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.
Lava domes are common features on volcanoes around the world. Lava domes are known to exist on plate margins as well as in intra-arc hotspots, and on heights above 6000 m and in the sea floor. [1] Individual lava domes and volcanoes featuring lava domes are listed below.
The HawaiĘ»i 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.
Iceland is one of the most active volcanic hot spots in the world, as the island is located where two tectonic plates, the Eurasian and the North American plates, are slowly moving away from each ...
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.
An example of a subduction-zone related volcanic belt is the Okhotsk-Chukotka Volcanic Belt in northeastern Eurasia, which is one of the largest subduction-zone related volcanic provinces in the world, stretching some 3,200 kilometres (2,000 mi) and comprising about 2 × 10 6 cubic kilometres (4.8 × 10 5 cu mi) of volcanic and plutonic ...
The Philippines' Kanlaon volcano erupted for nearly four minutes, shooting ash 2.5 miles into the sky and prompting the emergency evacuation of some 87,000 people.
The Indonesian volcano monitoring agency said at least 10,000 people have been affected by the eruption in Wulanggitang District, across the six nearby villages of Pululera, Nawokote, Hokeng Jaya ...
