A magmatic lull is a period of declined magmatic activity in volcanically active regions. They may occur as a result of underthrusting of hinterland lithosphere beneath a volcanic arc, changes in subduction parameters such as relative velocity, direction and slab dip (e.g. flat slab subduction), [1] arc-arc collisions [2] and subduction hinge advance.

The model consists of a degree and order 12 spherical harmonic expansion of the magnetic scalar potential of the geomagnetic main field generated in the Earth's core. [2] Apart from the 168 spherical-harmonic "Gauss" coefficients, the model also has an equal number of spherical-harmonic secular variation coefficients predicting the temporal ...
A magnet's North pole is defined as the pole that is attracted by the Earth's North Magnetic Pole, in the arctic region, when the magnet is suspended so it can turn freely. Since opposite poles attract, the North Magnetic Pole of the Earth is really the south pole of its magnetic field (the place where the field is directed downward into the ...
Belsten specializes in the Fortnite: Battle Royale game and its variants, and was the second streamer to receive their own Fortnite outfit as part of the Fortnite Icon Series, after Ninja. [7] She was one of the leading streamers to compete in the inaugural Fortnite Summer Smash tournament to be hosted at the Australian Open in 2019, and ...

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 Anahim Volcanic Belt can be organized into three groupings: the western section, which has been reduced to remnants of eruptive breccia, high-level plutons and dike swarms; the central section, which consists of predominantly shield volcanoes; and the eastern section, which comprises several small cinder cones and is the location of all ...
The Crater Highlands are made up of several large volcanic complexes, including the 2.4-2.2 Ma Lemagarut and 2.25-2.0 Ma Ngorongoro basalt-trachybasalt-trachyandesite volcanoes (Ngorongoro also contains trachydacite) and the 1.6-1.5 Ma Oldeani basalt-trachyandesite volcano.
