LA PALMA, CANARY ISLANDS - 26 September 2021 - The Operational Land Imager (OLI) on Landsat 8 captured a natural-color image (above) of lava flowing through the communities of El Paraiso and Todoque on September 26, 2021. Though the inside of the lava flow was hot and molten, cooling on the surface left a dark crust that made the flow appear black in natural-color imagery. Observations of infrared wavelengths (second image below) reveal the hottest parts of the flow. The volcanic plume streaming toward the northeast contains a mixture of ash, sulfur dioxide, and other volcanic gases. A lull in activity in the morning on September 27 suggested that the eruption might be winding down, but explosive activity resumed later in the day, according to the Volcanology Institute of the Canary Islands (INVOLCAN). Experts from INVOLCAN have indicated that the current eruption could persist for weeks to months. Cumbre Vieja last erupted 50 years ago. The most recent eruption in the Canary Islands happened in 2011, when an underwater vent at El Hierro came to life - Photo: Geopix/NASA
