the effects can range from almost nothing to catastrophic. For example you can have an earthquake that does no more than knock a few pictures off of walls and a tornado that levels a whole town. Conversely, you can have an earthquake that devastates a whole region, killing thousands and a tornado that does no more than peel a few shingles.
However, if we look at just the worst few cases of each type of event, earthquakes appear to come out on top. There have been more earthquakes in recorded history with death tolls in the tens to hundreds of thousands than there have been of the others, especially if you include deaths from the tsunamis that some earthquakes generate.
No. Twister is just another word for a tornado.
There is no such things as "a Katrina hurricane." Hurricane Katrina was a particular hurricane that hit the Gulf Coast in 2005. Hurricane Katrina was worse than any tornado on record and deadlier and more destructive than any recorded snowstorm. Katrina was worse than most earthquakes, but not all. Hurricane Katrina killed about 1,800 people. Some earthquakes have had death tolls in the hundreds of thousands.
It can't. A hurricane can't become a tornado.
A hurricane is generally worse. Since they are much larger than tornadoes they can cause more damage and kill more people. e.g. A number of hurricanes have killed over 1,000 people, but only one known tornado has done the same. However, somewhat paradoxically, a tornado is more dangerous. This is because tornadoes are more violent than hurricanes, are harder to predict, and form much more quickly.
No, a hurricane is a huge storm hundreds of miles wide. A tornado is tiny by comparison.
The duration of Hurricane Ivan tornado outbreak is 48 hours.
The duration of Hurricane Georges tornado outbreak is 144 hours.
a tornado because of when it hit it it keeps going but a hurricane will stop at land
No, a hurricane is not a tornado over water. A tornado and a hurricane are quite different. A hurricane is a large-scale self-sustaining storm pressure system, typically hundreds of miles wide. A tornado is a small-scale vortex dependent on a parent thunderstorm rarely over a mile wide. A tornado on water is called a waterspout.
There is no conflict between a hurricane and a tornado. In fact, hurricanes often produce tornadoes. However, if you were to somehow pitch the force of a hurricane against the force of a tornado, the hurricane would "win" without being significantly affected. Although a tornado can have faster winds than a hurricane, hurricanes are much larger and have several orders of magnitude more energy than a tornado.
Zero. If you are killed in a hurricane, you are already dead, so you can't be killed by a tornado.
It depends. Hurricane ratings are based on measured wind speed, so a hurricane can become a category 5 but stay at sea, causing no damage. Tornado ratings are based on damage severity, so if a tornado is rated EF5, at least one well-built structure must have been completely obliterated. However, a hurricane that makes landfall at category 5 intensity can be expected to be much worse than most EF5 tornadoes.
