Which volcano was formed by the subduction of the Cocos plate under the Caribbean plate?

The Cocos Plate in the Pacific Ocean is subducted beneath the Caribbean Plate, just off the western coast of Central America. This subduction forms the volcanoes of Guatemala, El Salvador, Nicaragua, and Costa Rica, also known as the Central America Volcanic Arc.

Does the Cocos Plate have volcanoes?

Plate another small plate, the Cocos Plate, is being underthrust beneath Mexico and Central America. A belt of volcanoes extends from northern Panama to western Mexico, and virtually all of the highest mountains in this belt are volcanic.

What is happening at the Cocos Plate and the Caribbean plate?

This subduction-subduction-transform (SST) triple junction is referred to hereafter as the NACC triple junction. Off the Pacific coast, the Cocos plate is subducted beneath both the North American and Caribbean plates, which are separated by a sinistral transcurrent boundary.

What landforms are created at the boundary of the Cocos Plate and the Caribbean plate?

The northern boundary of the plate is the Middle America Trench. The eastern boundary is a transform fault, the Panama Fracture Zone. The southern boundary is a mid-oceanic ridge, the Galapagos Rise. The western boundary is another mid-ocean ridge, the East Pacific Rise.

What type of plate is Cocos Plate and Caribbean Plate?

The Cocos Plate is bounded by several different plates. To the northeast it is bounded by the North American Plate and the Caribbean Plate. To the west it is bounded by the Pacific Plate and to the south by the Nazca Plate.

Is the Cocos Plate subducting beneath the Caribbean plate?

The Cocos Plate in the Pacific Ocean is subducted beneath the Caribbean Plate, just off the western coast of Central America. This subduction forms the volcanoes of Guatemala, El Salvador, Nicaragua, and Costa Rica, also known as the Central America Volcanic Arc.

Is the Cocos Plate subducting?

Summary. Western Mexico, where the young and small Rivera Plate and the adjacent large Cocos Plate are subducting beneath the North American Plate, is a unique region on Earth where tearing of subducting oceanic plates, as well as fragmentation of the overriding continental plate, is occurring today.

Is the Cocos Plate convergent or divergent?

Compared to the other tectonic plates in the region, the Cocos Plate is converging with the Caribbean Plate at a steady rate of about 78 millimeters per year based on data from ISCO over 10 months.

What is the name of the tectonic plate that is subducting under Chile?

The subduction of the Nazca plate under southern Chile has a history of producing massive earthquakes, including the largest ever recorded on earth, the moment magnitude 9.5 1960 Valdivia earthquake.

Who discovered Cocos Plate?

Maximilian Goetz. The formation of the Cocos Plate resulted from the breakup of the Farallon Plate at approximately 23 Ma (caused by the East Pacific Rise) when it split creating the Cocos Plate and the larger Nazca Plate to the south of the spreading center.

How was Cocos ridge formed?

The Cocos Ridge (CR), which formed when the Cocos Plate drifted over the Galapagos Hotspot (Walther, 2003) , is a bathymetric high reaching about 2 km above the surrounding seafloor and stretching about 2000 km long and 200-300 km wide across the Cocos Plate .

What type of plate margins are volcanoes in the Caribbean associated with?

The arc is composed of 17 active volcanoes of calc-alkaline composition, caused by subduction of the South American Plate in the Atlantic Ocean under the Caribbean Plate.
