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.

Wave motion is defined as the movement of a distortion of a material or medium, where the individual parts or elements of the material only move back-and-forth, up-and-down, or in a cyclical pattern.\n\nIt appears as if something is actually moving along the material, but in reality it is just the distortion moving, where one part influences the next.

It depends on what you define as an earthquake. A large earthquake that excites the earth's free oscillations will produce detectable ringing for many hours.

The term "tsunami" is the proper name for what is commonly referred to as a tidal wave. The term tidal wave is technically incorrect since it is not a wave caused by the tides. Rather, tsunamis are caused by seismic activities in and near the ocean, such as earthquakes or volcanic eruptions.

It is a longitudinal wave\nit is nothing but energy travelling from the point of disturbance outwards in all directions.

Yes and no!\n\nYes - the amount of energy released when the fault slips dictates the force of the shock waves.\n\nBut the No is also important.   A deep high magnitude earthquake may not rattle a cup because most of it's energy is absorbed before it reaches the surface.  Where a relatively much lighter earthquake on the surface could cause devesatation.

yea.. it's Helicorder Images, a way to record the earthquake in a given area.. even it is minimum. for reading of this, you need to do a bit study. surf the net, also go here:

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

An aftershock is a small earthquake that happens just after a big one.

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\n\nNaturally occurring earthquakes :-\nMost naturally occurring earthquakes are related to the tectonic nature of the Earth.

In subduction zones, where older and colder oceanic crust descends beneath another tectonic plate, earthquakes may occur at much greater depths (up to hundreds of kilometers). These seismically active areas of subduction are known as Wadati-Benioff zones. Deep focus earthquakes are another phenomenon associated with a subducting slab. These are earthquakes that occur at a depth at which the subducted lithosphere should no longer be brittle, due to the high temperature and pressure. A possible mechanism for the generation of deep focus earthquakes is faulting caused by olivine undergoing a phase transition into a spinel structure.\nEarthquakes may also occur in volcanic regions and are caused by the movement of magma in volcanoes.

A series of waves that were displaced on a mega huge scale generally caused by earthquakes or meteor impact. Tsunami is Japanese for harbor wave, due to the fact that tsunamis are not tidal waves but have a much smaller crest therefore goes, for the most part visually unnoticed. As far as the effects we saw that one of the islands that were devastated during the last major one in Asia was moved 100 feet? beyond where it was originally located and according to NASA actually disrupted the rotation of the earth.

Definition of tsunami: An ocean wave produced by a sub-marine earthquake, landslide, or volcanic eruption. These waves may reach enormous dimensions and have sufficient energy to travel across entire oceans.\n\nThe first link below is a site dedicated to tsunamis. Check it out.

The most typical example of this kind of waves are the sound waves, propagating in any medium. If no sound the density of medium d=constant through out the whole volume. If sound then d1=d+delta means compression, d2=d-delta rarefaction. If d1 & d2 alternate along the path of the wave with certain period we can describe it in terms of sine/cosine, delta being its amplitude. The alternation of d1/d2 occurs because of inertia of medium molecules.

Huracaine is a cyclic movement of the air caused by a depression in the atmosphere, usually it picks up speed on water and slows down as it gets inland. A tsunami is a tidal wave caused by an earth quake. Usually the epicenter of the earth quake is in the middle of the ocean, but there have been cases where the epicenter was along the coast and it still caused giant waves to come crashing.

1) all three can happen, but most 'common', or at the most angles, the answer is refracted.\n\n2) b.  The example I usually give is shaking a slinky back and forth.\n\n3) mohorviric discontinuity, or moho for short.  It's about 6 km for ocean crust, and 30 km for continental crust.\n\n4) d for sure!

Lots of people call tsunamis tidal waves. After seeing pictures of the recent tsunami in south Asia, I can see why. They really do look more like a giant high tide than a giant high wave.
