Mud Pool
A mudpot, or mud pool, is a type of acidic hot spring, or fumarole, with limited water. It usually takes the form of a pool of bubbling mud, as a result of the acid and microorganisms decomposing surrounding rock into clay and mud. Description The mud of a mudpot takes the form of a viscous, often bubbling, slurry. As the boiling mud is often squirted over the brims of the mudpot, a form resembling a mini-volcano of mud starts to build up, sometimes reaching heights of . Although mudpots are often called "mud volcanoes", true mud volcanoes are very different in nature. The mud of a mudpot is generally of white to greyish color, but is sometimes stained with reddish or pink spots from iron compounds. When the slurry is particularly colorful, the feature may be referred to as a paint pot. Geology Mudpots form in high-temperature geothermal areas where water supply is short. The little water that is available rises to the surface at a spot where the soil is rich in volcanic ash, cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salton Sea
The Salton Sea is a shallow, landlocked, highly salinity, saline endorheic lake in Riverside County, California, Riverside and Imperial County, California, Imperial counties in Southern California. It lies on the San Andreas Fault within the Salton Trough, which stretches to the Gulf of California in Mexico. The lake is about at its widest and longest. A 2023 report put the surface area at 318 square miles (823.6 km2). The Salton Sea became a resort destination in the 20th century, but saw die-offs of fish and birds in the 1980s due to contamination from Agricultural pollution, farm runoff, and clouds of Particulate pollution, toxic dust in the current century as evaporation exposed parts of the lake bed. Over millions of years, the Colorado River had flowed into the Imperial Valley and deposited alluvium (soil), creating fertile farmland, building up the terrain, and constantly moving its main course and river delta. For thousands of years, the river alternately flowed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Campi Flegrei
The Phlegraean Fields (, ; ) is a large volcanic caldera west of Naples, Italy. The Neapolitan Yellow Tuff eruption (about 12ka BP) produced just 50 cubic kilometers. It is, however, one of relatively few volcanoes large enough to form a caldera. It is part of the Campanian volcanic arc, which includes Mount Vesuvius, about east of Naples. The Phlegraean Fields is monitored by the Vesuvius Observatory. It was declared a regional park in 2003. The Phlegraean Fields' largest known eruptions have an estimated volcanic explosivity index (VEI) of 7. It is often called a supervolcano in popular media, although the accepted definition for that term is a volcano that has had an eruption with a VEI of 8, the highest level. The area of the caldera consists of 24 craters and volcanic edifices. Most of them lie under the Gulf of Naples. There are effusive gaseous manifestations in the Solfatara crater, which was believed in ancient Rome to be the home of Vulcan, the god of fire. T ...

Solfatara (volcano)
Solfatara () is a shallow volcanic crater at Pozzuoli, near Naples, part of the Phlegraean Fields () volcanic area. It is a dormant volcano, which still emits jets of steam with sulfurous fumes. The name comes from the Latin, ''Sulpha terra'', "land of sulfur", or "sulfur earth". It was formed around 4000 years ago and last erupted in 1198 with what was probably a ''phreatic'' eruption – an explosive steam-driven eruption caused when groundwater interacts with magma Magma () is the molten or semi-molten natural material from which all igneous rocks are formed. Magma (sometimes colloquially but incorrectly referred to as ''lava'') is found beneath the surface of the Earth, and evidence of magmatism has also .... The crater floor was a popular tourist attraction until 2017, as it has many fumaroles and mud pools. The area is well known for its bradyseism. The vapours had been used for medical purposes since Roman times. This volcano is where the thermoacidophil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waiotapu
Waiotapu (Māori for "sacred waters") is an active geothermal area at the southern end of the Okataina Volcanic Centre, just north of the Reporoa caldera, in New Zealand's Taupō Volcanic Zone. It is 27 kilometres south of Rotorua. Due to dramatic geothermal conditions beneath the earth, the area has many hot springs noted for their colourful appearance, in addition to the Lady Knox Geyser, Champagne Pool, Artist's Palette, Primrose Terrace and boiling mud pools. These can mostly be viewed through access by foot, and in addition to a paid and curated experience, naturally forming hot springs appear around the area. The geothermal area covers 18 square kilometres. Prior to European occupation the area was the homeland of the Ngāti Whaoa tribe who descended from those on the '' Arawa'' waka (canoe). The area has a long history as a tourist attraction. While the area has been protected as a scenic reserve since 1931, a tourist operation occupies part of the reserve under a ...

Lassen Volcanic National Park
Lassen Volcanic National Park is a List of national parks of the United States, national park of the United States in northeastern California. The dominant feature of the park is Lassen Peak, the largest lava dome, plug dome volcano in the world and the southernmost volcano in the Cascade Range. Lassen Volcanic National Park is one of the few areas in the world where all four types of volcanoes can be found: plug dome, shield volcano, shield, volcanic cone#Cinder cone, cinder cone, and stratovolcano. The source of heat for the volcanism in the Lassen area is subduction of the Gorda plate diving below the North American plate off the Northern California coast. The area surrounding Lassen Peak is still active with boiling mud pots, fumaroles, and hot springs. Lassen Volcanic National Park started as two separate U.S. National Monument, national monuments designated by President Theodore Roosevelt in 1907: Cinder Cone National Monument and Lassen Peak National Monument.

Geothermal Areas In Lassen Volcanic National Park
The geothermal areas in Lassen Volcanic National Park include several groups of hot springs and fumaroles, as remnants of former volcanic activity, exist in Lassen Volcanic National Park in northeastern California. Most of these lie in or are closely adjacent to Mount Tehama's caldera. ''Bumpass Hell'' is the most spectacular of these, but others of importance are ''Sulphur Works'', ''Little Hot Springs Valley'', ''Boiling Springs Lake'' and ''Devil's Kitchen''. In each thermal area, the highest temperature of water generally is close to the boiling temperature at the altitude of the particular spring or fumarole — at Bumpass Hell and on the northwest flanks of Lassen Peak.NPS: Lassen Volcanic National Park, Nature & science, Volcanoes / Lava Flows Temperatures as high as have been recorded in the park.

West Thumb Geyser Basin
The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. A study that was completed in 2011 found that a total of 1,283 geysers have erupted in Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park. The number of geysers in each geyser basin are as follows: Upper Geyser Basin (410), Midway Geyser Basin (59), Lower Geyser Basin (283), Norris Geyser Basin (193), West Thumb Geyser Basin (84), Gibbon Geyser Basin (24), Lone Star Geyser Basin (21), Shoshone Geyser Basin (107), Heart Lake Geyser Basin (69), other areas (33). Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The h ...
