Runaruna Mud Volcano
Runaruna Mud Volcano as a distinct and true mud volcano landform is considered a national geological place of interest in New Zealand. Several geological processes may cause the formation of mud volcanoes including elsewhere in New Zealand geothermal mud pools or mudpots. It is located just southwest of Broadwood on private property.

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Northland Region
The Northland Region ( mi, Te Tai Tokerau) is the northernmost of New Zealand's 16 local government regions. New Zealanders sometimes refer to it as the Winterless North because of its mild climate all throughout the year. The main population centre is the city of Whangārei, and the largest town is Kerikeri. At the 2018 New Zealand census, Northland recorded a population growth spurt of 18.1% since the previous 2013 census, placing it as the fastest growing region in New Zealand, ahead of other strong growth regions such as the Bay of Plenty (2nd with 15%) and Waikato (3rd with 13.5%). Geography The Northland Region occupies the northern 80% (265 km) of the 330 km Northland Peninsula, the southernmost part of which is in the Auckland Region. Stretching from a line at which the peninsula narrows to a width of just 15 km a little north of the town of Wellsford, Northland Region extends north to the tip of the Northland Peninsula, covering an area of 13,940&nb ...

Far North District
The Far North District is the northernmost territorial authority district of New Zealand, consisting of the northern part of the Northland Peninsula in the North Island. It stretches from North Cape and Cape Reinga / Te Rerenga Wairua in the north, down to the Bay of Islands, the Hokianga and the town of Kaikohe. The Far North District Council is based in Kaikohe, and has nine ward councillors representing three wards: Te Hiku (in the north), Kaikohe/Hokianga (in the west), Bay of Islands/Whangaroa (in the east). The council is led by the current mayor of Far North, Moko Tepania, who entered the role in 2022. Geography The Far North District is the largest of three territorial authorities making up the Northland Region. The district stretches from the capes and bays at the northern tip of the Aupouri Peninsula past Ninety Mile Beach to the main body of the Northland Peninsula, where it encompasses the Parengarenga Harbour, Whangaroa Harbour and Bay of Islands (on the e ...

Mud Volcano
A mud volcano or mud dome is a landform created by the eruption of mud or slurries, water and gases. Several geological processes may cause the formation of mud volcanoes. Mud volcanoes are not true igneous volcanoes as they do not produce lava and are not necessarily driven by magmatic activity. Mud volcanoes may range in size from merely 1 or 2 meters high and 1 or 2 meters wide, to 700 meters high and 10 kilometers wide. Smaller mud exudations are sometimes referred to as mud-pots. The mud produced by mud volcanoes is mostly formed as hot water, which has been heated deep below the Earth's surface, begins to mix and blend with subterranean mineral deposits, thus creating the mud slurry exudate. This material is then forced upwards through a geological fault or fissure due to local subterranean pressure imbalances. Mud volcanoes are associated with subduction zones and about 1100 have been identified on or near land. The temperature of any given active mud volcano generally r ...

Mudpot
A mudpot, or mud pool, is a sort of acidic hot spring, or fumarole, with limited water. It usually takes the form of a pool of bubbling mud. The acid and microorganisms decompose 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 sort of mini-volcano of mud starts to build up, sometimes reaching heights of 1 to 1.5 meters. 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 is in short supply. The little water that is available rises to the surface at a spot where the soil is rich in volcanic ash, clay, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadwood, New Zealand
Broadwood is a town about 25 km to the north of the north side of the Hokianga harbour, in Northland, New Zealand. Herekino is 21 km to the west, and Mangamuka Bridge is the same distance to the east. The Broadwood area was first settled by Pakeha in the 1880s, and an access road was constructed through the area from Takahue to Motukaraka on the Hokianga harbour. An unmetalled road through the Te Karae Valley to Kohukohu was constructed in 1908. Demographics The SA1 statistical area which includes Broadwood covers . The SA1 area is part of the larger Kohukohu-Broadwood statistical area. The SA1 statistical area had a population of 135 at the 2018 New Zealand census, an increase of 15 people (12.5%) since the 2013 census, and a decrease of 27 people (−16.7%) since the 2006 census. There were 48 households, comprising 75 males and 57 females, giving a sex ratio of 1.32 males per female. The median age was 45.5 years (compared with 37.4 years nationally), with 2 ...

Landforms Of The Northland Region
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. 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 ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of The Northland Region
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide p ...
