Frying Pan Lake
Frying Pan Lake (renamed Waimangu Cauldron in 1963 though not widely used) is the world's largest hot spring. It is located in the Echo Crater of the Waimangu Volcanic Rift Valley, New Zealand and its acidic water maintains a temperature of about . The Lake covers in part of the volcanic crater and the shallow lake is only deep, but at vents, it can go down to . Echo Crater was formed as part of the 1886 Mount Tarawera eruption, which opened several Volcanic crater, craters along a rift stretching southwest from Mount Tarawera to the nearby Southern Crater. After this event, the crater's floor partly filled with rainwater and heated groundwater, but it was not until after a large eruption in Echo Crater on 1 April 1917 that the resulting larger crater filled up from hot springs to reach its current size by mid 1918. The most recent eruption in Echo Crater occurred on 22 February 1973, destroying the Trinity Terrace area on the south-eastern shore of Frying Pan Lake. An area ...

Waimangu Volcanic Rift Valley
The Waimangu Volcanic Rift Valley is the hydrothermal system created on 10 June 1886 by the volcanic eruption of Mount Tarawera, on the North Island of New Zealand. It encompasses Lake Rotomahana, the site of the Pink and White Terraces, as well as the location of the Waimangu Geyser, which was active from 1900 to 1904. The area has been increasingly accessible as a tourist attraction and contains Frying Pan Lake, which is the largest hot spring in the world, and the steaming and usually pale blue Inferno Crater Lake, the largest geyser-like feature in the world although the geyser itself cannot be seen since it plays at the bottom of the lake. ''Waimangu'' is a Māori-language word meaning "black water". This name comes from the water that was thrown up by the Waimangu Geyser, which was black with mud and rocks. From the 1890s onwards, the valley has gradually been re-populated naturally by plants ranging from hot water-loving :w:Cyanobacteria, algae and :w:Chloroflexus aurant ...

Hydrothermal
Hydrothermal circulation in its most general sense is the circulation of hot water (Ancient Greek ὕδωρ, ''water'',Liddell, H.G. & Scott, R. (1940). ''A Greek-English Lexicon. revised and augmented throughout by Sir Henry Stuart Jones. with the assistance of. Roderick McKenzie.'' Oxford: Clarendon Press. and θέρμη, ''heat'' ). Hydrothermal circulation occurs most often in the vicinity of sources of heat within the Earth's crust. In general, this occurs near volcanic activity, but can occur in the shallow to mid crust along deeply penetrating fault irregularities or in the deep crust related to the intrusion of granite, or as the result of orogeny or metamorphism. Hydrothermal circulation often results in hydrothermal mineral deposits. Seafloor hydrothermal circulation Hydrothermal circulation in the oceans is the passage of the water through mid-oceanic ridge systems. The term includes both the circulation of the well-known, high-temperature vent waters near the ridge c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of The Bay Of Plenty Region
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Rotorua Lakes District
Rotorua Lakes District or Rotorua District is a territorial authority district in the North Island of New Zealand. It has one urban area of significant size, the city of Rotorua. The district is governed by Rotorua Lakes Council, which is headquartered in Rotorua and is headed by a mayor. The district falls within two regional council areas, with the majority of the area and Rotorua city in the Bay of Plenty Region and the rest in the Waikato region. Tania Tapsell has been the mayor of Rotorua since the 2022 local elections. History Rotorua has an unusual history, as the town was built by the Government as a tourist destination in the 1880s. Through the Rotorua Borough Act 1922, which achieved royal assent on 28 September 1922, the Rotorua Borough was formed. The inaugural elections for mayor were held in February 1923 and Cecil Clinkard was successful. In 1962, Rotorua was proclaimed a city. In 1979, the status was changed to a district when Rotorua City and Rotorua County ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grand Prismatic Spring
The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world, after Frying Pan Lake in New Zealand and Boiling Lake in Dominica. It is located in the Midway Geyser Basin. Grand Prismatic Spring was noted by geologists working in the Hayden Geological Survey of 1871, and named by them for its striking coloration. Its colors match most of those seen in the rainbow dispersion of white light by an optical prism: red, orange, yellow, green, and blue. History The first records of the spring are from early European explorers and surveyors. In 1839, a group of four trappers from the American Fur Company crossed the Midway Geyser Basin and made note of a "boiling lake", most likely the Grand Prismatic Spring, with a diameter of . In 1870 the Washburn–Langford–Doane Expedition visited the spring, noting a geyser nearby (later named Excelsior). Color The bright, vivid colors in the spring are the ...

Boiling Lake
The Boiling Lake is a flooded fumarole located in Morne Trois Pitons National Park, a World Heritage Site on the island of Dominica. The lake, located east of Dominica's capital Roseau, is filled with bubbling greyish-blue water that is usually enveloped in a cloud of vapour. The Boiling Lake is approximately across and is the second-largest hot lake in the world after Frying Pan Lake, located in Waimangu Valley near Rotorua, New Zealand. History The first recorded sighting of the lake was in 1870 by Edmund Watt and Henry Alfred Alford Nicholls, two Englishmen working in Dominica at that time. In 1875, Henry Prestoe, a government botanist, and Nicholls were commissioned to investigate this natural phenomenon. They measured the water temperature and found it to range from along the edges, but could not measure the temperature at the centre where the lake is actively boiling. They recorded the depth to be greater than . Periodically, there have been fluctuations in the level a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waimangu Geyser
The Waimangu Geyser, located near Rotorua in New Zealand, was for a time the most powerful geyser in the world. The geyser was seen erupting in late 1900. Its eruptions were observed reaching up to in height, and it excited worldwide interest. Day trip visitors from Rotorua were keen to see the geyser erupting regularly for 5–6 hours out of a cycle of about 36 hours, and a tourist trip called the "Round Trip" ran from the summer of 1902/1903.Information panel "Waimangu Geyser 1900–1904" at geyser site The geyser was the catalyst for tourism to the Waimangu Valley. Its workings were apparently created by the great 1886 Mount Tarawera eruption. The water expelled by the geyser was black with rocks and mud from the surrounding terrain, so the indigenous Māori people named the geyser Waimangu, meaning 'Black Waters'. The geyser gave its name to the surrounding geothermal region, the Waimangu Volcanic Rift Valley. Joseph Perry of the Limelight Department of the Salvation ...

Inferno Crater Lake
Inferno Crater Lake is a large hot spring located in the Waimangu Volcanic Rift Valley on the North Island of New Zealand, and the largest geyser-like feature in the world. The actual geyser is not visible, as it plays underwater at the bottom of the lake. However, fumaroles are visible on the lake's shore and the rock wall behind it. The water temperature in the lake shifts from every six weeks, with acidity up to pH 2.2, and lake levels that vary up to , following a complicated 38-day cycle that includes an overflow stage. White silica deposits grow up to the overflow level, and the lake's colour is a result of finely divided silica suspended in the water. At low water levels the lake can be a dull grey colour, changing to an intensely sky blue colour at higher lake levels, in particular after the overflow stage.Information panel "Inferno Crater" at Inferno Crater lookout Inferno Crater was blasted out of the side of the locally prominent Mt Haszard as part of the 1886 Mo ...

Fumarole
A fumarole (or fumerole) is a vent in the surface of the Earth or another rocky planet from which hot volcanic gases and vapors are emitted, without any accompanying liquids or solids. Fumaroles are characteristic of the late stages of volcanic activity, but fumarole activity can also precede a volcanic eruption and has been used for eruption prediction. Most fumaroles die down within a few days or weeks of the end of an eruption, but a few are persistent, lasting for decades or longer. An area containing fumaroles is known as a fumarole field. The predominant vapor emitted by fumaroles is steam, formed by the circulation of groundwater through heated rock. This is typically accompanied by volcanic gases given off by magma cooling deep below the surface. These volcanic gases include sulfur compounds, such as various sulfur oxides and hydrogen sulfide, and sometimes hydrogen chloride, hydrogen fluoride, and other gases. A fumarole that emits significant sulfur compounds is some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
