Tsunamis

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.

Tsunamis in the open ocean are not dangerous at all; they aren't even noticeable. In deep ocean water a tsunamis is only a few feet to a few inches high and dozens of miles long. It is only when a tsunami reaches shallow water that it gains height.

Because width doesn't matter in a tsunami. The width is typically the length of the shore. It would be extremely difficult to classify a tsunami based upon height and width when the width is simply incomparable.

When a tsunami hits land, it can cause widespread flooding, destruction of buildings and infrastructure, and loss of life. The powerful force of the tsunami can carry debris and cause erosion of coastal areas, leaving behind a trail of devastation. It is important for people in coastal regions to evacuate to higher ground when tsunami warnings are issued to minimize the impact.

The 2011 tsunami in Japan primarily impacted the eastern coast of the country, especially the regions of Tohoku and Fukushima. The tsunami was triggered by a powerful undersea earthquake off the coast of Sendai, causing widespread devastation along the coastline.

Tsunamis are categorized by their size and potential impact based on their height and energy. The most commonly used scale is the moment magnitude scale (Mw) which measures the earthquake that generated the tsunami. The Tsunami Warning Centers also use terms like minor, moderate, and major to describe the potential impact of a tsunami.

It took several decades for the people of Krakatoa to fully recover from the devastation caused by the 1883 eruption and tsunami. The eruption resulted in the loss of thousands of lives and widespread destruction of property, leading to long-term economic and social impacts on the local population. The recovery process was slow and challenging, requiring significant rebuilding of infrastructure and communities.

Tsunamis are typically caused by underwater earthquakes, volcanic eruptions, or landslides that displace large volumes of water in the ocean. This displacement creates powerful waves that propagate outward to the shore, causing destructive flooding in coastal areas.

Tsunamis can violently inundate coastal areas, causing complete devastation of communities even miles inland. Tsunamis have been known to kill and injure thousands and leave many more homeless.

Tsunamis cause damage by two mechanisms: the smashing force of a wall of water travelling at high speed, and the destructive power of a large volume of water draining off the land and carrying all with it, even if the wave did not look large.

The fire occurred at the Cosmo Oil refinery in Chiba, after the earthquake and tsunami in 2011. The disaster severely damaged the refinery, leading to explosions and fires that burned for days.

The Japanese tsunami traveled up to 6 miles inland in some areas. If it were to hit Florida, the extent to which it would travel inland would depend on various factors such as the topography of the coast, coastal defenses, and the size of the tsunami.

No, the tsunami did not trigger a nuclear blast. The nuclear blast at Fukushima Daiichi Nuclear Power Plant in Japan was caused by a loss of cooling functionality due to the earthquake which occurred before the tsunami.

Cities along the Pacific coast of Japan were most affected by the tsunami that followed the 2011 Tōhoku earthquake. Some of the most severely impacted cities included Sendai, Ishinomaki, and Kamaishi.

The 2011 Japan tsunami affected around 20,000 people, leading to significant loss of lives, infrastructure damage, and displacement of residents in the affected areas. The aftermath of the disaster prompted large-scale humanitarian efforts and reconstruction projects to help those impacted.

In deep ocean water, the speed of a tsunami can exceed 500 mph but the wave height may be only a few feet. As the tsunami approaches shallow water and the sea floor rises, the speed decreases while the wave height increases significantly. This is why tsunamis can cause devastating flooding and destruction when they reach the coastline.

Well, some think that the end of the world is approaching. As I am Christian I believe this. It says in the Bible (Revelation) that natural disaters will come before the end of the world. But I guess it is up to you what you believe in. It could just be a coincidence. Hope this helps. :)

Massive earthquakes near oceans can generate tsunamis through the sudden displacement of large volumes of water. The earthquake's movement on the seabed creates a vertical shift in the overlying water column, triggering a series of powerful waves that can travel long distances across the ocean. These tsunamis can cause widespread destruction and flooding when they reach coastal areas.

There are tsunamis and there are tsunami trains.

A tsunami is generated by an underwater earthquake. A new tsunami has to wait for a new earthquake. It is not uncommon for any earthquake to be followed by one or more aftershocks within a matter of hours or days, so a new tsunami can result similarly. Since earthquake behavior is notoriously unpredictable, so is tsunami generation.

A single tsunami results in a series of waves with periods ranging from minutes to hours. This is called the tsunami "wave train".

There is more information in the related links.

A tsunami can reach depths of over 3,000 feet (about 1 kilometer) as it travels across the ocean. However, as it approaches the shoreline, the wave height increases and its depth decreases due to the shallow waters.

Yes, some people did leave Japan after the tsunami in 2011, especially those who were directly affected by the disaster and needed to relocate temporarily or permanently due to the destruction of their homes and communities. Many foreign nationals also left due to safety concerns and advisories issued by their governments.

No, tsunamis are not just one wave. They are a series of waves caused by underwater disturbances, such as earthquakes, landslides, or volcanic eruptions. These waves can be separated by periods of minutes to hours, with the first wave typically not being the largest.

First, the nuclear power plant CANNOT explode, and it didn't. What has apparently happened is that after the earthquake on March 11, 2011, the power plant was SCRAMMED, which means an emergency shutdown procedure. This prevents the nuclear fission reaction from continuing.

It is the heat of nuclear fission that boils the water into steam, and the steam turbines generate electricity. But even after the reactor is shut down, there is still LOTS of heat in the core, and you need electricity from some other source to power the pumps that circulate the cooling water. The nuclear power plant included a number of auxiliary diesel generators to generate enough electricity to cool the reactor core, but the diesel engines were disabled by the tsunami. The tsunami also destroyed all of the electrical power wires in the area, so with no power being generated by the reactor and no electricity available to run the coolant pumps, the reactors overheated.

We still aren't sure what has happened, but some of the uranium fuel rods appear to have been partially melted, and some radiation has been released into the environment. Some radioactive iodine-131 has been detected in the water supplies in Tokyo, but at very low levels. Iodine-131 has a half-life of only 8 days, so it is pretty radioactive, but it will all be gone in just a few months. However, radioactive iodine can cause thyroid problems, especially for infants, which is why the Japanese government has asked people not to drink the tap water. An "activated charcoal" water filter can remove even trace amounts of iodine from the water.

One of the problems with measuring radioactivity is that our detectors are SO GOOD these days that even very low - as in, "harmless" - levels of radioactivity can be detected. So far, nobody has been sickened by radiation, although several technicians have exceeded their "yearly safe allowances" for radioactive exposure.

If you are in the United States, you are certainly at a much greater risk of having an airplane crash on your house than you are from radiation for the leaking Fukushima Daiichi power plant.

In the deep ocean a tsunami wave travels at well over 800 kilometres per hour (500 mph). As the tsunami approaches the coast and the waters become shallow its velocity slows to below 80 kilometres per hour (50 mph) and it becomes taller.
