On the way in, they look like a series of waves, but usually really, really big ones. Depending on where you are, it could look like a massive wave or a wall of water coming rapidly your way.
On the way out, they almost don't even look like water sometimes because of all the debris they have picked up.
See the related link below for pictures of one particular tsunami and the aftermath.
The water looks calm initially. However, if a tsunami is caused by an earthquake, a slight rumble can be heard, and the ground might shake. As the waves approach shore, the water near the shore will recede dramatically, following a 'sucking* sound'. A clear rumble should be heard. The fast moving waves will start to get higher as the seafloor gets shallower near the coastline. This forms a tsunami and the waves will crash onto shore and rush inland. *Note that 'sucking' means being sucked in, and is not a vulgarity. Also, the water levels will drop just before the tsunami hits.
A tsunami is a massive wave that is very strong and powerful. It is caused by a major disturbance underwater which causes the water unexpecteldy rise or sink. There was a landslide in Lituya Bay and it caused a 518 tsunami. ( True fact )
In open ocean it doesn't look like anything. At this point it is likely no more than three feet high and is dozens of miles long. A person on a boat would not notice anything unusual. As the tsunami enter shallow water it increases in height, becoming a massive surge of water.
After a 8.9 earthquake struck Japan on March 11, 2011, huge tsunami waves struck the island nation.
When tsunami waves hit the coastal towns of Japan it covered the land and pushed cars, trucks, even houses over like they were small toys.
See the related link below to see live footage of the tsunami hitting Japan.
When tsunamis strike an area, they are usually massive to be seen from human eyes, they are sort of giant waves pouncing in the civilization. The geologists, climatologists, meteorologists have been able to create an ideal structure for the tsunamis which resembles a hyperbola with crests and troughs.
A tsunami looks like a wall of water just before it hits. How tall and how big the wall of water looks like depends on how big the underwater quake was, the geological features of the area, and the distance the wall of water must travel before it hits land. A huge earthquake might only produce small waves.
Tsunamis are giant tidal waves usually caused by earthquakes in the oceans
it looks like a huge wave
i would say earthquakes but there are more reasons edit: Tidal waves are the byproduct of undersea plate tectonics. Subduction zones create large amounts of friction which then in turn create seismic waves which are transferred in to the surrounding sea water and take the form of fast moving waves in the open ocean. When the water becomes more shallow is when you see the classic images of a tsunami or tidal wave.
The Intertidal zone, Coastal Ocean, and the Open Ocean
The open water zone reaches down to where sunlight can still penetrate. Organisms that live here include tadpoles, fish, and non deep-rooted plants. Phytoplankton is the most abundant organism here.
An ocean is just a vast expanse or quantity of water. As a result of this explanation it seems that there is no difference between an ocean and a sea.The word Ocean derives from the Latin 'oceanus' and the Greek 'okeanus' which was thought to be a great river or sea surrounding the disk of the Earth. Oceanus was the son of Uranus and Gaia. This comes from early times when only the large land masses of Europe and Africa were known and the Ocean was an endless river that flowed around them. In later times the name was 'ocean sea' and later still when exploration discovered even larger bodies of water did the term 'ocean sea' divide into 'sea' for smaller bodies of water and 'ocean' for the largest There are now five Oceans, Atlantic, Pacific, Indian, Arctic and Antarctic
does it look like I know the answer,, you should open the book up and start reading and studying like normal kids............ that's how you get good grades........you guys cant be stupid enough not know the answer ok well bye c: c; love yall "
Not in the deep open ocean. Out there a tsunami will pass unnoticed under boats.
In open ocean, yes. A cheetah can move at 60 to 70 mph. A tsunami in open ocean can move at 500 to 600 mph.
With the right instruments, yes. However, if you were on a boat in the open ocean, you would not notice any disturbance.
None in the open ocean because in the open ocean the tsunami waves are not very large. They only build as they hit shallow water.
23 mph
Most likely not. A whale in deep, open ocean water would probably not even notice a passing tsunami. In shallow water it would be a very stressful event.
Tsunamis in the open ocean are not dangerous at all; they aren't even noticeable. In deep ocean water a tsunamis is only a few feet to a few inches high and dozens of miles long. It is only when a tsunami reaches shallow water that it gains height.
To a limited degree yes. If an earthquake of 6.5 magnitude or greater occurs underwater a tsunami watch is issued. If buoys detect the tsunami as it travels though open ocean a tsunami warning is issued.
Because width doesn't matter in a tsunami. The width is typically the length of the shore. It would be extremely difficult to classify a tsunami based upon height and width when the width is simply incomparable.
the open ocean is a place where u can swim
Tsunamis can travel over 600 mph in the open ocean. It can only take a few hours for a tsunami to travel across an entire ocean. A regular wave travels at 90 km/hr. http://www.enchantedlearning.com/subjects/tsunami/
