what can cause tsunami?

Answer 1

Everything that you ever wanted to know about tsunami can probably be answered in the reference below. I live in Crescent City, California which had a 2-meter tsunami after the Kiril earthquake a few weeks ago. The harbor completely emptied, and had it not been low tide lives would have been lost.

The town was not so fortunate in 1964 when a good portion of the town was destroyed by tsunami. We have a tsunami warning system that is a series of sirens that sound like the "air raid" signal you would hear in a war movie. You should ask how warnings are issued. All of the dead in our 1964 waves could have been saved but chose to ignore the warning or deliberately went toward the harbor to view the wave. The important thing to know if you are in a Tsunami zone is to move IMMEDIATELY to higher ground if the earth shakes or a warning is issued. It is probably best to travel on foot as roads become congested - this has proved true in our own tsunami drills. In some instances a "vertical evacuation" to a higher level of a building is recommended, but the out-surge of tsunami can be so powerful that this should be considered a second-best alternative.

Answer 2

reasons Tsunamis may be generated whilst the sea floor all of sudden deforms and vertically displaces the overlying water. Such super vertical strikes of the Earth’s crust can take place at plate limitations. Subduction earthquakes are quite effectual in producing tsunamis. As an Oceanic Plate is subducted below a Continental Plate, it now and back brings down the lip of the Continental with it. finally, too lots rigidity is positioned on the lip and it snaps back, sending shockwaves in the process the Earth’s crust, inflicting a tremor below the sea, often happening as an Undersea Earthquake. Sub-marine landslides (that are actually and back extra on via super earthquakes) besides as collapses of volcanic edifices might additionally disturb the overlying water column as sediment and rocks slide downslope and are redistributed around the sea floor. further, a violent submarine volcanic eruption can uplift the water column and type a tsunami. Waves are shaped through fact the displaced water mass strikes below the effect of gravity and radiate around the sea like ripples on a pond. interior the Fifties it replaced into got here upon that larger tsunamis than in the past believed available must be led to via landslides, explosive volcanic action and result activities. those phenomena at present displace super volumes of water, as potential from falling debris or enhance is transferred to the water into which the debris falls. Tsunamis led to via those mechanisms, no longer in basic terms like the sea-huge tsunamis led to via some earthquakes, frequently burn up rapidly and not often influence coastlines distant from the source through small portion of sea affected. those activities can provide upward push to lots larger close by ask your self waves (solitons), such through fact the landslide on the top of Lituya Bay which produced a water wave expected at 50 – a hundred and fifty m and reached 524 m up close by mountains. in spite of the shown fact that, a very super landslide ought to generate a megatsunami that should have ocean-huge impacts. you ought to get greater information from the link under...

Answer 3

Tsunamis generally are caused by earthquakes, less commonly by submarine landslides, infrequently by submarine volcanic eruptions and very rarely by a large meteorite impact in the ocean.

Answer 4

Mostly natural causes, like earthquake, underwate volcano eruption, landslide, etc.

Answer 5

the movement of the earth below the water

Answer 6

I believe its an underwater earthquake. In more detail I don't know.

Answer 7

earthquakes,being prone to them

Answer 8

Plate Tectonis..............or fat dudes cannonballing.
