Cold-water Geyser
Cold-water geysers have eruptions similar to those of hot-water geysers, except that -bubbles drive the eruption instead of steam from the proximity to magma. In cold-water geysers, -laden water lies in a confined aquifer, in which water and are trapped by less permeable overlying strata. This water and can escape this strata only in weak regions like faults, joints, or drilled wells. A drilled borehole provides an escape for the pressurized water and to reach the surface. The magnitude and frequency of such eruptions depend on various factors such as plumbing depth, concentrations, aquifer yield, etc. The column of water exerts enough pressure on the gaseous so that it remains in the water in small bubbles. When the pressure decreases due to formation of a fissure, the bubbles expand. This expansion displaces the water and causes the eruption. Cold-water geysers may look quite similar to their steam-driven counterparts; however, often -laden water is more white and frothy. Th ...

Geysir Andernach 2009
Geysir (), sometimes known as The Great Geysir, is a geyser in southwestern Iceland. It was the first geyser described in a printed source and the first known to modern Europeans. The English word ''geyser'' (a periodically spouting hot spring) derives from Geysir. The name ''Geysir'' itself is derived from the Icelandic verb '' geysa'' ("to gush"). Geysir lies in the Haukadalur valley on the slopes of Laugarfjall hill, which is also the home to Strokkur geyser about south. Eruptions at Geysir can hurl boiling water up to in the air. However, eruptions may be infrequent, and have in the past stopped altogether for many years at a time. History The research of sinter shows that Geysir has been active for approximately 10,000 years. The oldest accounts of hot springs at Haukadalur date back to 1294, when earthquakes in the area caused significant changes in local neighbouring landscape creating several new hot springs. Changes in the activity of Geysir and the surrounding ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Water Geysers
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Geysers
A geyser (, ) is a spring characterized by an intermittent discharge of water ejected turbulently and accompanied by steam. As a fairly rare phenomenon, the formation of geysers is due to particular hydrogeological conditions that exist only in a few places on Earth. Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma. Generally, surface water works its way down to an average depth of around where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent (a hydrothermal explosion). A geyser's eruptive activity may change or cease due to ongoing mineral deposition within the geyser plumbing, exchange of functions with nearby hot springs, earthquake influences, and human intervention. Like many other natural phenomena, geysers are not unique to Earth. Jet-like eruptions, often referred to as cryoge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andernach Geyser
Andernach Geyser (german: Geysir Andernach, previously ''Namedyer Sprudel'') is the highest cold-water geyser in the world, reaching heights of 30 to 60 metres. The geyser was first bored in 1903 on the Namedy Peninsula (''Namedyer Werth'') in the Rhine near Andernach. In 2006 it was turned into a tourist attraction and one of the sights in the volcano park and part of the Geopark Vulkanland Eifel. History It is said that in 1903 on the Namedy peninsula, a 343-metre-deep borehole was driven into carbonic acid deposits in order to extract carbon dioxide for mineral water. The reason for boring the hole at this location was that bubbles were seen rising in the waters of the old Rhine ox-bow lake. When the cold-water geyser initially erupted, it leapt to a height of 40 metres. The "Namedy Fizz" (''Namedyer Sprudel'') as it was formerly called, as was the resulting bottled mineral water expelled as a result of fizzing carbon dioxide, was used commercially and soon thereafter fo ...

Wallender Born
The Wallender Born or Wallenborn (popularly known as the Brubbel) is a cold water geyser in the village Wallenborn (Eifel district, Germany). It is adjacent to the reactivated Andernach Geyser (aka ''Namedyer Sprudel'') an active cold water geyser in Germany. Experts disagree on whether the Wallender Born can be described as eruptive course, but periodic gas outbreaks have been witnessed since time immemorial. Until being drilled, Wallender Born was therefore at least a (periodic) mofette. The high water surge of a typical hot spring was found only after construction work. The fountain is operated geyser-like: The artificial conduit is located below the water surface of a small pond. The water is therefore not thrown like a fountain, but turbulent. The "fuel gas" of the geyser is carbon dioxide. It contains traces of other gases like hydrogen sulfide which leads to a smell reminiscent of rotten eggs. Interval between eruptions The eruptions of the Wallender Born occur roughly ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herľany
Herľany (german: Herlein; hu, Ránkfüred) is a village and municipality in Košice-okolie District in the Košice Region of eastern Slovakia. History In historical records, the village was first mentioned in 1487. Geography The village lies at an altitude of 365 metres and covers an area of 9.914 km2. It has a population of about 290 people. Sights The village is known for the only full-scale geyser in Slovakia, one of the few cold water geysers in the world. It erupts periodically (24–32 hours) and erupts water to the 10–15 m height since 1872. Eruption lasts around 25 minutes.
