How strong is a tsunami from a hurricane?
Hurricanes do not cause tsunamis. The coastal flooding from a hurricane is called the storm surge. This storm surge varies in severity depending on the strength of the storm and the shape of the coastline. The impact may range from minor flooding, to the complete destruction of coastal communities.
What is the word for the defintion a very large wave caused by high winds over a large area of ocean?
The term is "tsunami." Tsunamis are typically caused by underwater earthquakes, volcanic eruptions, or landslides, rather than high winds over the ocean.
What is the name of a very large wave caused by high winds over a large area of ocean?
surge Storm surge waves.
What was the estimated storm surge for hurricane Katrina?
The average storm surge for Hurricane Katrina was about 22.8 ft. setting a new U.S. record for highest storm surge. The water came crashing through hotels, banks, and even 150 foot skyscrapers which is about 17% of the building! WOW! So, as you can see a storm surge can be a very serious thing!
Is a hurricane a tsunami?
No. Hurricanes produce large waves, but these are not tsunamis. Tsunamis are the result of the movement of the ground underwater, such as with and earthquake, landslide, or volcanic eruption and have completely different dynamics from storm driven waves.
What is storm surge and what affect does it have on the coastline?
A storm surge is slight rise in the ocean associated with a tropical cyclone, which manifests itself as a large rise in water level at the shore as the storm hits. This can vary from a few feet to 20 feet or more. It is a consequence of both the low pressure at the center of the storm raising the ocean surface as well as the wind pushing the water in the direction the storm is moving. This surge is not to be taken lightly as most deaths occur because of this surge. It can inundate seasides and entire towns and sadly, the unwary are usually its victims.The storm surge is a bulge of water created by a hurricane. The pressure in a hurricane is very low and as a result the water level in a hurricane rises. When a hurricane hits land the storm surge comes ashore as well, flooding coastal areas. The storm surge is responsible for 90% of hurricane deaths.Surge. When there is a storm at sea, it will cause the waves at the shore to be higher than normal.
What factors make a storm surge weaker or stronger?
Storm surge is generally made stronger by several factors:Stronger winds.Larger area covered by strong winds.Longer duration at a higher intensity.Lower barometric pressure, though this is a smaller contributor.High tide, though not a component of storm surge, can add to it in what is called a storm tide.The opposites of these will lead to a small storm surge.Originally storm surge was correlated with wind speed alone, but this was discarded.Examples:In 2004 Hurricane Charley struck Florida as a strong category 4 hurricane. This would normally bring a very large storm surge, but the storm was small and had only recently intensified from a category 2.In 2005 Hurricane Katrina struck the Gulf Coast as a category 3, but due to the storm's enormous size and having recently weakened from a category 5, it had an enormous storm surge.
How does The category 5 hurricanes are the most destructive?
A category 5 is the strongest hurricane. Such a storm has the strongest winds and usually produces a very high storm surge.
What is the different between a cyclone typhoon tsunami?
A tsunami is a wave resultant from a storm. However, cyclones and typhoons are very similar with cyclones occurring in the western hemisphere and typhoons in the eastern. The major difference is that the eye of a cyclone is round, whereas the eye of a typhoon is slanted.

What is the most dangerous effect on a hurricane?
The most devastating after-effect of a hurricane is coastal and inland flooding related to storm surge. A storm surge is water that's pushed ashore as a result of hurricane winds. The storm creates winds and weather conditions of its own. This, combined with regular normal tides in the area, create a "hurricane storm tide," also known as a storm surge. Water from this tide can result in an increase in the water level by 15 to 20 feet - or more. If a storm surge comes ashore in an area that is flat or not very high above sea level, the results can be horrific, as seen in the United States most recently in Hurricane Katrina. This storm produced the highest storm surge in the U.S. - more than 28 feet in some areas. Predicting storm surge is a significant part of predicting where a hurricane will hit, as this is a factor in knowing what areas of the communinity must evacuate.
What is the difference between a strait and an Tsunami?
A Tsunami and a strait are very different things. A strait is a narrow string of water, while a Tsunami is a massive wave.
