Volcanic chains such as the Hawaiian Islands form as a result of the movement of a tectonic plate across fixed hot spot beneath the surface.

The eruption that created Surtsey also created a few other small islands along this volcanic chain, such as " J�lnir " and unnamed other peaks.
23.
During the late Cenozoic, a volcanic chain was constructed on top of Mesozoic and Paleozoic rocks and reached a width of in the area of Lastarria.

Volcanic activity in the Quimsachata volcanic chain migrated south from the now deeply eroded Acotango and Humarata volcano to the more recent Capurata and Guallatiri volcanoes.
25.
Waning of the Laramide orogeny coincided with volcanic eruptions from two parallel volcanic chains separated by a long valley in the Yellowstone-Absaroka area to the north.

Currently, Mono Lake is in a geologically active area at the north end of the Mono Inyo Craters volcanic chain and is close to Long Valley Caldera.
27.
The summit of Mammoth Mountain provides panoramic views of the craters and domes of the Mono Inyo volcanic chain, Mono Lake, the Sierra Nevada and Long Valley Caldera.
28.
Magmas from this volcanic chain have a calc-alkaline composition formed by partial melting of a mantle wedge, with research indicating a decrease in SiO 2 concentration over time.
29.
Part of the volcanic chain in the Lesser Antilles arc, Grenada and its possessions generally vary in elevation from under 300 meters to over 600 meters above sea level.
30.
It is considered part of a volcanic chain with the Pastillito and Volcan de la Sal cones, probably dependent on tectonic fractures, which lies in a long north-south valley.
