While it is true that SC is considered a passive zone, it does not mean that we don't have earthquakes. Actually SC has a history of earthquakes though most of them are small when compared to those in California. In other words, they don't make the major network news reports. For instance, in February of last year we experienced a 2.9 (RS) quake in Columbia. Most of these small quakes occur in the Piedmont areas. In the last few years there have been several to the west of my location. For more info follow on the earthquake mentioned above follow this link... http://www.dnr.sc.gov/geology/images/Earthquake02-18-05.pdf\n\nAs far as knowing when a major earthquake will occur in SC, that is hard to tell. Earthquake prediction is a tricky business.\n\nThe greatest damage would most likely occur on the coastal plain due to liquefaction. That is where loose unconsolidated sediments/soil when shaken become like a liquid. In the case of a larger quake, this is a hazard not for folks just near the "fault line" but for any area on the coastal plain.\n\nThe link below is a map showing the major faults in SC.\nhttp://www.dnr.sc.gov/geology/images/Fault_Map_Generalized.gif\n\nThis link will take you to the USGS's latest earthquake occurrence map (w/in past 7 days). As you can see the west coast has been busy! http://earthquake.usgs.gov/eqcenter/recenteqsus/\n\nThe link below gives you the southeast's earthquakes in the past 6 months. As you can see, SC hasn't had any recently.\nhttp://folkworm.ceri.memphis.edu/recenteqs/

The structural integridy of the plate itself prevents this. When the earth cooled down after its formation the plates were created like large crystals on the molten surface. They can slowly shift around as a result of the magma currents but to have them break would require a large catastrophic event like a meteor or the earth heating up to levels hot enough to lower their integridy. This of course would be a lethal level and would only occur if, for example, the earth got really close to the sun.\n\nThere is the remote chance that an earthquake at just the right fault line might cause just the right fracture that could move through an entire continent but the probability is very remote.

well city has tons of buildings and the buildings have weight. so they will add more pressure to the tectonic plates and cause them to move faster i guess. There are tectonic plates which meet at one point and they either slip, slide or grind agaisnt each other. and when they slip, this causes the earthquake. so then the more weight on the plates means also more pull. so the plates move faster or something. my guess. but i doubt it has any effect

There are no advantages or disadvantages, it's just a short term weather cycle.  It's like asking what's the advantage to rain?  It you're asking, it doesn't influece global warming or any crap like that.

Hi -\n  Every seismologist on the planet would love to know if they were related!  but earthquakes are a very, very new field of study,  and as yet there is not an awful lot of info on how and why and when,  although I think I can say with reasonable certainty that the moon is most likely not the culprit.  \n  Go to this cool website:  http://earthquake.usgs.gov/eqcenter/recenteqsww/   On it you can see every earthquake in the world in the last seven days within minutes of its happening, as well as learn a TON about the whole field.

You won't be warned.  The earth will just start moving.  The danger isn't the earthquake.  The dangers are the things that fall on you, the fires that burn after (assuming gas lines or electricity or some source of fire and fuel).

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.

people are afraid of earthquakes!

In a nutshell, their is no way to predict earthquakes because there are little to no warnings signs. For example in California, This is a transform fault where two plates are sliding past each other... Eventually the stress builds up so much that it moves a lot at one time.. This is what causes Earth Quakes there, and when they happen they are devastating... We just cant tell when the stress is so much that an earthquake is going to happen.. It is not possible and probably will never be.

Here are the statistics on magnitude of earthquakes, and the number of quakes at each magnitudes, annually.  These records are averages since the year 1900.\n\nGreat, 8 and higher: 1\nMajor,  7 - 7.9:  17\nStrong,  6 - 6.9:  134\nModerate,  5 - 5.9:  1319\nLight,  4 - 4.9:  13,000\nMinor,  3 - 3.9:  130,000\nVery Minor,  2 - 2.9:  1,300,000

i suggest to introduce ur website on different forums,groups etc.\nit is a fine web.\ni experienced the great earthquake which hit northern pakistan on 8th oct.2005.i felt as though i am riding a wild horse.a residential complex fell down in my city and there were 50000 deaths in the area.\n\nhere are some useful links 4 u.\ncheers

Here's an answer that comes from a class I took in structural engineering.  Every building has a natural resonant frequency, ie, a frequency that it tends to oscillate at if it's shaken.  It's just like a tuning fork, or the string of a violin.  If an earthquake shakes the structure at a rate equal to its resonance, it will vibrate much more intensely, and be subject to more damage, that would be the case if the frequency were different. Also, I should point out, there are higher frequencies, called harmonics, which have a similar effect; however, they're not nearly as bad, and can often be ignored.  It has been determined from experience that the very worst earthquakes tend to produce vibrations in the 2 to 4 Hz range, so the engineer designs a building so its natural resonant frequency falls outside this range.  So here's a tip: Find out what frequency the earthquake simulator produces.  Try to design your building so its resonate freq. is higher or lower than that.  You'll have to think a bit about this, and be ingenious!  The frequency can be calculated, but that involves solving some differential equations (I don't think you're ready for that, yet...)

~d1hossain is close.  What you need to check out is "tectonic" plates and tectonic mechanics/physics.   You might also want to look into seismology, volcanism, and diastrophism.  As for the relative danger zones, you might want to look into tsunamis and other seismic displacements.  "Nearness" to a fault is relative in the world of geology.  Few places on earth are not "near" a fault and safe from the effects of a cataclysmic underslide, as evidenced by the Rockies and the Himalayas.\nThat's all of your homework I'll do for you.  If it isn't homework, and you are asking out of genuine curiosity, all the more reason to do your own reasearch.  It's called learning.

the tectonic plates that shift happen  underground, if your lucky to see a plate shift at ground level your truly lucky, these plate shifts cause earthquakes so please be careful.
