Timanfaya fumaroles

The Timanfaya fumaroles are located within Timanfaya National Park on the Spanish island of Lanzarote in the Canary Islands. These features are found throughout a landscape showcasing solidified lava flows from intense geothermal activity. The park is situated in the southwestern part of the island, representing the site of a significant volcanic eruption.

The intense geothermal activity resulting in the Timanfaya fumaroles was caused by a significant volcanic eruption in 1730. This catastrophic event, which lasted for several years, covered a quarter of the island in solidified lava and volcanic ash. Today, the fumaroles demonstrate the immense heat still trapped just beneath the Earth's interior in this region.

At the El Diablo restaurant in Timanfaya National Park, visitors can observe the park's geothermal activity firsthand, as food is actually grilled using the natural heat from the fumaroles. The intense heat radiating from vents in the Earth's interior reaches temperatures high enough to cook meat instantly. Additionally, park rangers often demonstrate the shallow ground heat by pouring water into boreholes, which instantly erupts as steam.

The Timanfaya fumaroles are vents emitting steam and various gases from the Earth's interior due to lingering magmatic activity. While water vapor constitutes the majority of the visible emission, the vents also release trace amounts of carbon dioxide and sulfur compounds. These gases, along with the intense subterranean heat, demonstrate that the volcanic system beneath Lanzarote is still technically active.
