Where is the New England hotspot?
In the Atlantic, one of the longest hot spot tracks is the Great Meteor, or New England hot spot, located at 28ºW, 33ºN. It formed the New England seamount chain and the magma intrusions of the White Mountains.
What is a famous hotspot volcano?
Major hot spots include the Iceland hot spot, under the island of Iceland in the North Atlantic; the Réunion hot spot, under the island of Réunion in the Indian Ocean; and the Afar hot spot, located under northeastern Ethiopia. Volcanic activity at hot spots can create submarine mountains known as seamounts.
Is there a hot spot in the Atlantic Ocean?
The New England hotspot, also referred to as the Great Meteor hotspot and sometimes the Monteregian hotspot, is a volcanic hotspot in the North Atlantic Ocean.
Where is the Great Meteor Seamount?

Where are hotspots located?
Most of these are located under plate interiors (for example, the African Plate), but some occur near diverging plate boundaries. Some are concentrated near the mid-oceanic ridge system, such as beneath Iceland, the Azores, and the Galapagos Islands. A few hotspots are thought to exist below the North American Plate.
What is the name of the underwater chain of volcanoes found in the Atlantic Ocean?
The New England Seamounts
The New England Seamounts, in the western North Atlantic, are the middle portion of a long-lived hotspot chain that extends from Canada to undersea volcanoes on the African tectonic plate.
Why is there a hotspot under Hawaii?
One explanation that scientists have proposed for hot-spot volcanism is that it occurs near unusually hot parts of Earth’s mantle, the layer of the planet below the crust. In the case of the Hawaiian Islands, the Pacific Plate is continually moving to the northwest over the Hawaiian hot spot.
Is the Hawaiian hotspot still active?
The Hawai’i hotspot is a volcanic hotspot located near the namesake Hawaiian Islands, in the northern Pacific Ocean. Four of these volcanoes are active, two are dormant; more than 123 are extinct, most now preserved as atolls or seamounts. …
Do hotspots align with ocean ridges?
A string of hotspots (Tristan, Gough, Discovery, and Shona) aligned with the southern Mid-Atlantic Ridge (MAR) may be contributing magma supplies that maintain the ridge.
What is Iceland plume?
The Iceland plume is a postulated upwelling of anomalously hot rock in the Earth’s mantle beneath Iceland. It is believed that a mantle plume underlies Iceland, of which the hotspot is thought to be the surface expression, and that the presence of the plume enhances the volcanism already caused by plate separation.
How far below sea level is the Meteor Seamount?
270-m
First Paragraph. Great Meteor Seamount is one of the largest seamounts in the Atlantic Ocean, rising from 4200-m depth at the seafloor to 270-m depth beneath the sea surface (Figure 1). Its elliptical plateau encompasses an area of 1500 km2, roughly matching the size of the Spanish island of Gran Canaria.
What is the height of the Rehoboth Seamount?
1,217 m
Several other New England seamounts outside the US EEZ are significant biologically because they rise to relatively shallow depths. They include Balanus (1,469 m), Kelvin (1,599 m), Atlantis II (1,645 m), Gosnold (1,409 m), Gregg (893 m), San Pablo (1,093 m), Manning (1,312 m) and Rehoboth (1,217 m).
