Questions tagged [tsunami]
a long-wavelength, high-energy, surface wave on a body of water, usually generated by geological forces. Tsunamis are also called "tidal waves" because their approach causes substantial amounts of water to recede from the shoreline in a manner reminiscent of the tide going out. The inland surge when the wave breaks can be highly destructive.

Converting starting wave to known max wave height
in our university project, we are developing a tsunami simulation using the Shallow Water Equations. For our project, we have decided to allow users to enter an epicentre and the magnitude of an ...

Can someone explain why waves shoal?
So, I was talking about Tsunamis with friends and as I started looking into it, I learned about the phenomena of shoaling. As water begins moving from deep areas into shallow areas, the waves increase ...

Wave transmission in underwater slope
A typical tsunami has wavelengths comparable to continental slopes. So surely reflection plays a significant role in determining runup.
So consider a wave of small amplitude A1 and wavelength l1 ...

Do tsunamis accelerate on land?
Before they saw the footage, Fritz and Synolakis couldn't understand why so many people had taken photos posing with the wave behind them, out on the open ocean. For some victims, those pictures would ...

Why amplitude of tsunami increases as it tavels ashore?
I read that there is a displacement between 2 (oceanic) tectonic plate and this drop cause a big potential energy on the wave directly above, I don't buy it because obviously many video footages ...

Can you only predict a tsunami 50% of the time on the beach?
I am quite sure my professor claimed, that you can’t always predict a tsunami incoming on the beach by looking at the water pulling into the ocean.
She said that’s only possible 50% of the time, ...

Question about the difference between a tsunami caused by a meteorite and one caused by an under water earthquake
Picture the situation where a meteorite falls somewhere on one of our oceans and gives off all its kinetic energy to the water (let's ignore the thermal energies involved like, for example, the heat ...

How to survive a direct hit of a Tsunami?
It's probably a question too general for this forum, but I'm not sure.
The other day, I was in the beach, near the sea, and a big wave came towards me. So, instead of running from the wave, I decided ...

Tsunami effects of a nuclear explosion
Sea surface nuclear explosion arouses a tidal wave of water.
How does this kind of wave compare to naturally occurring tsunamis? E.g. what would be the potential of a 100KT bomb 100km away the from ...

Fluid dynamics tsunami
I have been given a energy head (pressure) in meters for a given tsunami on land.
If the tsunami hits a wall 1 meter by 1 meter, is it possible to calculate the height it will reach.
I am thinking it ...
