what is effect of earth quake on building?

structures are subjected to 2 types of movement in an earthquake, P-wave and S-wave. P-wave is the sharp up and down movement, called the primary wave. S-wave is the longer lasting side to side movement, called secondary waves. then there are the after shocks. PBS NOVA has several well made documentaries about that stuff.

I am sitting about 4 miles from the Palmdale Bulge. We have been overdue here in Southern California for a quake along the San Andreas for about 30 years.\nWhen it hits, it's gonna be MASSIVE, in the high-7's or low-8's at least.\n\nBy the way, earthquakes have NOTHING to do with the weather. There's no correlation between hot days, cold days, or any other meteorological phenomena and earthquakes. Also, earthquakes are NOT a judgement from God. They are an effect of plate tectonics and geologic stress.\n\nIf you'll forgive the following monologue:\n\nVirtually the entire Pacific Coast of our hemisphere rests on a series of geologic faults. One of the most unstable of these is the San Andreas Fault, running 600 miles through the state of California.\nSome sections of the fault are slipping. The two sides are sliding past each other, slowly. The strains accumulating are being dissipated rather harlessly, without generating large earthquakes.\nAt two points, however, the sides of the fault are locked, permitting no slippage. Elastic strain energy is being built-up. Invisibly, the land is being compressed and warped, storing energy like a colossal spring under the crust of the Earth. Many scientists feel this energy will break lose, and a cataclysmic earthquake will occur within the next decade.\nOthers feel it could happen tomorrow.\nOne of the critical points is north of San Francisco, the other just a few miles east of Los Angeles.

Nothing in particular. There is a big 'boom' (with no sound because there is no air to vibrate) and there is a lot of light and a release of radiation, but that is about it. Basically, take an explosion on earth, and take away the earth, and voila.

due to the tremendous pressure from inside the earth or due to the presence of faults , takes the adjustment of tactonic plates , this results in movment of one plate into the other or just simple movements resulting in tremors caleed earthqukes

Mostly flexible structures.\nBuildings that are built to bend or move with the tremors, Bridges that can twist. If the structures can flex then they do not break (Cocktail stick versus rubber band). Some buildings collapse when they resonate (vibrating in tune with the earthquakes) Building designers can use different materials or different designs to stop resonance. Round buildings instead of square, thicker or thinner walls or make buildings modular ( like bricks stacked on top of each other.

With no solid surface for either of these planets, an 'earth'quake would not happen in the traditional sense.  I am sure that there must be some incredible turbulence throughout the entire fluidic interior of the planets, and especial with Jupiter, the core may be solid and made up of metallic hydrogen.  I expect when comet Schumaker-Levy 9 slammed in to Jupiter, it must have set of some tremendous shock waves, but the planet aborbed it with barely a flinch.

I'v heard about buildings being put on ball bearings so that the building will remain stable while the earth rocks beneith it. I'v seen a few specials on the Discovery Channel about it. Apparently the technology was pioneered in Japan. It makes sense since Japan has A LOT of earthquakes.

There are many factors that would determine whether your house would be knocked down by an earthquake or not.\n\nThe most obvious would be the size of the earthquake and your distance from the epicenter. The amount of destruction tends to drop off rapidly with distance from the epicenter.\n\nThe next factor would be what your house is made of.  Wood frame structures tend to stand earthquake stress more readily than a masonry (brick or concrete) building would because the joints between the wood can flex and return to their original form whereas bricks will break apart.  The age of the structure and any earthquake retrofitting will also be a factor.  In homes, one of the most common retrofits is to bolt the house to the concrete foundation so it won't slide off during a quake.\n\nThe third factor is the ground under your house.  There are certain soil types that can magnify the force of the earthquake.  An example of this is the Marina District in San Francisco.  It is largely built on top of debris from the 1906 quake.  During the Loma Prieta quake, the relatively loose rubble vibrated and shifted causing extensive damage to the buildings atop it.

You could use a saltine cracker box and use 4-6 springs glued onto the bottom and on the other end of the springs glue a wooden block.  The wooden block would be buried in the soil as well as the springs.  When an earthquake hits, the building moves on the springs instead of cracking and falling.\n\nBy the way, that is an actual construction used in earthquake resistant buildings.

Partly.\nThe increasing emission of Green House gases in causing Global warming which is making the world's climate go topsy-turvy\n\nNow you have Summer heat waves in Europe, Snow fall in Dubai, the killer Hurricanes\n\nPerhaps it is time for Mankind to step back and think as to why these are happening\n\nBut I should state that Earth Quakes are not quite related to this effect (but then again, you would never know)

No, not a chance.\n\nThe frequency of Earthqakes is determined by the stress and strain along fault planes of which occur at plate boundries and pretty much anywhere there are rocks. The occurance of a earthquake is determined by the maximum stress at a given point along the fault plane. Some parts of the falut plane potentially are weaker than others. \n\nVolcanic activity is governed by the increase in pressure in the lava chamber,mechanical strength of the rock matter and the seperation of plates from each other. \n\nDrilling into the earths lithosphere does not increase the volumes of these two naturally occuring events. In terms of drilling, usually in the deeper section of the well the size of the hole is mainly 8 1/2" however can sometimes be smaller. During planning of the drilling it is very important to avoid hazards such as faults as they cause untold problems for the stability of the well. (We use a special type of mud to reduce the potential of the well collapsing) A typical well is approx 3000meters or 10000ish feet, however that does not mean to say that we are drilling the hole vertically, it also takes into account the horizontal distance drilled.\n\nFor my thesis in my final year at university, I studied the re-activation of ancient fault planes into recent sedimentary layers and also mapped the occurance of recorded faults in my study area. What I concluded from this study was that recent climatic events i.e the last ice age that swamped a large part of the northern hemispere, caused a massive strain in the earths crust due to 'ice loading'. The result of the removal of the ice saw the 're-bounding' of the earth - pretty much like if you squeeze a sponge it returns it shape. This phenoma is called isostatic rebound. However, the earth obviously is brittle unlike the sponge! \n\nThe sensisitivity of the instruments used in detecting earthquakes is the reason for most of the 'increased' activity in the last century.\n\nIn other words, nature is far more powerful than the average perosn who has not studied the earths process in detail can imagine!

As the tectonic plates move, their boundaries crush against each other and create pressure.  Eventually, the pressure will build up to a point where it overcomes the friction holding two sections of rock together.  The sections will slip. relieving the pressure and creating an earthquake as the energy that was held in the two sections is transferred into seismic waves, also known as an earthquake.

That is a very tricky question, I am doing my undergraduate thesis on this topic in comparing the 1995 NBC with the more current 2005 edition.  The loading for which you design must be specified by your countries or provinces building code.  Because wind speed varies all the time and earthquakes come in all different magnitudes, a reasonable value for each must be used in the desing of the lateral supports for the building.  Generally a statistical anaylsis will determine the design wind force or quake strength.  The find speed can be converted to a pressure using the density of air and must be considered on the windward and leeward sides of a building.  It increases with height.  Earthquake loading is much trickier since the ground is shaking but generally triangular loading is used with the most force at the top and the least at the bottom.  the 95 code also specifies a concentrated force at the roof

An earthquake is the shaking of the ground caused by an abrupt shift of rock along a fracture in the Earth, called a fault. Within seconds, an earthquake releases stress that has slowly accumulated within the rock, sometimes over hundreds of years. ... \nThe size of an earthquake is indicated by a number called its magnitude. Magnitude is calculated from a measurement of either the amplitude or the duration of specific types of recorded seismic waves. Magnitude is determined from measurements made from seismograms and not on reports of shaking or interpretations of building damage. ... The intensity of and earthquake is a measure of the amount of ground shaking at a particular site, and it is determined from reports of human reaction to shaking, damage done to structures, and other effects. ... \n\nEarth scientists believe that most earthquakes are caused by slow movements inside the Earth that push against the Earth's brittle, relatively thin outer layer, causing the rocks to break suddenly. This outer layer is fragmented into a number of pieces, called plates. Most earthquakes occur at the boundaries of these plates. In Washington State, the small Juan de Fuca plate off the coast of Washington, Oregon, and northern California is slowly moving eastward beneath a much larger plate that includes both the North American continent the land beneath part of the Atlantic Ocean. Plate motions in the Pacific Northwest result in shallow earthquakes widely distributed over Washington and deep earthquakes in the western parts of Washington and Oregon. The movement of the Juan de Fuca plate beneath the North America plate is in many respects similar to the movements of plates in South America, Mexico, Japan, and Alaska, where the world's largest earthquakes occur. ...

There is no reliable method to predict an earth quake.What scientists do is use mathematical models based on historical information of earth quakes and estimate the probability in different regions.Lasers and satellite based data and evaluations are used by some.

Most earthquakes are causally related to compressional or tensional stresses built up at the margins of the huge moving lithospheric plates that make up the earth's surface (see lithosphere). The immediate cause of most shallow earthquakes is the sudden release of stress along a fault, or fracture in the earth's crust, resulting in movement of the opposing blocks of rock past one another. These movements cause vibrations to pass through and around the earth in wave form, just as ripples are generated when a pebble is dropped into water. Volcanic eruptions, rockfalls, landslides, and explosions can also cause a quake, but most of these are of only local extent. Shock waves from a powerful earthquake can trigger smaller earthquakes in a distant location hundreds of miles away if the geologic conditions are favorable.

I can't tell you a report on it but you'll want to know what type of soil you're dealing with and the bearing strength of the soil.  Clay's are prone to swell when they absorb water which could cause excess stress on a building.  Top soil isn't very suitable for bearing weight.  Ideally if you want the soundest structure you're going to want it's foundation to be in contact with undisturbed rock.  If it's on top of soil in an earthquake it will have problems as a result of liquifaction, whereas if it's load is supported by undisturbed bedrock then it shouldn't sink as a result of liquifaction.\n\nAlso if the soil isn't capable of bearing the weight of the structure there will be excess setteling that could cause a structural failure.
