A tsunami is the most DANGEROUS wave in the entire USA. It's 300 feet tall and 150 miles wide! While floods are almost as dangerous as tsunamis. Floods suck up everything in their way like tornadoes.
A slight correction...The "height" of a tsunami varies based on many variables, as does the "width". Basically, it's the amount of force that creates the wave, compounded by the wave eventually hitting the bottom of the sea and pumping up. The size, shape and contour of the beach plays a huge part in determining the height of the wave when it crests. In mid ocean, even near the source, the wave may only reach a height of 1ft, or may not be detectable at all.As to "width", it helps to envision this process by tossing a pebble in the middle of a pond. As the pressure wave propagates, it also dissipates in power, as more and more area becomes involved. The tsunami also dumps energy as it rubs on the bottom, so if your waveform is, say, 100ft, a long trip over water of especially 80ft (approx) or less removes energy from the wave as heat, derivative of friction.
A 300ft tall tsunami is very rare indeed, and depends entirely on land contour. A funnel-shaped bay that comes up quickly (or shelves) out of deep water is the most likely scenario for increased wave height. On the other hand, gradually shoaling water (think the US Carolinas as an example) come up gradually from the abyssal depths -- the added friction of crossing this area towards shore make the Carolinas nearly tsunami-proof.
Floods on the other hand, occur very very often. The cause can be localized rainfall, or runoff from mountainous regions, or it can be caused by local or distant heavy weather, creating a storm surge. Historically, floods have caused far greater loss of life and assets.

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 weather happens before a tsunami?
No weather in particular. Tsunamis are completely unrelated to the weather. Most tsunamis are triggered by earthquakes, which are not weather, but the triggering earthquake may be too far away to be felt.

What is the dangers of climbing Kilimanjaro?
in fact it is not floods it is tsunami and to say it its (su_nar_me) its when a earthquake happens under water and it then go's onto the beach and its a huge flood and kills almost everyone because of its fast movement then gos back into the sea and everything is destroyed.

Tornadoes are among the most dangerous forms of weather, but it is difficult to say objectively whether they are more dangerous than other events such as hurricanes.

What is more dangerous a tsunami or earthquake?
Earthquake itself is not dangerous if you know how to response. as long as you are on the right place, for example on an open place or inside seismic resistant buildings, etc you will be fine. Many people killed during earthquake because of panic and do wrong thing. tsunami triggered by underwater earthquake and off course more more more dangerous than earthquake. for example if there is no tsunami in sendai, miyagi, iwate area (march 11, 2011) the people killed will be not so significant. tsunami is the most dangerous natural disaster in the world.
