橙色熔岩,蓝色泻湖
Lava encroaches on the Blue Lagoon, a popular tourist destination in Iceland, in this Nov. 24, 2024, Landsat 9 image overlaid with an infrared signal. The infrared signal helps distinguish the lava’s heat signature.
A volcanic fissure burst open on Iceland’s Reykjanes peninsula four days prior, heralded by a series of earthquakes. A plume of gas, consisting primarily of sulfur dioxide, streamed from the lava. The Reykjanes peninsula eruption is the seventh in a series of events that began in December 2023.
