Satellite imagery of the eruption shows fiery hot lava against a landscape covered in snow.

The heat signature from lava erupting on Iceland's Reykjanes Peninsula is seen in this image captured by one of the Copernicus Sentinel-2 satellites on Feb. 8, 2023, less than 10 hours after the event began. Iceland's Reykjanes Peninsula has crackedagain, creating a nearly 2-mile-long volcanic dyke that has allowed lava to shoot up as high as a 20-story building.sent molten rock sluicing across a snow-covered landscape.

seen above in an image acquired by one of the Sentinel-2 satellites, and in this one captured by Landsat-9 on Feb. 10:In natural color views, the lava is faint — if it's visible at all. But in the infrared, it burns brightly. So to create this compelling image, visible and infrared data were combined.This is the third eruption on the Reykjanes Peninsula since December. The remains of the second one, which occurred in January, can be seen to the south and a little east of the current event.

Luckily, the lay of the land around the new fissure channeled most of the fresh lava into an unpopulated area to the east. This spared the town of Grindavík to the south.

A plume of ash and gas billows from the new Icelandic eruption about seven hours after it began, as seen in this image captured by NASA's Terra satellite on Feb. 8, 2023. New lava stopped pouring from the fissure on Feb. 9, and no volcanic tremors were continuing. "This suggests that the eruption is ending," according toLand is rising at rate of about 0.5 to 1.0 centimeters per day in the area around Svartsengi, home of the Blue Lagoon and the power plant. "Magma thus continues to accumulate in the magma reservoir beneath Svartsengi," according to the Feb. 12 update.
