They all have different causes.
Hurricane formation starts when an area of low pressure, showers and thunderstorms called a tropical disturbance moves out over warm ocean water. The warm, humid air from that water fuel the thunderstorms, causing more to develop. The rising air currents of the thunderstorms lower the pressure even more, which causes the system to draw in more air to fuel the storms. As the pressure drop the wind speed increases. Through this cycle the disturbance grow stronger. As the wind speed increases the Coriolis effect, a consequence of Earth's spin, causes the disturbance to start rotating. The rotation causes the system to become more organized, which lets it draw in air more efficiently. When the rotation becomes well-defined the system is upgraded to a tropical depression. When sustained winds reach 39 miles per hour the depression is called a tropical storm and is given a name. When winds reach 74 miles per hour the system is declared to be a hurricane.
To form tornadoes, first we need thunderstorms. The thunderstorms that produce tornadoes most often, though not always, develop along a cold front or dry line, where cool or dry air pushes into warm, moist, unstable air. The next step needed is wind shear, or difference in wind speed and direction at different altitudes. The wind shear affects the storms in two ways. First, it separates the updraft and downdraft sections, preventing the cold downdraft from choking off the updraft, an event that kills most thunderstorms. With this obstacle out of the way the storms can become stronger and last longer than usual. Second, the wind shear sets the thunderstorms rotating. If this rotation can tighten, intensify, and reach the ground then a tornado is formed.
Tsunamis are usually triggered in one of two ways: an underwater earthquake or a landslide. Earthquake-triggered tsunamis occur at places called subduction zones, where one of Earth's tectonic plates slowly slides underneath another. As the plates move, they snag and then build up tension over many years. When that tension is released an earthquake occurs. At subduction zones the release can also cause vertical shifts int he sea floor, which displaces huge amounts of water and generates tsunami waves. A landslide that either occurs underwater or slides into the water can also trigger a tsunami in a similar way.
What else can I help you with?
What is the most dangerous hurricane tornado tsunami or earthquake?
The one that you are nearest to. All are dangerous depending on their location.
What is the analogy of Tsunami is to water as cyclone is to?
Tornado. Both are intense weather phenomena characterized by powerful swirling winds, but a tornado occurs on land while a cyclone (hurricane or typhoon) occurs over water.
Is a tsunami just a water tornado?
No. A tsunami and a tornado are two completely different things. A tsunami is a large wave or series of waves usually triggered by an underwater earthquake or landslide. A tornado is a violent vortex of air that forms during a thunderstorm. A tornado that forms on water is called a waterspout.
Is a hurricane a water tornado?
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.
What are the odds of getting killed in a hurricane then a tornado?
Zero. If you are killed in a hurricane, you are already dead, so you can't be killed by a tornado.

Tornado, Hurricane, Twister, Thunder, Cyclone, Tsunami, Typhoon
What is storm Leones special moves?
storm leones special moves are hurricane crunch, tornado lion claw, and tsunami twister
Who will win tornado or tsunami?
Niether. In the unlikely event that a tornado and a tsunami met, the tornado would go right over the tsunami and neither would be significantly affected.
Does a hurricane or tornado or blizard or freezng rain which one causes the most flooding near an ocean.?
A hurricane causes coastal flooding. None of the other are directly related to flooding at all.
Is a tsunami a hurricane in the water?
No. A hurricane on water is simply a hurricane. Tsunami is a large wave triggered by an underwater disturbance such as an earthquake. A hurricane is a type of storm.
