Do earthquakes follow solar eclipses in the affected regions?

The path of the light (or shadow) is unrelated to the gravity.  Gravity of both bodies (sun and moon) is acting on the whole Earth, not just the area where the eclipse is seen, so earthquakes would not be related to the eclipse.  BTW: Tidal forces of the sun and moon happen all the time and alignments and oppositions will create extreme pulls.

Yeah, like the guy above me said. More elequently, it's not knowing WHERE they are going to go, but WHEN.\n\nIt is virtually impossible to tell exactly when sudden displacement along a fault will occur, although the fact that it will eventually occur can be predicted. This is done by comparing the displacement of regions along the fault that move regularly (and without violent earthquakes) to quiet regions that are not experiencing any little quakes. It's the quiet regions that are to be worried about. They just sit and build up elastic potential and then snap all at once without warning.\n\nRule of thumb, do not live along active fault zones, nor on top of any tsunamite deposits (can be recognized by large angular blocks deposited in a diamicton).

The U.S. is out of luck for this solar eclipse. And by the way...solar eclipses happen during DAYTIME only. Lunar eclipses happen at night.

ok...this is a little complicated. when there is a solar eclipse, only a certain section of the earth can see it because of the angle of light from the sun going around the moon. i cant remember the terminology, but if you look it up on the internet, you could probably find it.

Sorry, but there is no reliable evidence for earthquake lights or any other type of prediction tool.  This is what Dr. Jackson of UCLA told me, a leading geophysist:\n\nEarthquakes follow NO predictable pattern. People have tried and tried, with no luck. They may have accidentally predicted one, but they can not predict anything consistantly.\n\nEarthquakes fall into 3 categories. Some do behave well, they have foreshocks, they show subtle signs, and have aftershocks very nicely. They are still not predictable, but they are closer to being predicted. Some have no warning at all and never show any signs of going. The third group follow no pattern at all, they go seemingly randomly, and they can not even be estimated. It is very hard to tell which fault will be in which group, and this is why prediction is still several breakthroughs away.

the missisippi doesnt normally but it has before. sometime in the early 1900's (i cant remember when) a large earthquake, i think in the mossouri region, actually shifted the earths crust enough for it to run backwards for a short time. this was isolated however and has only happened once in recorded history

San Francisco will not have a total solar eclipse any time in the next 200 years.  There will be an annular eclipse (where the sun's disk is partially covered) on Feb. 18, 2110.  The closest total eclipse to San Francisco will occur on the Central Coast south of San Francisco on May 3, 2106.

the weather does not have any influence on earhquakes.\nEarthquakes are generated by the movements of tectonic plates, by local faults and by volcanic activity.\nCheck these links:\nhttp://earthquake.usgs.gov/\nhttp://volcanoes.usgs.gov/\nhttp://geology.usgs.gov/

Afect in long, medium and short term.\n\nRecent studies shows that earthquakes increase plancton in that specifc area. It warm deep water and increase potenciality of fitoplancton. \n\nInfact is not Tectonic plates but its effects. \n\nOther obvious consequences are volcanoes and montains resultant by tectonic effetc (medium and long term). \n\nAll dorsals (tectonic) have some kind of new categpory of life. They live from minerals, heat and chemicals, entire new ecossitems that are being usedto explain how can be life out of earth. \n\nAt a more long term, you have continent division, creating this way complete new race by geographic isolation. \n\nModern and humans: Tsunamis (changing Human life) like that one last year and  Big one (Economic crisis and Human catastrophic event) - Saint Andreas.

Yes, there are. I have experienced several including the Nisqually Earthquake on 2/28/2001 that registered 6.8 and caused a significant amount of damage. \n\nThe site I added below gives more information about the major faults that are located under the water near the city.

Yes.  There was even one today!  Magnitude 4.8 at a depth of 8.4km in the north east.\n\nCheck out this site:\n\nhttp://www.iris.edu/seismon/\n\n{edit}  Doh!  Someone beat me to it!

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!

Lunar eclipse happen more frequently than solar.(earth has a larger shadow then the moon.)

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

There is no relationship between earthquakes and sunspots.\n\nAn earthquake underneath the ocean can cause tidal waves, as the force is transmitted through the water.

A solar eclipse occurs when the Moon passes in front of the Sun and obscures it totally or partially. This configuration can only occur at New Moon, when the Sun and Moon are in conjunction, as seen from the Earth.\n\nThere are four types of solar eclipses:\n\n1.A total eclipse occurs when the Sun is completely  obscured by the Moon. The intensely bright disk of the Sun is replaced by the dark outline of the Moon, and the much fainter corona is visible (see image right). During any one eclipse, a total eclipse is visible only from a fairly narrow track on the surface of the Earth. \n2.An annular eclipse occurs when the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun. Hence the Sun appears as a very bright ring surrounding the outline of the Moon. \n\n3.A hybrid eclipse is intermediate between a total and annular eclipse. At some points on the Earth it is visible as a total eclipse; whereas at others it is annular. The generic term for a total, annular or hybrid eclipse is a central eclipse. \n\n4.A partial eclipse occurs when the Sun and Moon are not exactly in line, and the Moon only partially obscures the Sun. This phenomenon can usually be seen from a large part of the Earth outside of the track of a central eclipse. However, some eclipses can only be seen as a partial eclipse, because the central line never intersects the Earth's surface.

It isn't "chance" although that is why it is the right/size to produce solar eclipses.\n\nThe moon is not perfectly symmetrical. The crust is thinner on our side, and the core (heavy part of the moon) is displaced towards our side. That acts almost like a handle for the earth's gravity. It has slowed to the point where the earth's gravity now keeps this side pointed towards the earth.\n\nHowever it is not perfect. As seen from the earth, the moon wobbles slightly --- both side to side and up and down. The motion is called libration and allows us to see more than half of the moon. We had a discussion on the yahoo lunar group recently with a link to an animated gif that showed the moon's libration.\n\nIf you are interested in the moon, try\nhttp://groups.yahoo.com/group/lunar-observing/\n\nChuck
