A hotspot's position on the Earth's surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them. There are two hypotheses that attempt to explain their origins. One suggests that hotspots are due to mantle plumes that rise as thermal diapirs from the core–mantle boundary. [2]
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.
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 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 ...
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.
Lonely Planet has unveiled its best-in-class travel list for 2025, with trending Toulouse, France, taking the top spot for a city break. In the 15th edition of Lonely Planet’s “Best in Travel ...
The Réunion hotspot is a volcanic hotspot which currently lies under the island of Réunion in the Indian Ocean. The Chagos-Laccadive Ridge and the southern part of the Mascarene Plateau are volcanic traces of the Réunion hotspot. [1] The hotspot is believed to have been active for over 65 million years.
Io completes one orbit around the planet every 42.5 hours. Jupiter’s massive gravitational influence squeezes Io as it orbits the planet, like a hand squeezing a rubber ball, which warms up the ...
