What is natural disaster?
99112
Earthquakes, tornados, tsunamis, landslides, floods etc. are natural events not disasters.\n\nDisaster is the situation which the natural event interrupts the social and economic life and assistance from out of the affected area is needed to supply the basic human needs.\n\nEvery natural event is not ended with a disaster.Disaster is not only related to the force of the natural event but also the vulnerability of the affected area to that natural event. Men have no control on natural events but have control to prevent it to be resulted as a disaster.

man cant control natural disasters for many reasons. first of all humans dont know when such an event will occur. most of the time they realize only after the disaster starts. secondly they have no technology that can stop a coming tornado or tsunami or such disaster.

Naturally occurring earthquakes\n\nMost naturally occurring earthquakes are related to the tectonic nature of the Earth. Such earthquakes are called tectonic earthquakes. The Earth's lithosphere is a patch work of plates (see plate tectonics) in slow but constant motion caused by the heat in the Earth's mantle and core. Plate boundaries glide past each other, creating frictional stress. When the frictional stress exceeds a critical value, called local strength, a sudden failure occurs. The boundary of tectonic plates along which failure occurs is called the fault plane. When the failure at the fault plane results in a violent displacement of the Earth's crust, the elastic strain energy is released and elastic waves are radiated, thus causing an earthquake. It is estimated that only 10 percent or less of an earthquake's total energy is ultimately radiated as seismic energy, while most of the earthquake's energy is used to power the earthquake fracture growth and is eventually converted into heat. Therefore, earthquakes lower the Earth's available potential energy and thermal energy, though these losses are negligible. To describe the physical process of occurrence of an earthquake, seismologists use the Elastic-rebound theory.\n\nThe majority of tectonic earthquakes originate at depths not exceeding a few tens of kilometers. Earthquakes occurring at boundaries of tectonic plates are called interplate earthquakes, while the less frequent events that occur in the interior of the lithospheric plates are called intraplate earthquakes.\n\nWhere the crust is thicker and colder, earthquakes occur at greater depths of hundreds of kilometers along subduction zones where plates descend into the Earth's mantle. These types of earthquakes are called deep focus earthquakes. They are possibly generated when subducted lithospheric material catastrophically undergoes a phase transition (e.g., olivine to spinel), releasing stored energy—such as elastic strain, chemical energy or gravitational energy—that cannot be supported at the pressures and temperatures present at such depths.\n\nEarthquakes may also occur in volcanic regions and are caused by the movement of magma in volcanoes. Such quakes can be an early warning of volcanic eruptions.\n\nA recently proposed theory suggests that some earthquakes may occur in a sort of earthquake storm, where one earthquake will trigger a series of earthquakes each triggered by the previous shifts on the fault lines, similar to aftershocks, but occurring years later, and with some of the later earthquakes as damaging as the early ones. Such a pattern was observed in the sequence of about a dozen earthquakes that struck the Anatolian Fault in Turkey in the 20th Century, the half dozen large earthquakes in New Madrid in 1811-1812, and has been inferred for older anomalous clusters of large earthquakes in the Middle East and in the Mojave Desert.\n\nInduced earthquakes\nSome earthquakes are the result of a number of anthropogenic sources, such as extraction of minerals and fossil fuel from the Earth's crust, the removal or injection of fluids into the crust, reservoir-induced seismicity, massive explosions, and collapse of large buildings. These seismic events caused by human activity are referred to by the term induced seismicity. They however are not strictly earthquakes and usually show a different seismogram than earthquakes that occur naturally.\n\nA rare few earthquakes have been associated with the build-up of large masses of water behind dams, such as the Kariba Dam in Zambia, Africa, and with the injection or extraction of fluids into the Earth's crust (e.g. at certain geothermal power plants and at the Rocky Mountain Arsenal). Such earthquakes occur because the strength of the Earth's crust can be modified by fluid pressure. Earthquakes have also been known to be caused by the removal of natural gas from subsurface deposits, for instance in the northern Net

Plagues and natural disasters and earthquakes and floods and fire storms ......OMG the world is cumming to and end.

A tsunami is a wall of water generated by an underwater earth-quake. It is not related to the atmosphere in any way, and has no impact on climate in any way.

is disaster a choice?

Not really.  To some extent or another, every state usually has some sort of natural disaster you'd have to worry about at one point or another.  You do realize, of course, that the safer states are the ones with the natural disasters that don't occur very often... and yet, when they DO occur, it's for major damage?\n\nBesides.... if you wanted to live some place where there's it's completely safe.... then it'd be in Alaska.  I'm fairly sure there's areas up there where you wouldn't have to worry about too much snow - but then again, there have been earthquakes up there...  never mind.  I don't think there's any place on the EARTH where it'd be disaster free, unless you want to live in a deep cave protected against outside elements in the center of a tectonic plate.......!\n\nBut, you know, I used to live in Michigan, and we never had to worry about mudslides, volcanoes, avalanches, wind storms, tropical storms, hurricanes, earthquakes, or droughts.  Sure, we had the very occasional hail storm, very VERY occasional wind/ice storm, and every winter we'd get a nice snow storm sometimes a blizzard, and lightning storms were normal, but not very severe like down south, occasional floods... and twisters/tornadoes were not unheard of, either.  But nothing like in Kansas!  ... But I did see a couple there.... \n\nAnyway.  Just so you know, there's always something that can happen anywhere....

Should natural disaster occurs, natural selection occurs, as the species that adaptable enough to survive the natural disaster will continue their existance and those which not adaptable enough to survive these will be wiped out from the area.\nThose which able to continue their existance will inherit the traits that enable them to survive the natural disaster and of course, those who cannot survive will not have a chance to inherit their traits. \nThose will results to the increase of the "resistance" of the surviving species to the same natural disaster.

Whenever something catastrophic happens, a natural or man made disaster, and the local authorities can't handle the chaos, martial law is enforced.  Meaning the National Guard or other Military now act as police and government.  Usually they enforce a curfew, everyone indoors by 10pm, to cut down on looting and continued chaos.

Probably 100%. Its hard to determine this because nature is so unpredictable and if it could be determined, trust me, some scientist would have figured it out already. Nature kinda does what it wants to so its a chance you'll have to take. I dont know where you stay now, but with the whole global warming thats going on, its very possible that a natural disaster can occure there. There is no way of knowing.

a tsunami is caused by an earthquake deep in the ocean, and a hurricane is like a big tornato, thus meaning when hot and cold air meet, they swirl over the ocean and make a hurricane. \nhope i was of help!\nHappy Holidays, -creaive:)

When there are disasters in some parts of the world like tsunamis,earthquakes people get together to help the victims by providing funds,clothing,medicines,etc.This way natural disasters help to unite the world.

its a giant storm  like a hurricane thats been going on for a logn time bout size of earth i think

We had a natural disaster.  We learned for a period.  And then we went back to our normal habits.  We had a terrorist attack.  We learned for a period and went right back to our old habits.  Some one said to set an example.  And she is right.  If we do as we want to be treated its a start.  Teach our children these same values its a start.  If we think we a disposable, then we will be treated as such.  If we think we are replacable, then we will be.  See what I mean.  Examples and behavior is the key.  Its slow in coming but its the best we have.  Disasters dont teach us perminantly to change.  It takes patience.
