A shield volcano is a type of volcano named for its low profile, resembling a shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity ) lava , which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano .
The topography of Reykjanes Peninsula was formed by glaciers and volcanism, basaltic lava fields covering a good part of the peninsula, in between volcanoes of subglacial as well as subaerial origin, namely tuyas, hyaloclastic ridges (tindars), shield volcanoes and crater rows. [1] Some volcanic systems are submarine, so that there is a ...
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)
Erta Ale (or Ertale or Irta'ale; / ˈərtə ˈeɪl / Amharic: ኤርታሌ) is a continuously active basaltic shield volcano in the Afar Region of northeastern Ethiopia, which is itself part of the wider Afar Triangle (a barren desert region straddling Djibouti, Ethiopia and Eritrea). The volcano is located in the Danakil Depression, an area on ...
Cinder cone. A cinder cone (or scoria cone[1]) is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. [2][3] The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent.

An example is the massive Level Mountain shield volcano in northern British Columbia, Canada, which covers an area of 1,800 km 2 (690 sq mi) and a volume of 860 km 3 (210 cu mi). [ 1 ] Perhaps the most extensive of all the subaerial basaltic plateaus existed during the Paleogene [ 2 ] and possibly extended over 1,800,000 km 2 (690,000 sq mi) of ...
Mountain type. shield volcano. Skjaldbreiður (Icelandic pronunciation: [ˈscaltˌpreiːðʏr̥] ⓘ, "broad shield") is an Icelandic lava shield formed in a huge and quite protracted eruption series from about roughly 9,500 years ago. [ 2 ] The extensive lava fields which were produced by this eruption, flowed southwards, and formed the basin ...
