Ok, lately Ive been seeing all kinds of unusual and far out theories about the cause of the recent earthquakes in the Indonesian and Pacific regions of the earth. In actual fact, the earthquakes we have been seeing are nothing out of the ordinary. The are not created by HAARP, they are not caused by drought, or anything meteorological, and they are certainly not caused by underground nuclear devices.

The pacific ocean is surrounded on all sides by several tectonic plates. It is approximately 40,000km's in length and influences several continents, which include, Australasia, Asia, North American and South America. This area is known as "The Ring of Fire" (see image below). Movements of these tectonic plates and the movement of rock within smaller fault lines located in these zones.



Before we move on, I will define the different types of movement these plates undergo.

1. Divergence- Two plates moving away from each other

2. Transformation- Two plates slide against each other

3. Subduction (or convergance)- One plate sliding underneath another plate (usually occurs when ocean plates slide under continental or land based plates). Volcanoes are and end result of subduction, as one plate is forced upward creating a peak, or chain of peaks.

4. There is a more complex event, where three plates border one another and cause a mixture of the 3 above principles

Each of the plates located within the ring of fire is undergoing at least one of these processes. The map below shows the direction in which each plate is moving. Its interesting to notice that at points of convergence, there are numerous volcanoes or mountain ranges, caused by millions of years of a plate being forced upwards.



The movements of these plates cause approximately 90% of he worlds earthquakes. So as you can see, earthquakes in these zones are not out of the ordinary, nor is the frequency in which they occur.

90% of the world's earthquakes and 81% of the world's largest earthquakes occur along the Ring of Fire.


This is followed by the following

The next most seismic region (5­6% of earthquakes and 17% of the world's largest earthquakes) is the Alpide belt which extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. The Mid-Atlantic Ridge is the third most prominent earthquake belt.


This map shows the density of earthquake events. Notice the densest areas border the ring of fire



Again, the eathquakes and volcanic activity in the Indonesian area is not unusual. The plate movements in this area go through a process of subduction, where the Indian plate pushes up against the Burma and Sunda plates to the west. This boundary is the outer area of the ring of fire, and is extremely volatile, as massive subduction events often occur.

The boxing day Tsunami in 2004 was result of one of these major subduction movements. It has been proven that there was a movement of 20m over a length of 1600km on the Sunda plate.

More to come on this (prob tomorrow its late here), but until then what is everyones opinion of the above information?

Well except for nuclear underground testing in the pacific....


Nuclear blasts are not allowed to be conducted anymore. In UN countries that is, and other particpants including China. North Korea, Pakistan and Inida are the only countries who havent fully signed on it yet

Are you familair with the nuclear test ban treaty?

en.wikipedia.org...

At the old met office I worked at, we used to monitor air samples daily for changes in radiocativity. They have acoustic stations across the earth to detect any underground nuclear explosions. Networks in Japan, China, Russia and South Korea all recorded North Koreas tests.

yeppers, like that one.
And the one that caused the Phuckit tsunami too.
Pakistan has 100 nukes to play with before AQ launches against us. Should be interesting.

I assume you mean Phuket Tsunami...

And that was the one that happened on 26th December 2004. It was not caused by a nuclear device. Like I mentioned, it was caused by a massive subduction over a large area.

Do you have a source for your sensational claim?

LMFAO

I suppose if I had put that in the opening post I wouldve got more replies. Maybe the truth isnt exciting enough

So how plausable is the gloom and doom threads on this matter?
Is it gonna wreak havoc or is it just some bullpoop.
I have heard that that area is the epicentre of catastrophe...is that plausable or is it a pipedream?
Thanks for the info.

What ARE you on about???

The man is simply explaining earthquakes, and I for one appreciate the education.

Why do people have to put conspiracy and religion into even the most basic of threads.

They existed before you were born and will exist long after you are dead.

Just take this thread as what it is, as previously explained as earthquakes for dummies.

Sheeesch.....

It is plausible. Its right on the edge of the pacific rim and is quite active at the moment. Seattle is a bit of a worry to. I hear that it lies ona quite a bit of swamp or soft soil.

If a major earthquake occured here, then that city would be in deep trouble.

Just another thing, the first map actually shows that there are many volcanoes in that area to. These would also be a source of some seismic activity
