“Hazards Remain High” as Volcanic Danger Zone is Revealed in NASA Satellite Imagery Captured Over Iceland | UAP

NASA satellite imagery has revealed the thermal signature of volcanic activity that reawakened on Iceland’s Reykjanes peninsula this month, following an eruption late last year that prompted evacuations.

Following a surge that began in mid-January, new fissures opened near the town of Grindavík that released lava over 48 hours. Barriers constructed in the area helped divert the flow away from the town, which remains perilous as volcanic activity continues.

The recent eruptions were the fifth that have occurred on the peninsula since 2021.

Watching from above as the hazardous activity has unfolded in recent weeks, NASA’s Landsat 9 satellite and its Thermal Infrared Sensor 2 (TIRS-2) instrument have collected data that reveals key areas where the volcanic activity is concentrated.

TIRS-2 can detect thermal radiation at two different wavelengths, which conveys the intense heat concentrated around areas where lava flows earlier this month made their way to the surface.

According to NASA’s Earth Observatory, which provides data, imagery, and resources related to climate, geology, as well as other Earth systems, TIRS-2 collected the thermal data as Landsat 9 passed overhead on January 16, which has now been superimposed over a digital elevation model of the affected region.

In December, nearly 4,000 residents were evacuated from Grindavik, followed by a volcanic fissure eruption on December 18 on Sundhnúkagígaröðin, located east of Mt. Sýlingarfell, according to a statement provided by Iceland’s Meteorological Office.

The December eruption was preceded by a “powerful seismic swarm” that began at approximately 21:00 the same day.

Activity has continued since that time, with an additional…
