Intermittent spring

Intermittent spring

Intermittent spring of Yellowstone

An intermittent spring, the geyser (かんけつせん British: geyser) are hot springs spouting out with steam and boiling water in a constant period.

Iceland, an intermittent spring of Yellowstone of the United States of America are world-famous.

There are the "hollow opinion" "perpendicular pipe theories" in the organization of the intermittent spring. It is as follows and writes down the details of the detailed exposition.

Hollow opinion

As for the hollow opinion, the groundwater which collected in the cavity in the basement is warmed by terrestrial heat. It is an opinion to become the steam, and to spout out on the surface of the earth. It is study and the J Machen sea which it investigated in Iceland in 1,811 years that proposed a hollow opinion first. In Japan, it was studied by Kotaro Honda, Torahiko Terada and others. In Honda, Terada, a theory built the large hot water intermittent spring which there was in Atami Onsen as a model.

I explain an opinion hollow than a figure of hollow opinion summary. As shown, hollow A exists underground and is connected to the ground through spout pipe a. When intracavernous water is heated by terrestrial heat, and a steam pressure in hollow A rises, I push the water which collected in spout pipe a. When some quantity is gushed, a steam pressure in spout pipe a decreases, and a spout stops. When groundwater is supplied from pipe c, and a steam pressure of hollow A rises again, spouts happen again. While I repeat a spout, a stop several times, low temperature groundwater is supplied to hollow A, and a steam pressure of cavity A largely decreases and enters at pipe b and pipe c for a long-term interval.

As for the hollow opinion, the large-scale intermittent spring spouting out can explain a large quantity of hot springs for a long time. However, it was difficult to explain the principle of the hollow small intermittent spring which was not recognized under the ground.

Perpendicular pipe theory

The perpendicular pipe theory was proposed in 1847 by German Roberto Bunsen [1].

There is spout pipe a relatively perpendicularly for the ground, and groundwater collects in spout pipe a. The groundwater which collected is heated by terrestrial heat, and a lower department reaches the boiling point. When a lower department begins boiling, a bubble of the occurring steam begins to climb into spout pipe a, and gentle gush starts it in form pushed in it on the surface of the earth. As bubbles in spout pipe a increase, the result that the water pressure in the jurisdiction decreases, the boiling point of the lower part fall down, and an intense spout begins including boiling (bumping) at a stretch.

When a spout continues for a while, heated water in the jurisdiction disappears, and the spout is finished and enters for an interval. New groundwater flows from pipe b leading to spout pipe a and is heated up until the next boiling start.

Japanese Kimio Noguchi announces the article in support of a perpendicular pipe theory from the amount of change such as the chloride ions in the intermittent spring in 1939.

Generally, there is little quantity of one spout, and it is said that a spout period is suitable for the explanation of the intermittent spring from several minutes to dozens of minutes. In addition, I can completely explain the mechanism of the intermittent spring caused by hot spring exploration bowling. The spout of the warm water intermittent spring containing a large quantity of carbon dioxide began by trial boring carried out in Tsuwano-cho, Shimane in 1997, but can explain it by mechanism of the bumping of the same verticality jurisdiction (the tornado hell of Oita Shibaseki Onsen is the same).
