Earthquake - earthquake
Oh, yeah, there are plenty of earthquakes under water. There are faults under the ocean just as there are on dry land. You're exactly right, that's how tsunamis happen.

Plenty of disturbances do happen under the water and things like tsunami will happen very rarely and when it does happen, it also effects maximum and something has to be done atleast to know before it strikes and now steps are being taken and if this comes out true and future tsunami's predicted, then it will be good for human kind as they also can get ready for the situation and act accordingly........ Anyway's, thanks for responding

I never heard it before.. I only came to know when that disaster thing happened.. Quakes do occur underwater, and when they come they are very dreadful, even stronger than quakes on Earth..

Yes, quakes occur under wtaer but most of the times, the magnitude will not be that high and when the magnitude of earthquake is more, things like Tsunami occurs and recently it created an havoc which will be remembered for very long time. Anyway's, thanks for responding

yes earthquakes may occur at any part of the earth wether it is land or ocean. this is bcoz of the distturbances in the core of the earth which plunges lava out from very sensitive parts

Yes, rightly said.Everybody still remembers the havoc created by Tsunami which occured due to the earthquake of high magnitude under the water with waves riding at almost 100 feet height and this was very scary and also destroyed everything on the way. Anyway's, thanks for responding

Yes the earthquake occurs under water also. The reason behind it depends upon the understanding of how earthquake occurs?? Earth crust is divided into many tectonic plates and these are always moving across each other. whenever the pressure increases while the plates are moving in opposite direction then the earthquake occurs. If you have observed that most of the boundaries of the tectonic plates are under the sea hence more earthquake occurs under the sea than on the surface !!

Oh...yes, you are absolutely right and thanks for giving out this valuable input here.Tsunami occured recently isn't it resulting in major disastar and many of them lost their lives and now they are almost on the way to install Tsunami indiactors which will help in indicating the Tsunami strike before it actually happens and maybe many lives can be saved if it strikes again...isn't it? Anyway's, thanks for responding

If you are not sure, then let me tell you that earthquakes occur more under water than in land as 3/4th of the earth is covered by water isn't it? and when this earthquake under water is of severe magnitude, Tsunami will occur resulting in higher waves with more speed and more distructive... Anyway's, thanks for responding

They most certainly do occur under water and thats exactly why tsunami's occur. I think most of them can be tracked and people can be warned but theres such vast amounts of oceans that all of them probably cant be tracked all of the time. I heard about one on CBC that had occured and they tracked it for a day or so before reporting that it would not result in a tsunami.

Yes, Tsunami occured recently because of severe earthquake inside water and waves of height more than 100 feet travelling at a tremendous speed distroyed some parts of srilanka, india, indonasia etc and now they have progressed in installing some Tsunami indicators which will help in detecting Tsunami before striking...

Yes earthquakes keep on happening under sea water , this is what causes Tsunami waves.

Tsunami is caused only when severity of earthquake is more and doesn't show any effect when the sevrity is not that much and usually as you said, earthquakes do happen more under the water than over.... Anyway's, thanks for responding

Tsunami doesn't occur regulary.But, earthquakes under water is quite common and severity is not that much and when the earthquakes are of severe magnitude, this tsunami will come to effect and it is very distructive as everybody know's isn't it? Anyway's, thanks for responding

Earthquakes occur more in water than in land part and it is simply justified also since water constitutes 3/4 th of earth and earthquake under water won't be of severe magnitude and so in most of the cases it won't be known also and sometimes when the severity of earthquake is more, it will have distructive results and will be known to all...isn't it? Anyway's, thanks for responding

yes my friend that is exactly tsunami.ofcourse tsunami.earthquakes that occur under water that lifts the sea water and blows the land off.it happened in our state but our p[lace it was ok.we live above sea level.my native was flooded.

Did you get to see it live or have you also seen the video footage in tv? how much it got effected in your place? i mean, not exactly your place but near to your place? we can just pray and hopethat such Tsunami's doesn't occur again..isn't it? Anyway's, thanks for responding

Ha Didnt you heared of the great Tsunami , the huge waves in the sea which devastated souther India, Sri Lanka and Indonesia. That was caused by the earthquake under water.

Tsunami is known to everybody now and i have also seen some video shots of Tsunami that occured in some parts of srilanks, india etc and it's so shocking and anyone involved in that and got rescued will be having a worst life time momory which he cannot forget.... Anyway's, thanks for responding

Yes, earthquakes also occur underwater, and that shaking leads to tsunami, tidal waves... that's why when an earthquake occured in a place near sea or ocean, the government gives tsunami warning to those places or countries that can be affected...

I don't think government is accurate in giving Tsunami warnings as still it is in the testing stages and in coming years, they are installing some tsunami indicators to indicate the tsunami beforehand and so much is spent for this all over the world and it would be interesting to see how much it will be effected in coming years....

Underwater earthquakes are very common and man made the connection between the big waves and the earthquakes a long time back. Japanese from a long long time would run to higher ground as soon as they felt a quake! Ancient Japanese were the first to record Tsunami (it is both plural an singular in Japanese) and to find the connection between earthquakes and Tsunami. Tsunami is a Japanese word meaning Harbor wave! Interestingly not all underwater earthquakes lead to Tsunami and also all Tsunami are not caused only from earthquakes. A massive ice ridge collapsing into the sea in Antarctica or the arctic can set off a tsunami. A tsunami can also be set off by a volcanic mountain collapsing into the sea.

Yes, underwater earthquakes are very common and most of the times it won't be known also as the magnitude will not be of that high range and only when the magnitude of earthquake under water is high, things like tsunami will occur where the waves will be of more than 100 feet and travelling wit more speed and hence it is most distructive and also scary to watch and i also though all earthquakes of severe magnitude under water will lead to tsunami and it's nice to know that a massive ice ridge falling into antartica also causes Tsunami..

oh well it is called tsunami :) hawaii is too much affected to tsunami's are enormous!! When an earthquake happens underwater, is shakes the surface below thus the water moves a lot more harder than producing small waves but big and huge waves. Thats so scary to see a big buge and giant waves heading towards you...ever imagine that???

I have seen a video footage if the recent Tsunami which occured in some parts of Srilanka, India ,Indonasia etc and as you said the gigantic waves are really scary and feel bad for the sufferers isn't it? may be some steps are already taken to identify such tsunami's that might strike or on the way....it will be good to know beforehand isn't it? so that we can get ready for the situation and maybe so many lives can be saved isn't it?

What is this you are telling here...i cannot understand..would you elaborate or explain a little bit more? are you telling me that earthquakes under water are very rare or earthquakes doesn't happen regularly ? Anyway's, thanks for responding

Yes we learned about these and the dangers they have when I was in school over 15 years ago. We learned of one big Tsunami back in world war II, that hit one of the Islands in Hawaii and wiped out the whole Island but for one woman. It was sad because there was an orphanage there. But yes earth quakes happen under the sea almost as much as they do on land, but the shift of the floor bed is not the major most of the time.

Earthquakes happening under the sea will be more regular than over the land and things like tsunami doesn't occur regularly and the tsunami that occured during world warII is the worst one as you said and now some steps are taken to detect earthquakes like tsunami before it occurs and in some years this detection system might work Anyway's, thanks for responding

Many earthquakes that occur under the ocean are close enough to land that the shaking from the earthquake will cause some damage. Large earthquakes in the oceans can also cause movement in the ocean floor that creates tsunamis (sometimes incorrectly called tidal waves). There are some anecdotes that have claimed that animals can detect something prior to earthquakes, but there are no cases where scientists have been able to confirm this

Well said and i also heard to the old people story of saying that animals do detect earthquakes and even today there are people who believe in this and i also say that there should be something about old people commenting like that as, "without fire smoke come out isn't it?" Tsunami's are the worst thing happened in recent years.... Anyway's, thanks for responding

Experts say that an earthquake can either be tectonic in origin or volcanic. Tectonic when there is a movement of plates and since a plate covers a wide area most of it are underwater. A sudden downward movement of a plate sucks the water downward thus creating huge waves or movement in water creating tsunamis. They also say that there are more volcanos under water than on land. And so the same principle applies.

Oh.you have given some real reasons for earthquake here and water being covered as major part in this earth,earthquakes will be mostly occuring under water and sometimes when it is severe, effect will be more which will create tsunami. Anyway's, thanks for responding

Tsunami was the major disaster occured recently and whenearthquakes is severe under water, tsunami will arise but usually earthquakes under warer will not be of that much effect and once tsunami occurs, water will raise upto 100 feet high travelling at a severe pace.....
