This image, taken on September 30 by the Copernicus Sentinel-2 mission, shows the lava flow from the erupting volcano on the Spanish island of La Palma. The lava flows into the Atlantic Ocean and extends the coastline. This ‘lava delta’ covered about 20 hectares when the photo was taken.
On September 19, a fissure opened in the Cumbre Vieja volcano, sending plumes of ash and lava into the air. The lava poured down the mountain and flowed through villages swallowing everything in its way. By September 28, the 6 km lava flow had reached the ocean on the west coast of the island. Clouds of white steam were reported where the red-hot lava hit the water in the Playa Nueva area.
This Sentinel-2 image is rendered in true color, using the shortwave infrared channel to emphasize the lava flow. The Sentinel-2 mission is based on a constellation of two identical satellites, each carrying an innovative high-resolution multispectral wide-angle camera with 13 spectral bands, capable of tracking changes in Earth’s land and vegetation.
