A chain of volcanoes is created as the lithosphere moves over the source of magma. In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. [1] Examples include the Hawaii, Iceland, and Yellowstone hotspots.
The Hawaiʻi hotspot is a volcanic hotspot located near the namesake Hawaiian Islands, in the northern Pacific Ocean.One of the best known and intensively studied hotspots in the world, [1] [2] the Hawaii plume is responsible for the creation of the Hawaiian–Emperor seamount chain, a 6,200-kilometer (3,900 mi) mostly undersea volcanic mountain range.
The four-kilometre (2.5 mi) stretch of the Waimangu Volcanic Rift Valley running from Southern Crater to the shores of Lake Rotomahana has been a hotspot of geothermal and hydrothermal activity since the 1886 Mount Tarawera eruption, and contains the three lake-filled craters Southern Crater, Echo Crater, and Inferno Crater, as well as the bush-clad Raupo Pond Crater, Fairy Crater and Black ...
Iceland is one of the most active volcanic regions in the world, with eruptions occurring on average roughly every three years (in the 20th and 21st century until 2010 there were 45 volcanic eruptions on and around Iceland). [1] About a third of the basaltic lavas erupted in recorded history have been produced by Icelandic eruptions.
The Azores hotspot is marked 1 on map. The Azores hotspot is a volcanic hotspot in the Northern Atlantic Ocean. The Azores is relatively young and is associated with a bathymetric swell, a gravity anomaly and ocean island basalt geochemistry. [1] The Azores hotspot lies just east of the Mid-Atlantic Ridge [2]
Map of hotspots. The East Australia hotspot is marked 30 on map. View inside the crater of Mount Schank from the rim. The East Australia hotspot (which is now believed by some scientists to represent multiple hotspots including a southwestern Cosgrove hotspot) is a volcanic province in southeast Australia which includes the Peak Range in central Queensland, the Main Range on the Queensland-New ...
As the seasons change, moods sometimes do too. When temperatures drop and sweater weather is in full swing, some people may begin to notice they feel down and not as engaged with the world around ...
An example of a hotspot volcanic belt is the Anahim Volcanic Belt in British Columbia, Canada, which was formed as a result of the North American Plate sliding westward over the Anahim hotspot. [9] Most hotspot volcanoes are basaltic because they erupt through oceanic lithosphere (e.g., Hawaii, Tahiti). As a result, they are less explosive than ...
