Earthquakes suggest new tectonic plate is forming
CBS News/ ^ | September 27, 2012, 2:02 PM | By Bailey Johnson /

A new study suggests that two recent earthquakes may indicate a literal seismic shift in our understanding of tectonic plate movements.

Massive earthquakes under the Indian Ocean that took place last spring are the largest of their kind ever recorded. The 8.7 magnitude quake, followed by a 8.2 magnitude aftershock, could signal the formation of a new plate boundary under the Earth.

While not the largest earthquakes ever recorded, the two quakes are notable for their unusual location. The majority of earthquakes are known as thrust faults: massive sheets of rock sliding over or under another block along a fault line. The two earthquakes recorded in April were strike-slip faults, where one block of rock slides alongside another. The April quakes, which took place off the coast of Indonesia, are the largest slip-strike faults ever observed.

Additionally, the two earthquakes took place within a plate, rather than on its edge. According to a study published in the journal Nature, the quakes were part of the breakup of the Indian and Australian subplates under the Indian Ocean. The study also increased the magnitude of the initial earthquake to 8.7 - a significant increase in power as the Richter scale which is used to gauge the magnitude of earthquakes increases logarithmically rather than linearly.

Researchers believe the earthquakes were the result of the Indo-Australian plate rending itself apart. Seismologists have suspected the plate might be breaking apart since the 1980's. But the April earthquakes are the clearest evidence yet of this phenomenon. As one scientist wrote, "The long-term scenario is that a nascent plate tectonic boundary is forming: the Australian plate is becoming detached from the Indian plate."

This detachment will take several million years to complete, but research suggests more earthquakes like the ones in April will become increasingly likely in the future.

Obviously this is caused by global warming. Heat expands and as the world heats, the crust is expanding and cracking. It may also be due to over-population of the West. As the population in the Western Hemisphere grows, it is increasing the weight on that hemisphere pulling it away from the Eastern Hemisphere, causing more cracks. Also, don’t discount how much this is Bush’s fault. Bush’s big oil buddies keep drilling into the crust of Mother Gaia, causing weak points that create cracks.

Those occurred along a very old fault line. About 600 million years old. It's categorized as a "failed rift".

[...and still counting until 2014]

"this trend needs to be understood in relation to the increase in seismographs. Certainly, in the last 25 years, more lower intensity earthquakes have been noticed because of a general increase in the number of seismograph stations across the world and improved global communications. This increase has helped seismological centres to locate many small earthquakes which were undetected in earlier decades. Therefore, an upward trend is not unexpected in the graph, although the rise in the number of large earthquakes will be of more significance to our assessment of the trend.

By limiting the range of earthquakes being counted in this report to magnitude 7 or above, it means these earthquakes can easily be identified by a limited number of seismographs, and we have ensured that any increase in frequency for these larger earthquakes cannot be down to the increase in overall detection rates in this 25-year period, as all these larger earthquakes are able to be easily detected with fewer seismograph stations."

No, I think you've got that wrong. The East easily outpopulates the West. The problem is the weight of all the gold, oil, silver and other Third World riches Westerners have stolen from their "rightful owners" (even though they were paid for). The weight of that terrible wealth imbalance is the cause of Global Warming and tectonic plate disruption. It can only be cured by redistributing all American wealth back the the world's corrupt and tribal $hitholes.

“Earthquakes suggest new tectonic plate is forming”

It’s more like an existing plate is being divided into 2. It’s actually the creation of 2 new plates.

Re: rifts and failed rifts....

“In geology, a rift or chasm is a place where the Earth’s crust and lithosphere are being pulled apart[1] and is an example of extensional tectonics.[2]

Typical rift features are a central linear downfaulted segment, called a graben, with parallel normal faulting and rift-flank uplifts on either side forming a rift valley, where the rift remains above sea level. The axis of the rift area commonly contains volcanic rocks, and active volcanism is a part of many, but not all active rift systems.

Major rifts occur along the central axis of mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates.

Failed rifts are where continental rifting began, but then failed to continue to the point of break-up. Typically the transition from rifting to spreading develops at a triple junction where three converging rifts meet over a hotspot. Two of these evolve to the point of seafloor spreading, while the third ultimately fails, becoming an aulacogen.”

http://en.wikipedia.org/wiki/Rift
_________________________________________

“The New Madrid Seismic Zone is made up of reactivated faults that formed when what is now North America began to split or rift apart during the breakup of the supercontinent Rodinia in the Neoproterozoic Era (about 750 million years ago). Faults were created along the rift and igneous rocks formed from magma that was being pushed towards the surface. The resulting rift system failed but has remained as an aulacogen (a scar or zone of weakness) deep underground. Another unsuccessful attempt at rifting 200 million years ago created additional faults, which made the area weaker. The resulting geological structures make up the Reelfoot Rift, and have since been deeply buried by younger sediments. But the ancient faults appear to have made the rocks deep in the Earth’s crust in the New Madrid area mechanically weaker than much of the rest of North America.”

Initial plate or continental rifting was thought to occur in a 3-prong manner (“Y” pattern). So there may be more rifting to come (2 other rift arms). Maybe in a few thousand years or so. Who knows. Not I.

From the article:
“Researchers believe the earthquakes were the result of the Indo-Australian plate rending itself apart. Seismologists have suspected the plate might be breaking apart since the 1980’s. But the April earthquakes are the clearest evidence yet of this phenomenon. As one scientist wrote, “The long-term scenario is that a nascent plate tectonic boundary is forming: the Australian plate is becoming detached from the Indian plate.”...”

I think your table has been flavored with some secret sauce for whatever reasons. I've looked through the USGS data and elsewhere for about the last hour or so and I don't find anything to support the chart's claims. The USGS CENTENNIAL CATALOG has a couple of charts that show only slight variations in major earthquakes since 1900 with the occasional outliers. I'd post the charts but they're in a PDF document; FWIW...

I’m always a bit amused by those who appeal to statistical error, claiming the reduced numbers of >7.0 earthquakes in prior decades/centuries were due partly to the recent numerical increase in seismometers.

It is academia at its most ignorant failure to identify their statistics with the things being measured.

If we accepted that logic, then people in remote regions just didn’t have the resources to perceive >7.0 earthquakes, or perhaps forgot about them. Such an absurd notion disproves their assertions prima facie.

Perhaps in very remote regions where nobody ventured within a 1000 miles or traversed the vicinity, and neither were there geologists to have looked at geologic records, some might have been missed,...but even then that is based upon conjecture as well.

Just looking for some honest debate given the best information at our disposal. The Centennial Catalog, particularly two charts included therin, is the best data I could find to base a discussion on and you STILL haven't commented on it. It's frustrating but it may just be my fault. My patience wears thin at times and I apologize for any sourness in my disposition.

From a layman's point of view much of "science" appears to be nothing more than conjecture. In this particular instance I'll accept the notion that the USGS' recorded and assimilated historical earthquake data is more or less accurate. I can't imagine there would be an agenda at work to prompt them to skew the data. AND, the data shows ups and downs in earthquake magnitude and frequency as far back as they have been able to measure but otherwise remarkably consistent on average.

That's OK, FRiend. I try to rely on accurate data on everything I post here . And my source, as well as yours, did say it was based on USGS data. Precious little info on any of these official government websites is presented in a straight forward, easy to read and understand fashion, even when the info is intended for the public (government seems to always have their heads up their butts when it comes to communicating). However, I do now see the chart you posted on that USGS link you provided (Centennial report, page 6 on the pdf).

I also found the following which similarly supports what you said:

"We continue to be asked by many people throughout the world if earthquakes are on the increase. Although it may seem that we are having more earthquakes, earthquakes of magnitude 7.0 or greater have remained fairly constant."

http://earthquake.usgs.gov/learn/topics/increase_in_earthquakes.php

In any case, I was really (initially) referring to what seems to me to be an increase in large quake activity in and around the Indonesia area over the past few decades. I kind of mixed up the two two things with that chart on activity worldwide.

The great Lisbon earthquake hundreds of years ago, the New Madrid quakes of 1811 to 12, a huge quake in Assam in the 1950s if I remember correctly. I guess the “later days” are turning into the later centuries.
