EARTHQUAKE WAVES\n\nEarthquakes produce three kinds of shock waves.\n\nBody waves move through the Earth from the focus.\n\nSurface waves travel in the outer layers of the Earth.\n\nFree oscillations are the movement of the entire Earth as the result of the largest earthquakes.\n\nBody waves are composed of two types of waves.\n\nP or primary waves are waves where the rock is push back and forth through compression.\n\nS or secondary waves are waves where the rock is pulled sideways.\n\nP and S waves have been used to understand the composition of the interior of the Earth.\n\nThese waves take different tracks and velocities depending on the density and elasticity of the material they are passing through.\n\nS waves do not pass through liquids so the inability of the the outer core to carry S waves would suggest the presence of a liquid core.\n\nAt the Earths surface earthquake waves can sometimes be seen causing the surface to oscillate.\n\nIn oceans the wave energy can be transferred into the water to form tsunami.

Whan an earthquake occurs, it sends shock waves through the earth. One travels through the earth's surface by compressing back and forth the rocks, the other by moving them up and down. These both travel at different but known speeds, so when an earthquake registers at a recording site it registers as two blips, a P wave blip first and an S wave blip later. The distance between these blips tells the seismologists how far away the earthquake was, the bigger the gap, the further the distance. To find the location of the earthquake you then need to use different recording sites data for how far away it was and triangulate the data to find an actual location of the epicentre. The waves also travel through the earth in different ways in addition to the p and the s waves, by going throught the surface or more directly through the earths core. Again the data for these echo times differences is known and allows a distance to the epicentre to be calculated.

Nothing!  Seismic Waves are caused by earthquakes not hurricanes.  A good transmit means certain substance aid wave movement and others hinder wave movement,\nHurricanes cause high wind, spawn tornadoes, cause flooding from heavy rain and tidal surges and usually effect large areas.

Ground shaking leads to landslides and other soil movement. These are the main damage-causing events that occur during an earthquake. Primary effects that can accompany an earthquake include property damage, loss of lives, fire, and tsunami waves. Secondary effects, such as economic loss, disease, and lack of food and clean water, also occur after a large earthquake.\n\nEarthquake waves make the ground move, shaking buildings and causing poorly designed or weak structures to partially or totally collapse. The ground shaking weakens soils and foundation materials under structures and causes dramatic changes in fine-grained soils. During an earthquake, water-saturated sandy soil becomes like liquid mud, an effect called liquefaction. Liquefaction causes damage as the foundation soil beneath structures and buildings weakens. Shaking may also dislodge large earth and rock masses, producing dangerous landslides, mudslides, and rock avalanches that may lead to loss of lives or further property damage.

Seismic waves have many different names based on their different motions and behaviors.  P-waves, S-waves, Surface Waves, Love Waves and Rayleigh Waves.  All behave differently.

A seismograph measures the strength and direction of earthquake waves. It records the tremors and compares their strengths on the Richter scale. A scale of one is a minor earthquake, while a scale of seven is severe.

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. ...

Waves are formed in three ways, gravity, wind and earthquakes. Gravity is responsible for the high and low tides. High tide is when the water is the deepest and low tide is when the water is most shallow. The rise and fall of the water level causes waves to form.\n\nThe second cause of waves is wind. The wind can be light and only cause small waves. These waves can be as tiny as ripples in the water. Young children can practice making waves by blowing on a bowl full of water.\n\nWind can also cause very large waves that make being in the water very dangerous. Even large ships don't want to be caught in a storm with huge waves.\n\nThe type of wave wind causes depends on how hard the wind is blowing, how long the wind blows and how much ocean the wind blows over.\n\nLastly, waves can be caused by earthquakes. Earthquakes are the result of two of the earth's plates rubbing together. Just as we stumble or fall during an earthquake, water also reacts to the power force. The earthquake pushes the water away from the epicenter of the quake and can cause some pretty large waves.

The three types of plate boundaries are: convergent (or destructive, two plates push against one another), divergent (or constructive, two plates move away from each other), and transform (two plates slide past one another)

“Earthquake prediction” in the popular language is consonant with short-term prediction.  Scientists are sure about where earthquakes will occur, and a general time span.  For example, I live in San Francisco, and we know that sometime in the next 30 years, there's going to be a big one.\n\nAt the present time, optimism is rather low about the prospects for short-term prediction, because of its local nature: one would have to be fortunate to have instruments within short range of the future focus of a strong earthquake.\n\nResearch into anomalies in the ratio of P- to S-wave velocities, magnetic fields, resistivity, tilt, emission of noble gases, and so on are no longer at the leading edge of contemporary interest.

An earthquake is a phenomenon that results from and is powered by the sudden release of stored energy in the crust that propagates seismic waves. At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes tsunamis, which may lead to loss of life and destruction of property.\n\nEarthquakes may occur naturally or as a result of human activities. In its most generic sense, the word earthquake is used to describe any seismic event—whether a natural phenomenon or an event caused by humans—that generates seismic waves.\n\nTypes of earthquakes Naturally occurring earthquakes Most naturally occurring earthquakes are related to the tectonic nature of the Earth. Such earthquakes are called tectonic earthquakes. The Earth's lithosphere is a patchwork of plates in slow but constant motion caused by the heat in the Earth's mantle and core. Plate boundaries grind 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 seismic waves are radiated, thus causing an earthquake. This processes of strain, stress, and failure is referred to as the Elastic-rebound theory. It is estimated that only 10 percent or less of an earthquake's total energy is radiated as seismic energy. Most of the earthquake's energy is used to power the earthquake fracture growth and is converted into heat. Therefore, earthquakes lower the Earth's available potential energy, though these losses are negligible 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\nYou could get more information from the link below...

Visit my slide show at URL\nhttp://asia.pg.photos.yahoo.com/ph/quake\nMost of the earthquakes occurs at tectonic plate boundaries.\nThis will occur when the accumulated stress (because of the movement of plates ) exceeds the bearable limit of the tectonic plates at that place.

Go to this web site and read what is there:\n\nhttp://schools.matter.org.uk/Content/Seismology/shadow_zone.html\n\nBasically, there are two kinds of seismic waves from an earthquake or an underground nuclear explosion. These are called P waves and S waves. The S waves cannot travel through the liquid rock surrounding the earth's solid core, so this core creates a "shadow" for those waves. A different kind of "shadow" is created for P waves as they refract at the liquid/solid interface.\n\nHope this helps. Fascinating stuff seismography!

In the sense of an earthquake, yeah.  That's what it is.  A wave of earth moving out from the central point of origin.  That has nothing to do with the wave-particle duality.  In fact, it's best not to think of it as an actual wave or an actual particle (like a billiard ball).

the beginning of an earthquake are foreshocks. these foreshocks have P-waves, s-waves and surface waves attached to it.
