This list of shield volcanoes includes active, dormant and extinct shield volcanoes. Shield volcanoes are one of the three types [ specify ] of volcanoes. They have a short cone shape, and have basaltic lava which means the lava has low viscosity (viscosity is a measure of the ability for a liquid to flow)
Typical shield volcanoes found in California and Oregon measure 3 to 4 mi (5 to 6 km) in diameter and 1,500 to 2,000 ft (500 to 600 m) in height, [6] while shield volcanoes in the central Mexican Michoacán–Guanajuato volcanic field average 340 m (1,100 ft) in height and 4,100 m (13,500 ft) in width, with an average slope angle of 9.4° and ...
New island forming in the Zubair Group, about 0.5 km (0.3 mi) NNW of Rugged Island. NASA satellite image, January 7, 2012. Zubair Group, Al Zubair Group or Zubayr Group (Arabic: مجموعة جزر الزبير, or simply: جزر الزبير) is a group of 10 major volcanic islands, on top of an underlying shield volcano in the Red Sea, which reach a height of 191 m (627 ft) above sea level.
By comparison, from sea floor to peak, Mauna Kea, on Hawaii's Big Island, is the tallest shield volcano on Earth, but it is nowhere near as massive as Pūhāhonu. Another volcano on the Big Island is Mauna Loa ; a 2013 study estimates Mauna Loa's volume at 83,000 cubic kilometres (20,000 cu mi) which is believed to be an overestimate.
Ball's Pyramid is an uninhabited islet in the Pacific Ocean located 20 kilometres (12 mi) southeast of Lord Howe Island, between Australia and New Zealand.The steep rocky basalt outcrop is the eroded plug of a shield volcano and caldera that formed 6.4 million years ago.
The activity of Pleistocene shield volcanoes such as Þráinskjöldur [ˈθrauːɪnˌscœltʏr̥] and Hrútagjá [ˈr̥uːtaˌcauː], as well as of tuyas like Fagradalsfjall within the volcanic system, are seen as separate from the fissure system, although the bigger volcanoes control parts of the topography. [4]
This is because it is more favorable for the emulsifying agent to be at an interface so reducing the interfacial area requires expending energy to return the emulsifying agent to the bulk. Stability of the Macroemulsions are based on numerous environmental factors including temperature, pH, and the ionic strength of the solvent.
Mount Guna (Amharic: ጉና ተራራ, Guna Terara) is a mountain and shield volcano located near the cities of Nefas Mewcha and Debre Tabor, in the northern Amhara Region of Ethiopia. It is the highest point in the South Gondar Zone , with an elevation of 4,120 metres (13,517 ft) above sea level.
