Under Volcano is a project carried out on the island of La Palma between the months of October and November 2021 during the eruption of the Cumbre Vieja volcano.

   The Cumbre Vieja volcano, which the Palmeros had once baptized as " Teneguia ", erupted three hundred years after the previous time. This 1971 was the last that occurred on the surface of the earth in Spain.

   The Cumbre Vieja Natural Park, is located on the island of La Palma, in the Canary archipelago, Spain. It covers the entire south-central part of the island, spreading through 6 municipalities. On September 19, 2021, a volcanic eruption began in the area, which lasted three months.

   In the area, a large part of the volcanic cones, product of the fissure activity of the last million years, including most of the historical eruptions of the island, are located. All these eruptive processes are aligned along the central axis of the Cumbre Vieja with lavas that flowed down the slopes, reaching the sea at times and eventually gaining ground from the sea. The Northernmost sector of the park belong to much older geological unit called Paleopalma.

   The island of La Palma is very young in geological terms, barely two million years old, although it began to form under the sea four million years ago. But the island has two very clearly differentiated parts: the north, older and more solid, compared to the south, younger and still in formation. The magma continues to expand the island in the southern part. In fact, all the last volcanoes that have arisen in the last centuries have occurred in that area, such as San Juan in 1949, or Teneguia, half a century ago.
