Isla Fernandina of the Galapagos Islands is situated on an oceanic tectonic plate, specifically the Nazca Plate. It is part of the Galapagos hotspot, where volcanic activity occurs due to the movement of the Nazca Plate over a stationary mantle plume. This geologic setting leads to the formation of the island through volcanic eruptions.
The tallest of all the Galapagos volcanoes is Wolf Volcano. The Galapagos Archipelago lies over an oceanic platform formed by the a volcanic hotspot underneath the Nazca tectonic plate
The volcanic set up of the Islands can be explained by looking at the theories of Plate Tectonics and the Hot Spot. The platform where the Galapagos Islands started their volcanic growth lies right on top of the Nazca Plate. In Galapagos, the Islands to the East are older than those to the West, this implies that the Galapagos Hot Spot is right under the western Islands of Isabela and Fernandina.
The Galapagos Islands move about 2-3 centimeters per year due to tectonic plate movement. This geological process is known as seafloor spreading, where the Nazca Plate is moving eastward and causing the islands to shift over time.
This is due to hotspots. It is a hot, rising plume of magma that will cause volcanoes and so create an island in the middle of a plate. The classic example of a hotspot is Hawaii in the middle of the Pacific Plate. Hope this helps :)
Hawaii is located in the middle of the Pacific Plate, which is a stable tectonic plate. The Hawaiian Islands were formed by a hot spot underneath the plate, where magma rises and creates volcanic islands as the tectonic plate moves over it. This is why Hawaii is not located at a plate boundary, such as a divergent or convergent boundary.
Fernandina Island is part of the Galapagos Islands, which sit on the Nazca Plate in the Pacific Ocean.

The Santa Cruz Galapagos islands are located on a divergent plate boundary. This means that the tectonic plates in this region are moving away from each other, resulting in the formation of new crust as magma rises to the surface and solidifies.
The Galápagos are located on the very northern edge of the Nazca plate, which is bounded by the Cocos (north), the Pacific (west), the South American (east), and the Antarctic (south) plates

Many of the Caribbean islands were formed by volcanic activity along tectonic plate boundaries, particularly where the North American Plate and the Caribbean Plate interact. This activity has led to the creation of volcanic islands and underwater mountain chains in the region.
The smallest plate tectonic entity is a microplate, which is a small fragment of the Earth's lithosphere that moves independently of major tectonic plates. These microplates are often found in regions where larger plates meet and can play a role in the tectonic processes of a region.
The Aleutian Islands were formed by the collision of tectonic plates. The islands lie along the boundary where the Pacific Plate is being pushed beneath the North American Plate in a process known as subduction. This tectonic activity has led to the creation of a chain of volcanic islands.
