What is drifting of Land ? Give reason for tsunamis and earth quake became very frequent in todays world?

Question

In resent years we can find frequent earth quake and tsunamis but compare to earlier age . But if we see properly the defination of earthquake it is said that earthquake occures only in dry area but now a days this defination has gone wrong but seeing the tsunami effects .

Answer 1

earthquakes can occur anywhere two tectonic plates come together. i don't know where you are seeing that it only occurs in dry areas. i've never heard that before. if two plates cause an earthquake undersea. it can create a tsunami. look at the world when it began. it was supposed to be one huge continent. so the plates are always moving. thats how the earth moves, mountains, volcanoes and deep ocean trenches are formed. this is nothing new. maybe you would have a better understanding if you did some research on plate tectonics.

Answer 2

Keep in mind that solid land covers the entire earth--it's just that most (70%) of that land is itself covered by water. Our land masses are merely the portion of land that has a higher elevation than sea level.

Continental drift is the very slow, creeping motion of our land mass, due to "convection currents" of the semiliquid lava material deep within the Earth.

All of our land mass used to be connected, in a continent called Pangaeia, but that has slowly spread apart over hundreds of millions of years.

There probably is not any greater earthquake, tsunami, or volcanic activity in modern times, as in times before. It's just that now, we have worldwide communication, and so everyone is aware of anything that happens , overseas and on the "other side of the world".

Every day, a volcano blows off, somewhere. Most are small. Same with earthquakes.

There are undersea quakes, and volcanoes. We hardly notice them, because we are humans and live on dry land.
We don't build our cities in the oceans.

Answer 3

Earthquakes have always happened throughout geological history,they always will, there is one every day somewhere, even if it is only a minor tremor. The Alaskan earthquake of 1964 actually occurred off the coast. i.e. under the sea. It is through the interaction of the tectonic plates. At a constructive margin, (i.e. where plates move apart ) a destructive margin (i.e. where plates move together) or along a conservative margin ( i.e. where plates slide past each other a la San Andreas ) The whole mechanism is driven by the convection currents of the mantle rocks. If it was not for these movements there would be no mountains.

Answer 4

Actually the exact reason for earth quakes is the land moves in the interior of the earth coz for every 100 million years the land moves abt some inches closer in the world.so in only some places earth quakes occur.Land moves inside and the movement when it comes to the surface occurs as earth quake.

Answer 5

Actually, you're talking about drifting of the continental plates (which the land is on). As to the increase in earthquakes and tsunami's??? Who told you that? We find them more frequently, but only because we have better detection equipment. But not necessarily so in earth's history. In fact, there were probably a lot more back in "the old days" than there are now. And earthquakes DON'T only occur on dry land.

Answer 6

it is not necessary that tsunami will occur only when an earth quake happens underwater.volcanic eruptions also cause it sometimes.i think the displacement of water during an earth quake makes high tides due to which tsunami occurs

Answer 7

No..
Earth quakes & tsunamis are not more frequent than in the past.
They are simply reported more often & accurately...

Answer 8

God states that it is He and He Alone, Who gives the Earth it's command to "shake". Whether that command is,"Zilzaal",or,"Sayhah!".
