The "Wolf Volcano" you're referring to is most likely Wolf Volcano, located on the Galapagos Islands.

The Galapagos Islands are situated on the Nazca Plate, which is a major tectonic plate in the eastern Pacific Ocean.

It's important to note that Wolf Volcano is a stratovolcano, meaning it is formed by layers of lava flows and volcanic ash. This type of volcano is often associated with subduction zones, where one tectonic plate slides beneath another. In the case of Wolf Volcano, the Nazca Plate is subducting beneath the South American Plate.
