Learning from the seminar of the new seismology
Why does a deep earthquake occur only in the trench part?
The cause of the deep earthquake was expounded in the new office 23 when it was the explosion of the dissociated water contained in the magma which has convection. Well, why does a deep earthquake occur only in the trench part? Why doesn't an earthquake occur on the deep portion of the ridge? It is very strange there why there is no explosion of the dissociated water. A deep earthquake doesn't occur certainly though a ridge is a seismic frequent occurrence zone. Let's make this mystery clear.
Mantle convection was illustrated with Fig.1. It creeps in the trench part, and has convection inside the earth, and it is raised in the ridge part. A convection phenomenon is not contradiction because it thinks that a mantle is a liquid. A part of the mantle material spouts it as a magma in the bottom of the sea. Therefore, the stripe pattern of the terrestrial magnetism is recorded in the submarine rock board. Most mantle material is moved horizontally under the crust after the rise.
Fig.1 A typical figure of mantle convection It goes down from the trench part, and it is raised in the ridge part.

The movement of the mantle material is divided in three parts and examined.

One is A-B from the trench part to the end which it creeps into in the space.The second is B-C of the main part of the convection.The third is C-D of the rise part. The rate of the dissociated water and the consolidated water (It is distinguished from the dissociated water to make it easy to explain though it is mere water.) of this section is examined. The reason why a mantle rises in the ridge part is the blanket effect examined in the new office 16. That is wrong though a blanket effect is being made the cause of the division and the movement of the continent. A blanket effect is thought to take the cause of the rise and the convection of the mantle material to be right. Mantle material becomes higher temperature than shallow water because deepness of the ridge part hardly misses heat. Of course hot mantle material is raised. In other words, a difference in temperature is the cause of the mantle convection. The cause of the mantle convection is a blanket effect.

Fig.3 The rate of the dissociated water and the consolidated water of the B-C section. 　While it has convection, dissociated water diffuses, and it is diluted.

The rate of the dissociated water and the consolidated water of the A-B section was illustrated in Fig.2. Water repeats a dissociated water ⇒ explosion ⇒ consolidated water every time it gets into a high dissociation area as shown in the new office 23. A repetition lasts until a consolidated water disappears.

Fig.3 showed the rate of the B-C section. This section is the main part of the mantle convection. Dissociated water is diluted due to the diffusion while it is moved through this section. When it reaches a C point(Fig.4) under the ridge, the dissociated water which is lower than a dissociation limit in the mantle material is contained.
Fig.4 The rate of the dissociated water and the consolidated water of the C-D section. 　An earthquake occurs only in the about bottom of the sea.

It doesn't explode unless it exceeds a dissociation limit when mantle material is raised. Therefore, an earthquake doesn't appear on the deep portion of the ridge. When it exceeds a dissociation limit, dissociated water beyond a limit ignites, and explodes, and becomes a consolidated water. This consolidated water (It is mere water.) begins to well up in the form of the black smoke with the dissolution material from the bottom of the sea. It is said that many chimneys which vomit a black smoke stand on the valley of the ridge. A deep earthquake doesn't appear on the ridge part with a phenomenon of only the trench part. This is clear from the above consideration.

"The big global travel notes" of NHK were quoted, and a black smoke was explained at the new office 14. The mechanism of the submarine fountain is expressed after that quotation. Next, that is introduced. Furthermore, it found that the cause of this phenomenon was the circulation of the seawater in the bottom of the sea in the research after that.

First, seawater soaks in the ground from the crack in the bottom of the sea. That water is heated in the magma in the ground and raised. At that time, a metal in the inside of the magma is melted. Heated seawater is cooled rapidly, and it separates a metal in the inside when it touches the seawater of the cold bottom of the sea of the water temperature 2℃.This is raised like black smoke.This is the true character of the black smoke phenomenon. And, chimney-shaped structure is composed of two material which accumulates around the violent outflow mouth. They are a metal in the black smoke and sulfuric acid calcium due to the response with the calcium during the heat water and sulfuric acid ion in the seawater.

The above is that quotation. It doesn't know whether it has the subterranean water phenomenon which is the same as the ground in the deep sea bottom under such uncanny pressure. It is the new interpretation that the water which went through the process of [dissociated water ⇒ earthquake ⇒ consolidated water] spouts from the bottom of the sea.

The figure which classified the distribution form of the deep earthquake in the library 47 was shown. There is an area where a distribution form doesn't continue in that figure. As for a dissociation's not happening only in a certain section, a temperature increase tendency seems to be loose in that section. It can think that it is a temperature constant or a temperature decline only in that section. A continent ( MU continent corresponds.) might be in this area before. That continent sinks due to the big earthquake, and a temperature slope may be different from other areas inside the mantle because of that.
