NASA Captures Satellite tv for pc Picture Displaying Crimson-Sizzling Lava Oozing From Iceland’s Volcanic Eruption
NASA has captured a satellite tv for pc picture of red-hot lava oozing from Iceland’s most up-to-date volcanic eruption. The unimaginable shot, which additionally reveals a big billow of smoke and fuel arising from the eruption, has been snapped by OLI-2 (Operational Land Imager-2) on Landsat 9. The lava has flowed throughout main roads and closed in on the Blue Lagoon, a preferred vacationer vacation spot, after erupting from a fissure within the Sundhunkur crater sequence on Iceland’s Reykjanes Peninsula. That is the seventh occasion of a volcanic eruption within the space in lower than a yr.
“This pure colour scene [in the picture], acquired by the OLI-2 on November 24, is overlaid with an infrared sign to assist distinguish the lava’s warmth signature,” learn a press release by NASA’s Earth Observatory.
“A plume of fuel, consisting primarily of sulfur dioxide, streamed from the lava, though the eruption didn’t have an effect on flights to and from Iceland,” it added.
In line with the Icelandic Meteorological Workplace, the eruption’s exercise had not decreased as rapidly as was seen in earlier eruptions however had steadied within the final 24 hours.
“Eruptive exercise has been regular during the last 24 hours, with lava now flowing predominantly east and southeast, in direction of and alongside the bottom of Fagradalsfjall,” learn an replace, dated November 27.
“The lava subject close to Fagradalsfjall has expanded barely however continues to thicken. Volcanic tremor has remained steady alongside eruptive exercise within the vent. The speed of subsidence round Svartsengi has considerably diminished,” it added.

What’s a fissure eruption?
As per scientists, Iceland’s present eruption is a fissure eruption. A fissure is a fracture by means of which a sheet of magma flows. When this fracture intersects with the floor, lava erupts onto the floor. In line with a BBC report, the Reykjanes Peninsula had been inactive for 800 years earlier than volcanic exercise resumed in 2021.
Volcanologists have warned that volcanic exercise in Iceland had entered a brand new period. The nation is house to 33 lively volcanic programs, greater than every other European nation. It’s situated on the Mid-Atlantic Ridge, a fault within the ocean ground that separates the Eurasian and North American tectonic plates and causes earthquakes and eruptions.
