First off, it's important to be clear about the fact that tsunamis themselves can not generally be mitigated or reduced in intensity. Ocean Data Aquisition System (ODAS) buoys comprise part of a tsunami early warning system. The earlier the tsunamis are detected, the earlier that the population and infrastructure on threatened Coastlines can be warned, hopefully lessening damage and loss of life. Tsunamis are formed as the result of seismic events which transfer energy to the surrounding sea. Thus, the earliest means of detecting them is through seismic (i.e. earthquake) measurement. A particular seismic event is a good predictor of an associated tsunami, depending on its intensity and the location of its epicenter. ODAS buoys supplement this by measuring characteristics of the sea waves which are generated. An ODAS buoy can measure the wave height (3d position at any given time), and also the period between consecutive waves. This provides a good indication of both the destructive potential of a particular wave train, and its propagation time (i.e. how long the waves will take to reach land). This information is invaluable if it can provide advance notice to a threatened area. Other ODAS capabilities may include acoustic measurement (direct observation of seismic activity), sea salinity, temperature, wind direction and velocity, current speed and direction, etc., for weather monitoring and prediction. At sea, a seismic event which generates a tsunami may not even be noticeable from a seaborne observer, since the resultant wavelength is generally very long. Imagine floating in a small boat while a 20 meter high wave passes beneath you - if the wavelength is short, such a wave would obviously be devastating. If, however, a wave this high took a full minute to pass beneath you, your change in elevation would occur so slowly that it may not even be noticed. Long wavelength, high energy waves like this are typical of tsunamis. Thus, the ODAS buoys provide a means of detecting and describing them well out at sea - hopefully in sufficient time to prepare for their landfall.

What instrument is used to detect tsunami?
A tsunami detection buoy is one of the primary instruments used to detect tsunamis. These buoys are equipped with sensors that can detect changes in water pressure caused by a tsunami wave passing overhead. The data collected by these buoys is then transmitted to monitoring stations to provide early warnings.
When was tsunami warning system first used?
The first tsunami warning system was established in the Pacific Ocean in 1948, following the destructive tsunami that occurred in the region in 1946. The system was put in place to help detect and warn about potential tsunamis to minimize their impact on coastal communities.
What is a category 5 tsunami?
There is no such thing as a category 5 tsunami. Category 5 is a rating on the Saffir-Simpson scale, which measures hurricane intensity. Category 5 is the highest rating, indicating a storm with sustained wind exceeding 156 mph. Tsunamis are a completely different phenomenon and have no rating system.
The common name for tsunami?
A tsunami is also known as a 'tidal wave', which used to be the more common term. These days, 'tsunami' seems to be the more commonly used name, at least in the Pacific rim countries where English or Japanese is spoken.
What is the instrument that measures tsunami?
A tsunami buoy or tide gauge is commonly used to measure tsunamis. These instruments detect changes in water pressure and height to monitor tsunami activity. Additionally, seismic instruments can also be used to detect the earthquakes that trigger tsunamis.

What is a homophone for boy?
Buoy is a homophone for boy. A buoy is a floating object used to mark a location in a body of water.
What is an anchor buoy?
An anchor buoy is a small buoy attached to an anchor by a light line and used to indicate the position of an anchor.
What is used to fight against tsunami?
You can't fight against tsunami's. You can only flee. That's why countries with risk of tsunami's have invested in a tsunami-warning system. But a well-built house always helps in comperison with cheap, slum-like buildings.
A floating marker used as a warning or a guide for ships?
The word is buoy.
What does a red and green buoy mark?
A red and green buoy typically marks a channel or navigational route in water. The red buoy, which is usually on the right side when entering a harbor or river from the sea, indicates the starboard side, while the green buoy, on the left, indicates the port side. Together, they help guide vessels safely through navigable waters, ensuring they stay within designated channels. This system is part of the IALA buoyage system used in many countries.
What term is used to describe the anchor buoy when it is floating on the surface above the anchor?
The term used to describe the anchor buoy when it is floating on the surface above the anchor is "marker buoy" or simply "buoy." This device is used to indicate the location of the anchor underwater, making it easier for boaters to retrieve the anchor or to mark a specific spot in the water.
What is a Yellow buoy used for?
Achoragae area
What is does a number 4 buoy mean?
A number 4 buoy typically indicates a lateral marker used in maritime navigation, signifying the left side of a channel when entering from the sea. It is part of the IALA (International Association of Lighthouse Authorities) buoyage system, specifically following the "IALA A" system, which is used in most parts of the world. The buoy is usually colored red or has a red band and may also feature a specific shape, such as a can or cylinder, to help mariners identify it easily.
When returning to homeport from Seaward and you see a red buoy what should you respond?
When returning to homeport and you see a red buoy, you should respond by keeping the buoy on your starboard (right) side as you navigate. Red buoys indicate the right side of a channel when returning from sea, following the IALA System A used in the U.S. and many other regions. Always ensure to remain aware of your surroundings and other vessels as you approach the buoy.
What is bifurcation buoy?
a horizontally marked red and black buoy used to mark the division of sea lanes when moving inward from the sea.
