Tsunamis
Tsunami are huge waves that form in large bodies of water (e.g., oceans, seas, large lakes), that are caused by abrupt vertical displacement of a huge column of water. The displacement can be caused by naturally occurring events such as earthquakes, landslides, volcano eruptions, etc., and even sometimes from underwater explosions. These can become natural disasters devastating to the people and properties along the shore lines where they ultimately appear, sometimes in waves as big as hundreds of feet high or higher.

Light is an electromagnetic radiation. Our eyes are sensitive, the E/M radiation at the light wavelength. Hence we see light.
The E/M radiation adjacent to light are Infra-red(IR) and Ultra-violet(UV), which we do not see.
What Philippines islands more prone for Tsunamis?
The Philippines islands that are more prone to tsunamis are those located along the eastern side of the country, facing the Pacific Ocean. This includes islands such as Samar, Leyte, and Mindanao. Areas near tectonic plate boundaries, such as the Philippine Trench and the Manila Trench, are also at higher risk for tsunamis in the Philippines.
Why did the Pacific Tsunami Warning Center cancel an alert for Hawaii on February 27 2010?
The Pacific Tsunami Warning Center canceled an alert for
Hawaii on Saturday, after waves caused erratic surges in the
sea but did not appear to cause significant property damage.
Gerard Fryer, a geophysicist at the center, told The
Associated Press that the state had "dodged a bullet" after a
major earthquake in Chile a half-day earlier had caused
tsunami warnings to be issued for most of the Pacific basin.
Is there really a tsunami in Australia today?
I'm not aware of any reports of a tsunami in Australia today. It's always a good idea to check with official sources like government websites or weather agencies for the most reliable and up-to-date information on natural disasters.
Why does TSUNAMI start with the letter T?
The word "Tsunami" comes from the Japanese words "tsu" (harbor) and "nami" (wave), as tsunamis are typically generated by undersea earthquakes or volcanic eruptions that cause powerful ocean waves. The "T" in tsunami reflects its origin and pronunciation in the Japanese language.
How bad was the damage from the tsunami that hit Hawaii?
7.0
Really a tsunami did not hit Hawaii they just had abnormally high waves hit the shores. The highest reported was 6 feet. And I don't know if they had much of any damage.
Why are lots of earthquakes and tsunamis happening?
Earthquakes and tsunamis occur due to movement of the Earth's tectonic plates. When these plates shift or collide, it can result in seismic activity such as earthquakes. Tsunamis, on the other hand, are often caused by underwater earthquakes or volcanic eruptions that displace a large volume of water.
How many tsunami warning systems are there currently in the world?
There are several tsunami warning systems in the world, managed by organizations such as the Pacific Tsunami Warning Center (PTWC), the National Oceanic and Atmospheric Administration (NOAA), and the Japan Meteorological Agency (JMA). These systems provide alerts and forecasts to coastal communities in the event of a tsunami threat.
Is it possible to get a tsunami here in california?
It really depends on the magnitude of the earthquake (which causes tsunamis in the first place). But to answer your question, yes it's likely that it will reach California, especially if you're in areas such as San Francisco, Long Beach, San Diego, Santa Monica, or anywhere else with beaches nearby.
How high were the waves during the tsunami in Banda Aceh?
During the 2004 Indian Ocean tsunami in Banda Aceh, Indonesia, waves reached heights of over 30 meters (100 feet) in some areas. These massive waves caused widespread devastation and loss of life in the region.
What happens to a submarine ship during a tsunami?
Though modern submarines are affected by surface weather and tidal forces if close enough to the surface (I've experienced 12 - 15 degree rolls at 400' as a hurricane passed over us, and other submariners have reported up to 40-50 degree rolls in Category 4/5 hurricanes, even at test depth), tsunamis are only deadly to submarines as they approach shallower areas of land, which aren't really deep enough for submerged operations.
The only real threat would be a tsunami hitting a coastal area without warning if the boat was underway surfaced in shallow water (e.g., entering or exiting a harbor area), or if it was moored at a pier when one struck. In such a case, it would be subjected to tidal stresses similar to a hurricane storm surge or worse, depending on the strength of the wave. Hurricanes give enough warning that oceangoing vessels can emergency sortie (get underway) quickly to clear port before it hits, as all ships and submarines are designed to handle severe weather at sea. In port however, it's a much different story, as the tidal forces can literally bring a boat out of the water if it isn't prepared properly.
In one such instance I remember, as Tropical Storm Dean headed the East Coast in 1983, we had to emergency sortie to clear Charleston harbor, but one boat, USS Narwhal(SSN-671) was undergoing significant engine repairs and couldn't get underway. The only solution was to submerge the boat at the pier, making her as heavy as possible with variable ballast, hoping that any storm surge wouldn't be strong enough to damage her. Fortunately, the bulk of the storm passed Charleston, and she made it through undamaged. But it could've been a lot worse - Mother Nature has a really bad temper and not respecting the damage she can inflict can be a really bad mistake.
How long is the Tsunami predicted to last in Hawaii?
Tsunamis typically last for several hours, with the most dangerous period being within the first few hours of impact. In Hawaii, authorities monitor the situation closely and issue warnings based on the specific characteristics of the tsunami, such as its size, duration, and potential impact on the islands. It is important to follow local authorities' instructions and stay informed during a tsunami event.
Will a tsunami ever hit New Jersey?
While it is rare for tsunamis to impact the East Coast of the United States, including New Jersey, they can still occur. The chances of a tsunami directly hitting New Jersey are considered low due to the region's geographic location and the sources of tsunamis typically originating from distant earthquakes or underwater landslides. However, it is important for coastal communities to have proper preparedness and evacuation plans in place.
If you are swimming in the ocean during an earthquake - can you feel the earthquake?
Water will create violent waves and if you continue to swim you might be pushed and flipped around. It might sound fun but it is really dangerous and can cause serious injuries. Trust me! Get out as soon as you can!
What is the biggest tidal wave ever recorded?
The two most famous (current) tsunamis are the 2011 Tohoku tsunami in Japan and the 2004 Boxing Day (Sumatra) tsunami.
The greatest historical tsunami (a series of them) accompanied the explosion of Krakatoa in August, 1883.
According to the US Geological Survey the maximum observed height of the tsunami triggered by the Chilean earthquake of the 27th of February 2010 was around 2.6 m (8.6 ft) near Valparaiso in Chile.
Please see the related link and question for more information.
The island that blew up in August 1883 was Krakatoa, located between Java and Sumatra in Indonesia. The eruption caused tsunamis that reached as far away as South Africa and Australia, and the sound of the eruption was heard thousands of miles away. The event resulted in the deaths of tens of thousands of people and had a significant impact on global climate.
In the context of electromagnetic (EM) waves, the terms "s-polarized" and "p-polarized" refer to the polarization state of the wave. In s-polarized waves, the electric field vector is perpendicular to the plane of incidence, while in p-polarized waves, the electric field vector lies in the plane of incidence. These terms are commonly used in the study of optics and are important in understanding how EM waves interact with different materials.
How do earthquakes and tsunamis change wildlife habitat?
Earthquakes can disrupt habitats by causing land movement, altering topography, and triggering landslides. Tsunamis can lead to flooding and saltwater intrusion, destroying habitats and displacing wildlife. Both events can disrupt food sources, breeding sites, and migration routes for wildlife populations.
Does a tsunami have magnitude?
There are Magnitude scales for Tsunamis, but you have to be a maths wizz to work them out, using the formula Mt = a log h + b log R = D.
Yes, the 2004 Indian Ocean Tsunami is an example of the impact of natural disasters caused by Earth's systems on human life. The massive waves triggered by an undersea earthquake led to widespread destruction and loss of life in multiple countries bordering the Indian Ocean.
Are the tsunamis in the world getting worse?
Tsunamis are not necessarily getting worse, but with increasing coastal populations and development in vulnerable areas, the impact of tsunamis is becoming more severe. Climate change and geological factors can also influence the frequency and intensity of tsunamis in certain regions.
disrupting the equilibrium of a medium, creating vibrations that propagate as waves. Wind can generate ocean waves by transferring energy to the water's surface. Earthquakes can produce seismic waves by releasing energy, which travels through the Earth's crust.
