what is the New Madrid Fault line?
485592
The New Madrid Fault Line (aka New Madrid Seismic Zone, Reelfoot Rift)  is a 150 mile fault stretching from Cairo, Illinois (which is right on the state border with Kentucky) to Marked Tree, Arkansas.\n\nThere were some 7.0+ magnitude earthquakes from this fault in a 3-month period of 1811-12, causing the Mississippi River to flow backward and change its course.  The largest was called the New Madrid Earthquake and happened on Feb. 7, 1812 with 7.9 magnitude earthquake and epicenter near New Madrid, Missouri.  There have been numerous 5.0+ from this fault and it is seen as becoming more active.\n\nResearchers currently project a 90% chance of a 6.0 magnitude or greater earthquake by the year 2040.

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 foci of earthquakes at transform boundaries tend to be at shallow depths.\n\nSee source.

The fault zone itself has no epicenter. It runs from the Gulf of Mexico to an area approximately 50 miles north of San Francisco in the Pacific Ocean. An earthquake that is triggered anywhere along the fault is what is concidered to be the epicenter.

It won't be Arizona, my friend. When San Andreas cracks open, and it will, the coast line will be on the Western Slope of Colorado, and I'll tell you why!!\nIn the middle of the Mojave Desert is a Nuclear testing plant, placed there by our wonderful United States Government (what a bunch of pricks). When the big one hits...say goodbye to about 1,000 miles of these United States (and parts of Mexico, too).

Yes. \n\nThe earthquake starts when the two massive land masses on each side of the fault line break loose, as the Masses are trying to move and build up tremendous pressure in the fault (The actual crack between land Masses) builds and finally releases when the land Masses suddenly jolt apart causing an oscillation  resulting in an earthquake. \n\nGood question, \n\nDarryl S.

The USGS has diagrams of earthquake faults and what they look like during a quake.\n\nThe National Park Service has a good map of the various plates that make up the Earth's crust.

Has no one ever heard of "Google.com"? \nType in "geology map lamar county texas" and I'm sure you'll have what you need.

This is an interesting question because there has been recent evidence found using geodetic surveys in southern and central Lousiana that that area is still falling as a possible result of rebound from the Wisconsin glaciation. \n\nI found a good map of geodetic measurements at Northwestern University.  It shows current measured rates of rebound in New England and Canada. It looks like New England is along the pivot line, with the coastal parts still falliing and inland areas rising. The rates are hard to read from the map but appear to be a few mm/year. \nhttp://www.earth.northwestern.edu/research/geodesy.html\n\nI'm also including some links related to the topic that I ran across while trying to find this map.

Geologic faults or simply faults are planar rock fractures which show evidence of relative movement. Large faults within the Earth's crust are the result of shear motion and active fault zones are the causal locations of most earthquakes. Earthquakes are caused by energy release during rapid slippage along faults. The largest examples are at tectonic plate boundaries, but many faults occur far from active plate boundaries. Since faults usually do not consist of a single, clean fracture, the term fault zone is used when referring to the zone of complex deformation associated with the fault plane.\n\nThe two sides of a fault are called the hanging wall and footwall. By definition, the hanging wall occurs above the fault and the footwall occurs below the fault.\n\n\nStrike-slip faults\nThe fault surface is usually near vertical and the footwall moves either left or right or laterally with very small vertical motion. Strike-slip faults with left-lateral motion are also known as sinistral faults. Those with right-lateral motion are also known as dextral faults. A special class of strike-slip faults is the transform faults which are a plate tectonics feature related to spreading centers such as mid-ocean ridges.\n\n(i wish i could type the photo i have as well)

Because San Fran is on a major fault line. That basically means that the ground below the streets isn't set properly so it fragments easily to make the Earth subside, and the Earthquakes to occur. I don't know why its like it in the 1st place though?

Composite cone volcanoes are often found near convergent plate boundaries. And at all fault lines there are earthquakes so yes, there is.

The Earth is formed of several layers that have very different physical and chemical properties. The outer layer, which averages about 70 kilometers in thickness, consists of about a dozen large, irregularly shaped plates that slide over, under and past each other on top of the partly molten inner layer. Most earthquakes occur at the boundaries where the plates meet. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. \nThere are three types of plate boundaries: spreading zones, transform faults, and subduction zones. At spreading zones, molten rock rises, pushing two plates apart and adding new material at their edges. Most spreading zones are found in oceans; for example, the North American and Eurasian plates are spreading apart along the mid-Atlantic ridge. Spreading zones usually have earthquakes at shallow depths (within 30 kilometers of the surface).  \n\nTransform faults are found where plates slide past one another. An example of a transform-fault plate boundary is the San Andreas fault, along the coast of California and northwestern Mexico. Earthquakes at transform faults tend to occur at shallow depths and form fairly straight linear patterns. \n\nSubduction zones are found where one plate overrides, or subducts, another, pushing it downward into the mantle where it melts. An example of a subduction-zone plate boundary is found along the northwest coast of the United States, western Canada, and southern Alaska and the Aleutian Islands. Subduction zones are characterized by deep-ocean trenches, shallow to deep earthquakes, and mountain ranges containing active volcanoes.\n\nEarthquakes can also occur within plates, although plate-boundary earthquakes are much more common. Less than 10 percent of all earthquakes occur within plate interiors. As plates continue to move and plate boundaries change over geologic time, weakened boundary regions become part of the interiors of the plates. These zones of weakness within the continents can cause earthquakes in response to stresses that originate at the edges of the plate or in the deeper crust. The New Madrid earthquakes of 1811-1812 and the 1886 Charleston earthquake occurred within the North American plate.
