Its under the South American Plate
the Nazca plate and the South American plate
The thickest part of the South American tectonic plate lies below the Andes Mountains. They were created from the compression of the South American plate with the Nazca Plate and the Antarctic Plate.
The Antarctic plate is surrounded by the South American, African, Australian, and Pacific plates. It interacts with these plates along its boundaries, where tectonic activity such as subduction or spreading occurs.
There are seven major tectonic plates: Pacific, North American, Eurasian, African, Antarctic, Indo-Australian, and South American. These plates are constantly moving and interacting with each other, leading to various geological phenomena like earthquakes and volcanic activity.
There are eight main tectonic plates:North AmericanSouth AmericanNazcaAfricanEurasianIndo-AustralianAntacticPacificThere are also some smaller tectonic plates in which i do not know of
There are roughly 30 tectonic plates, 12 of which are more than 5 million square kilometers in area.
Galeras Volcano is on the Nazca and the South American plates. It is a convergent boundary and a strato volcano.
The seven largest tectonic plates are the Pacific Plate, African Plate, Antarctic Plate, Eurasian Plate, North American Plate, South American Plate, and Indo-Australian Plate. These plates make up the majority of the Earth's surface and are responsible for the movement of the Earth's lithosphere.
