An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 In Geology, a crust is the outermost solid shell of a planet or moon Seismic waves are Waves that travel through the Earth, most often as the result of a tectonic Earthquake, sometimes from an Explosion Earthquakes are recorded with a seismometer, also known as a seismograph. Seismometers (from Greek Seism - "the shakes" - and Metro - "I measure" are instruments that measure and record motions of the ground including The moment magnitude of an earthquake is conventionally reported, or the related and mostly obsolete Richter magnitude, with magnitude 3 or lower earthquakes being mostly imperceptible and magnitude 7 causing serious damage over large areas. TalkMoment magnitude scale#Real world examples please.--> The moment magnitude scale The Richter magnitude scale, or more correctly local magnitude M L scale assigns a single number to quantify the amount of seismic energy released Intensity of shaking is measured on the modified Mercalli scale. The Mercalli intensity scale is a scale used for measuring the intensity of an Earthquake.
At the Earth's surface, earthquakes manifest themselves by a shaking and sometimes displacement of the ground. When a large earthquake epicenter is located offshore, the seabed sometimes suffers sufficient displacement to cause a tsunami. The epicenter or epicentre is the point on the Earth 's surface that is directly above the Hypocenter or focus the point where an Earthquake A tsunami ((tsuːˈnɑːmi is a series of waves created when The shaking in earthquakes can also trigger landslides and occasionally volcanic activity.
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. A phenomenon (from Greek φαινόμενoν, pl φαινόμενα - phenomena) is any observable occurrence Seismic waves are Waves that travel through the Earth, most often as the result of a tectonic Earthquake, sometimes from an Explosion Earthquakes are caused mostly by rupture of geological faults, huge amounts of gas migration, mainly methane deep within the earth, but also by volcanic activity, landslides, mine blasts, and nuclear experiments.
An earthquake's point of initial rupture is called its focus or hypocenter. The hypocenter or hypocentre (literally 'below the center' from the Greek υπόκεντρον) refers to the site of an earthquake or to that of a nuclear The hypocenter or hypocentre (literally 'below the center' from the Greek υπόκεντρον) refers to the site of an earthquake or to that of a nuclear The term epicenter means the point at ground level directly above this. The epicenter or epicentre is the point on the Earth 's surface that is directly above the Hypocenter or focus the point where an Earthquake

Naturally occurring earthquakes
Fault types
Tectonic earthquakes will occur anywhere within the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane. The epicenter or epicentre is the point on the Earth 's surface that is directly above the Hypocenter or focus the point where an Earthquake In Geology a fault, or fault line, is a planar rock fracture which shows evidence of relative movement In the case of transform or convergent type plate boundaries, which form the largest fault surfaces on earth, they will move past each other smoothly and aseismically only if there are no irregularities or asperities along the boundary that increase the frictional resistance. A transform fault is a fault which runs along the boundary of a Tectonic plate. In Plate tectonics, a convergent boundary – also known as a convergent plate boundary or a destructive plate boundary – is an actively deforming region Geology, aseismic creep is measurable surface displacement along a fault in the absence of notable Earthquakes An example is along the Calaveras Most boundaries do have such asperities and this leads to a form of stick-slip behaviour. Stick-slip (or "slip-stick" refers to the phenomenon of a spontaneous jerking motion that can occur while two objects are sliding over each other Once the boundary has locked, continued relative motion between the plates leads to increasing stress and therefore, stored strain energy in the volume around the fault surface. This continues until the stress has risen sufficiently to break through the asperity, suddenly allowing sliding over the locked portion of the fault, releasing the stored energy. This energy is released as a combination of radiated elastic strain seismic waves, frictional heating of the fault surface, and cracking of the rock, thus causing an earthquake. Seismic waves are Waves that travel through the Earth, most often as the result of a tectonic Earthquake, sometimes from an Explosion This process of gradual build-up of strain and stress punctuated by occasional sudden earthquake failure is referred to as the Elastic-rebound theory. The elastic rebound theory is an explanation for how energy is spread during earthquakes 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 or is converted into heat generated by friction. A fracture is any local separation or discontinuity plane in a Geologic formation, such as a joint or a fault that divides the rock into two or more Therefore, earthquakes lower the Earth's available elastic potential energy and raise its temperature, though these changes are negligible compared to the conductive and convective flow of heat out from the Earth's deep interior. [1]
Earthquakes away from plate boundaries
Where plate boundaries occur within continental lithosphere, deformation is spread out a over a much larger area than the plate boundary itself. In the case of the San Andreas fault continental transform, many earthquakes occur away from the plate boundary and are related to strains developed within the broader zone of deformation caused by major irregularities in the fault trace (e. The San Andreas Fault is a geologic Transform fault that runs a length of roughly 800 miles (1300 km through California in the United States. g. the “Big bend” region). The Northridge earthquake was associated with movement on a blind thrust within such a zone. Another example is the strongly oblique convergent plate boundary between the Arabian and Eurasian plates where it runs through the northwestern part of the Zagros mountains. The Arabian Plate is one of three Tectonic plates (the African Arabian and Indian crustal plates) which have been moving northward over millions of The Eurasian Plate is a Tectonic plate which includes most of the continent of Eurasia (a landmass consisting of the traditional Continents of Europe The Zagros Mountains (جبال زاجروس (رشته كوههاى زاگرس ( Sorani Kurdish: Zagros - زاگرۆس make up Iran 's and Iraq 's The deformation associated with this plate boundary is partitioned into nearly pure thrust sense movements perpendicular to the boundary over a wide zone to the southwest and nearly pure strike-slip motion along the Main Recent Fault close to the actual plate boundary itself. This is demonstrated by earthquake focal mechanisms. The focal mechanism of an Earthquake describes the inelastic deformation in the source region that generates the seismic waves [2]
All tectonic plates have internal stress fields caused by their interactions with neighbouring plates and sedimentary loading or unloading (e. g. deglaciation). These stresses may be sufficient to cause failure along existing fault planes, giving rise to intra-plate earthquakes.
Deep focus earthquakes
The majority of tectonic earthquakes originate at depths not exceeding tens of kilometers. In subduction zones, where older and colder oceanic crust descends beneath another tectonic plate, Deep focus earthquakes may occur at much greater depths (up to seven hundred kilometers). In Geology, a subduction zone is an area on Earth where two tectonic plates meet and move towards one another with one sliding underneath the other Oceanic crust is the part of Earth's Lithosphere that surfaces in the Ocean basins A deep-focus earthquake is an Earthquake that occurs at depths between 300 and 700 km beneath the Earth's surface These seismically active areas of subduction are known as Wadati-Benioff zones. A Wadati-Benioff zone (also Benioff-Wadati zone or Benioff zone) is a deep active seismic area in a Subduction zone 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. The lithosphere (IPA, from the Greek λίθος for "rocky" + σφαίρα for "sphere" is the solid outermost shell of a rocky Planet. A possible mechanism for the generation of deep focus earthquakes is faulting caused by olivine undergoing a phase transition into a spinel structure. The Mineral olivine (when gem-quality also called Peridot) is a Magnesium Iron silicate with the formula ( Mg In Thermodynamics, phase transition or phase change is the transformation of a thermodynamic system from one phase to another The spinels are any of a class of Minerals of general formulation XY2 O 4 which Crystallize in the cubic (isometric [3]
Earthquakes and volcanic activity
Earthquakes also often occur in volcanic regions and are caused there, both by tectonic faults and by the movement of magma in volcanoes. Magma (Plurals magmas and magmata) is molten rock that sometimes forms beneath the surface of the Earth (or any other Terrestrial planet Plate tectonics and hotspots Divergent plate boundaries At the Such earthquakes can serve as an early warning of volcanic eruptions.
Earthquake storms
Sometimes a series of earthquakes occur in a sort of earthquake storm, where the earthquakes strike a fault in clusters, each triggered by the shaking or stress redistribution of the previous earthquakes. An earthquake storm is a recently proposed theory about Earthquakes where one triggers a series of other large earthquakes&mdashwithin the same Tectonic plate &mdashas Similar to aftershocks but on adjacent segments of fault, these storms occur over the course of years, and with some of the later earthquakes as damaging as the early ones. An aftershock is an Earthquake that occurs after a previous earthquake (the main shock Such a pattern was observed in the sequence of about a dozen earthquakes that struck the North 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. The North Anatolian Fault (NAF ( Kuzey Anadolu Fay Hattı is a major active right lateral-moving Geologic fault in northern Anatolia which runs along the Tectonic New Madrid (nuːˈmædrɪd is a city in New Madrid County, Missouri, 42 miles (68 km south by west of Cairo Illinois, on the Mississippi River
Size and frequency of occurrence
Minor earthquakes occur nearly constantly around the world in places like California and Alaska in the U. California ( is a US state on the West Coast of the United States, along the Pacific Ocean. Alaska ( Аляска Alyaska) is a state in the United States of America, in the northwest of the North American continent S. , as well as in Chile, Peru, Indonesia, Iran, Pakistan the Azores in Portugal, Turkey, New Zealand, Greece, Italy, and Japan,[4] Larger earthquakes occur less frequently, the relationship being exponential; for example, roughly ten times as many earthquakes larger than magnitude 4 occur in a particular time period than earthquakes larger than magnitude 5. Chile, officially the Republic of Chile ( Spanish:) is a country in South America occupying a long and narrow Coastal strip wedged between the Peru (Perú Piruw Piruw officially the Republic of Peru ( reˈpuβlika del peˈɾu is a country in western South America.

In Seismology, the Gutenberg–Richter law expresses the relationship between the magnitude and total number of Earthquakes in any given region and time In the (low seismicity) United Kingdom, for example, it has been calculated that the average recurrences are:
- an earthquake of 3. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located 7 - 4. 6 every year
- an earthquake of 4. 7 - 5. 5 every 10 years
- an earthquake of 5. 6 or larger every 100 years.
The number of seismic stations has increased from about 350 in 1931 to many thousands today. As a result, many more earthquakes are reported than in the past because of the vast improvement in instrumentation (not because the number of earthquakes has increased). The USGS estimates that, since 1900, there have been an average of 18 major earthquakes (magnitude 7. The United States Geological Survey ( USGS) is a scientific agency of the United States government. 0-7. 9) and one great earthquake (magnitude 8. 0 or greater) per year, and that this average has been relatively stable. [5] In fact, in recent years, the number of major earthquakes per year has actually decreased, although this is likely a statistical fluctuation. More detailed statistics on the size and frequency of earthquakes is available from the USGS. [6]
Most of the world's earthquakes (90%, and 81% of the largest) take place in the 40,000-km-long, horseshoe-shaped zone called the circum-Pacific seismic belt, also known as the Pacific Ring of Fire, which for the most part bounds the Pacific Plate. The Pacific Plate is an oceanic Tectonic plate beneath the Pacific Ocean. [7][8] Massive earthquakes tend to occur along other plate boundaries, too, such as along the Himalayan Mountains. Humans can cause earthquakes for example by constructing large dams and buildings, drilling and injecting liquid into wells, and by coal mining and oil drilling. A dam is a barrier that divides waters. Dams generally serve the primary purpose of retaining water while other structures such as Floodgates, Levees In Architecture, Construction, Engineering and real estate development the word building may refer to one of the following Any man-made Coal mining is the extraction or removal of Coal from the Earth by Mining.

With the rapid growth of mega-cities such as Mexico City, Tokyo or Tehran, in areas of high seismic risk, some seismologists are warning that a single quake may claim the lives of up to 3 million people. A megacity is generally defined as a Metropolitan area with a total Population in excess of 10 million people Mexico City (in Spanish: Ciudad de México, México DF, México or simply Méjico) is the Capital city of Mexico officially, is one of the 47 prefectures of Japan and located on the eastern side of the main island Honshū.

There are many effects of earthquakes including, but not limited to the following:
Shaking and ground rupture
Shaking and ground rupture are the main effects created by earthquakes, principally resulting in more or less severe damage to buildings or other rigid structures. The severity of the local effects depends on the complex combination of the earthquake magnitude, the distance from epicenter, and the local geological and geomorphological conditions, which may amplify or reduce wave propagation. The Richter magnitude scale, or more correctly local magnitude M L scale assigns a single number to quantify the amount of seismic energy released The epicenter or epicentre is the point on the Earth 's surface that is directly above the Hypocenter or focus the point where an Earthquake Wave propagation is any of the ways in which waves travel through a Waveguide. The ground-shaking is measured by ground acceleration.
Specific local geological, geomorphological, and geostructural features can induce high levels of shaking on the ground surface even from low-intensity earthquakes. This effect is called site or local amplification. It is principally due to the transfer of the seismic motion from hard deep soils to soft superficial soils and to effects of seismic energy focalization owing to typical geometrical setting of the deposits. Seismology (from Greek grc σεισμός seismos, "earthquake" and grc -λογία -logia) is the scientific study of Earthquakes
Ground rupture is a visible breaking and displacement of the earth's surface along the trace of the fault, which may be of the order of few metres in the case of major earthquakes. Ground rupture is a major risk for large engineering structures such as dams, bridges and nuclear power stations and requires careful mapping of existing faults to identify any likely to break the ground surface within the life of the structure. A dam is a barrier that divides waters. Dams generally serve the primary purpose of retaining water while other structures such as Floodgates, Levees Bridges is the plural form of Bridge. People Bridges is the Family name of Alicia Bridges, Nuclear power is any Nuclear technology designed to extract usable Energy from atomic nuclei via controlled Nuclear reactions
Landslides and avalanches
Earthquakes can cause landslides and avalanches, which may cause damage in hilly and mountainous areas. A landslide is a geological phenomenon which includes a wide range of ground movement such as rock falls deep failure of slopes and shallow debris flows which can occur This article refers to the natural event For other uses see Avalanche (disambiguation An avalanche is an abrupt and rapid flow of snow often
Fires
Following an earthquake, fires can be generated by break of the electrical power or gas lines. Fire is the heat and light energy released during a Chemical reaction, in particular a combustion reaction. Electric power is defined as the rate at which Electrical energy is transferred by an Electric circuit. In the event of water mains rupturing and a loss of pressure, it may also become difficult to stop the spread of a fire once it has started.
Soil liquefaction
Soil liquefaction occurs when, because of the shaking, water-saturated granular material temporarily loses its strength and transforms from a solid to a liquid. Soil liquefaction describes the behavior of loose saturated unconsolidated soils i See also Grain and Film grain Granularity is a measure of the size of the components or descriptions of components that make up A solid' object is in the States of matter characterized by resistance to Deformation and changes of Volume. Liquid is one of the principal States of matter. A liquid is a Fluid that has the particles loose and can freely form a distinct surface at the boundaries of Soil liquefaction may cause rigid structures, as buildings or bridges, to tilt or sink into the liquefied deposits.
Tsunami
Undersea earthquakes and earthquake-triggered landslides into the sea, can cause Tsunami. A tsunami ((tsuːˈnɑːmi is a series of waves created when See, for example, the 2004 Indian Ocean earthquake. The 2004 Indian Ocean earthquake was an undersea Earthquake that occurred at 005853 UTC on December 26 2004 with an Epicentre off the west coast of
Floods
Floods may be a secondary effects of earthquakes, if dams are damaged.
Earthquakes may cause landslips to dam rivers, which then collapse and cause floods.
Human impacts
Earthquakes may result in disease, lack of basic necessities, loss of life, higher insurance premiums, general property damage, road and bridge damage, and collapse of buildings or destabilization of the base of buildings which may lead to collapse in future earthquakes. A disease is an abnormal condition of an organism that impairs bodily functions and can be deadly
The most significant human impact is loss of life
