- Mega-tsunami, what is the greatest possible height of a tsunami?
The notion of a taller-than-skyscraper, so called "megatsunami" is not new - with the often-reported 524m (1720 feet) high Lituya Bay tsunami of 1958 is sometimes referred as such (despite the wave
- Can climate change cause earthquakes, tsunamis, or volcanic eruptions . . .
Different scientists have brought forth a theory that climate change can cause earthquakes, tsunamis and volcanic eruptions For example: Professor Bill McGuire of University College London in his book Waking the Giant: How a changing climate triggers earthquakes, tsunamis, and volcanoes (OUP, 2012)
- Is it possible for tsunamis to occur on deep water planets?
Tsunamis occur in the wake of large earthquakes They grow in amplitude because the speed of a water gravity wave is influenced by water depth, causing the wave to 'pile up' In particular, if the wavelength is (much) greater than the depth of the water, the speed at which a wave will travel is roughly:
- Why does the shoreline sometimes recede prior to a Tsunami?
It is well known among regular beach goers that a sudden shoreline drawback is often a warning sign for an impending Tsunami My understanding of Tsunamis is they they form as a result of the seafloor abruptly changing, causing a local vertical displacement of water at the site of above the disruption, which initiates the wave
- How much time is there between an underwater earthquake and the moment . . .
Tsunamis out in the deep ocean travel very fast -- around 500 mph -- which means that they cross ocean basins in about as much time as it takes a plane to fly across So an earthquake in Japan gives Hawaii and the US West Coast many many hours of warning Close to shore, tsunamis are much slower, but of course the distances are also shorter
- measurements - How accurately can a tsunami be predicted? Have there . . .
The ability to predict depends on the cause of the tsunami Earthquakes can't be predicted, so a tsunami caused by an earthquake can't be predicted
- Why do Tsunamis travel slower than sound?
$\begingroup$ In short, tsunamis are usualy caused by a net movement of the ocean floor, which typically rises several meters over a large area That displaced water bulges over that area and then flows sideways as a very shallow wave (in the order of centimetres, hardly noticable over the normal wind wave s) which only increases in height as
- climate change - Does global warming affect tsunamis? - Earth Science . . .
Tsunamis are caused by water displacement due to earthquakes; this has nothing to do with global warming Any changes in density would be trivial, and although the water would have more thermal energy, this would not affect or be influenced by the kinetic energy of the Tsunami
