Seismic sea wave becomes more dangerous as it gets closer to shore and can be very destructive?
Tsunami
Where in Japan was first hit by the Tsunami?
The first recorded tsunami that hit Japan occurred off the shore of the Kii Peninsula, Nankaido, Shikoku, Kii, and Awaji region. It has been estimated to be a magnitude 8.4- Nancy-
Why do most oceanic quakes not form a tsunami?
Well first of all earthquakes form tsunami's because the ground is shaking and being broken up which makes the water uneven and cause the water to move and the more closer it gets to shore the more shallow the water is their and will cause a tsunami.The main reason is that the underwater earthquakes are not strong enough to generate a tsunami.Additional answerWhen one tectonic plate slides over the top of another suddenly the sea floor rises abruptly, pushing all the water directly above it upwards. This causes the tsunami. But not all plate movements are large enough to cause a tsunami.
Earthquakes are frequent in California US so is California prepared on their beaches for Tsunamis?
There is a system of tidal buoys that are designed to detect tsunamis before they hit the shore, but a tsunami caused by an earthquake along the coast would hit the beach before any alarm could be given.
What effect does slowing down in speed have on the height of tsunami waves close to shore?
The effect of the slowing of a tsunami close to shore is that the wave increases in height. It becomes a lot taller! The trick to getting this in perspective is in understanding that as the wave travels across the water, it stretches out. As it is now longer while en route across the open ocean, it isn't as tall. In fact, it is possible to be on a ship in the middle of a deep ocean as a tsunami passes and not really notice anything alarming because the wave is so elongated. As it reaches shore, the leading edge of the wave begins to slow up in the shallower water. This results in a "bunching up" of the water and the wave can then rise to a frightening - and destructive - height just as it comes ashore. To expand a little: Ordinary ocean waves are movements only of the top layers of water, and if you were diving a few meters below the surface, you would not feel the effects of even rather strong waves. Tsunamis, however, involve the movement of truly huge amounts of water amounting to the entire "column" of water from the ocean floor to the surface. This is another way to see why the above explanation increases tsunami height. We're not talking about bigger and bigger "surfing" waves, but a huge volume of water crowding up on itself as it moves over the rising ocean floor.
Why did the Japan tsunami happen?
Because of an Earthquake that happened which displaced a lot of water causing the tsunami.
Is California going to be under water due to a coming tsunami sometimes soon?
No. While California does sometimes get tsunamis, the whole state will not be flooded. When a tsunami strikes it is the low-lying areas near the shore that will get flooded. Areas that are high up or more than a few miles from shore will be fine.
Can a tsunami bring sharks on shore?
Yes. All manners of marine animals can be brought on shore by a tsunami. Note, though that a shark brought on shore by a tsunami would be stressed enough that it would not be interested in eating.
Is a tsunami highest when its in the middle of the ocean?
No. A tsunami is highest in the shallow water near shore.
What happens to a shore when a tsunami hits?
It disappears until the tsunami dies away. I don't know what happens to a tsunami but this is what I think.
What happens to a tsunami as it nears the shore?
It becomes bigger :)
How does the speed of the tsunami wave change as it approaches the shore?
The wave would slow down as it approaches the shore.
How does the speed of tsunami wave change as it approaches the shore?
The wave would slow down as it approaches the shore.
What can be done during a tsunami to minimise the damage?
Not live near A shore.
What happens to tsunami's as they move toward shore?
Their wave size increases.
Safety precaution in tsunami?
When a Tsunami occurs dig big pits near the sea shore as the speed and the quantity of water will get reduced.
What does tsunami mean in hawaiian?
a tsunami is sort of a hurricane in the disaster family ,but a tsunami is a seismic sea wave that brings over an earthquake focus and can be highly destructive when it crashes on shore.
