Can “Mega Quakes” really happen?
THEORETICALLY, YES. REALISTICALLY, NO. The magnitude of an earthquake is related to the length of the fault on which it occurs -- the longer the fault, the larger the earthquake. The San Andreas Fault is only 800 miles long. To generate an earthquake of 10.5 magnitude would require the rupture of a fault that is many times the length of the San Andreas Fault. No fault long enough to generate a magnitude 10.5 earthquake is known to exist. The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles long. The magnitude scale is open-ended, meaning that science has not put a limit on how strong an earthquake could be, and scientists can’t rule out a “Mega Quake” because they’ve only been measuring earthquakes for 100 years, a blink of an eye in geologic time. However, scientists agree that “Mega Quakes” of magnitude 10 or more are implausible.

You do know how USGS get's it's data don't you?
So you argue with facts by declaring them all part of a giant government conspiracy? I enjoy your post however there is a point when the data becomes so overwhelmingly convincing that you should capitulate and admit that perhaps what you posted was not the accumulation of all the facts.
I gotta go eat now but thanks for the lively debate
I'll even give you a flag which I hardly ever do for anyone.

You claim earthquakes are on the rise and I show you the data to disprove you yet you claim the data is false. Very well, now show me your data that supports your claims so I may evaluate that.edit on 27-6-2011 by kro32 because: (no reason given)

History channel is entertainment and if you don't know that i'm surprised. As far as fossils at mountaintops that is not due to violent mega earthquakes but slow uplift of land. I live at almost 8000 ft. and this area used to be tropical. It did not happen overnight.
I would be happy to list some beginning geology books for you if your really interested in this stuff..It's quite fascinating.

So now you are a geology expert as well? If so please share your weath of knowledge with me becasue I'm always eager to study this planet and the myriad of changes it's went through since it came into exsistence. I'm being serious by the way, not sarcastic.
"A magnitude 7.6 earthquake could cause seafloor uplift of six feet or more," Borrero said. "That, in turn, would disturb the sea surface by the same amount, resulting in a tsunami. The shallow San Pedro shelf offshore of Long Beach focuses the waves and amplifies them by one-and-a -half times, so the original six-foot wave would build to nine feet inside the harbor."
Sure it is look at the title of the thread. It's puposefully written to invoke fear and panic

The folks at prophecies.us are saying 2 mega quakes will occur very soon in California (within the year). The general consensus is that it will be 2 large quakes occurring within a short time period of one another, the latter quake being much larger than the other, a gigantic tsunami, an orange bridge will collapse (possibly the golden gate), both quakes will occur during cooler weather, and California will crumble into the ocean along with a portion of Nevada during the latter of the quakes. They are going bonkers about it right now.
Another surprising result concerned the San Jacinto Fault, a lesser known Southern California fault yet one of the most significant branches of the San Andreas system. Fialko's analysis of the San Jacinto Fault, which winds through populated areas in San Bernardino, Riverside and Borrego Springs, found that it is moving at roughly twice the speed of previous estimates and thereby its propensity for earthquakes is greatly enhanced. While the San Andreas is at risk for an earthquake of magnitude eight or higher, the San Jacinto Fault has an even greater risk for a slightly smaller earthquake of magnitude seven, which still falls into the category of a major earthquake.
