Mega Tsunamis . Such wave of huge proportions will be probably triggered in the Atlantic Ocean anytime in the next 5. East Coast of America, North Africa and Europe. Image: Mega- Tsunami: fiction picture gives an idea of wave height. Waves of this type are called Mega Tsunami . They are so great that they can reach several hundred meters in height, travel at the speed of a jet aircraft and get up to 1. Kilometers) inland. Video: Mega- tsunami: Wave of Destruction . Unfortunately, as seen in the documentary above, there is a concrete possibility that it will occur again in the near future. A mega- tsunami has almost unlimited power to cause utter destruction and there's nothing we can do to stop it. Even the most powerful waves, the tidal waves known to science by their Japanese name Tsunami, cannot create such destruction. A mega- tsunami is an informal term to describe a tsunami with initial wave amplitude (height) much larger than usual tsunamis. Mega- tsunamis are several tens, hundreds, or possibly thousands of meters high and they are able to cross oceans and ravage countries on the other side of the world. Generally, a tsunami is caused by an earthquake near the shore or underwater. The biggest submarine earthquakes can shift the ocean bed up or down by around 1. Normal tsunamis created by an earthquake on the ocean floor have only small wave heights while off shore. However, the height of normal tsunami waves increases dramatically when they reach land as the base of the wave pushes the water column on top of it upwards. So, what kind of event can create a mega- tsunami? Unlike usual tsunamis, mega- tsunamis are caused by giant landslides and other impact events such as volcanic eruptions or huge asteroids crashing into the sea. These phenomena rapidly displace large volumes of water, as energy from falling debris or expansion is transferred to the water. Huge earthquake- induced rockslides next to bodies of water can generate mega- tsunamis since the massive amount of water displacement increases the wave size more than a submarine earthquake. Luckily, huge landslides and the mega- tsunamis that they can generate are extremely rare. In most cases, tsunamis caused by rockslides, unlike the ocean- wide tsunamis caused by some underwater earthquakes, dissipate quickly and rarely affect coastlines distant from the source due to the small area of sea affected. However, a massive landslide can give rise to much larger local shock waves (solitons = solitary waves that can travel for long distances without changing their shape or losing energy).

Northwave is leader for Cycling Clothing, Bike Wear, Cycling Clothes and Accessories, Specialized road bike shoes, MTB cycling apparel and eyewear. Italy Votes in Landmark Referendum Ballot on Prime Minister Matteo Renzi’s reforms sees political establishment face off with populists. That is the case when a massive landslide occurs in a limited body of water and the resulting wave is unable to disperse, just as it happened in Alaska where a major rock fall generated the Lituya Bay tsunami. It was the largest tsunami wave ever observed anywhere in the world and it was caused by a rock fall in Lituya Bay, Alaska on July 9, 1. Image: Mega- Tsunami: An earthquake- induced rockslide, shown in upper right- hand corner of this image, generated a 5. The mega- tsunami razed trees along the bay and across La. Chausse Spit before leaving the bay and dissipating in the open waters of the Gulf of Alaska. Video: BBC Nature: Mega Tsunami - Evidence of Destruction. Video: BBC Nature: Mega Tsunami - Alaskan Super Wave - Amazing Survival The Lituya Bay mega- tsunami was triggered by an earthquake with a magnitude of 8. Alaskan Fairweather Fault, which runs beneath the north- western spur of Lituya Bay. A massive volume (approximately 4. Gilbert Inlet sloughed off into the water, generating a wave which reached the incredible height of 5. Down the inlet itself, the initial wave reached a height of 6. Five square miles of land surrounding the bay were inundated and stripped of all vegetation and wildlife. The tsunami sunk three solitary fishing boats anchored in the harbour and moved inland as far as 3. However, the tsunami's energy and height diminished rapidly away from the source area and, once in the open ocean, it dissipated and was hardly recorded by tide gauge stations. Image: Mega- Tsunami: The 1. Lituya Bay was rather large! The following video explains how a massive landslide can generate a mega- tsunami: Video: BBC Nature: Mega Tsunami - Landslide Analysis On October 9, 1. Lituya Bay disaster, an enormous landslide of about 2. Vajont Dam on Monte Toc, Italy, at up to 1. The resulting displacement of water caused 5. The flooding destroyed the villages of Longarone, Pirago, Rivalta, Villanova and Fa. More than 2,0. 00 people (some sources report 1,9.

The 2. 00–2. 50- metre wall of water that overtopped the dam and destroyed the village would have obscured virtually all of the sky in this photo. The following video shows a physics- based computer simulation of a landslide mega tsunami in an alpine reservoir.
