NASA has captured stunning imagery of a recent volcanic eruption in the snowy expanse of Iceland, where bright red lava poured from the Reykjanes peninsula.
The latest eruption, which marks the third such event since December 2023, started early on February 8, with lava shooting up to 80 meters high along a three-kilometer fissure near Mount Sýlingarfell.
NASA Captures Bright Red Lava Eruption in Iceland
This volcanic activity has drawn both awe and concern from locals and experts alike as it was situated north of the fishing village Grindavík and east of the Svartsengi power station and Blue Lagoon geothermal spa.
Utilizing advanced satellite technology, NASA's Operational Land Imager-2 (OLI-2) aboard Landsat 9 captured an image of another eruption on February 10.
This image, combining infrared and visible observations, shows the heat signature of the lava against the snowy landscape. Notably, cooler lava expelled in January near Grindavík appears black in contrast to the newer, fiery eruptions.
Despite the relatively remote location of the fissure, the lava flow has posed challenges to nearby infrastructure, according to NASA. Even though much of the lava flowed eastward into unpopulated areas, some streams encroached westward toward the power plant and spa.
Protective measures, including earthen defensive walls, were employed to safeguard these facilities. However, the lava managed to breach a crucial hot water pipeline and two roads, prompting authorities to undertake repairs and restore essential services to affected areas.

Plume of Gas and Ash
In the eruption's aftermath, satellite imagery captured by NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) revealed a plume of gas and ash billowing southwestward.
According to NASA, this event was characterized by effusive lava flows, resulting in minimal ash emissions that posed no threat to air travel. Analysis of the volcanic plume revealed typical components such as water vapor, sulfur dioxide, and carbon dioxide, along with traces of other volcanic gases.
Scientists from the Icelandic Met Office and the University of Iceland noted interactions between magma and groundwater, contributing to the plume's composition.
Additionally, data from the Tropospheric Monitoring Instrument (TROPOMI) detected sulfur dioxide within the plume, providing valuable insights into the eruption's atmospheric impact.
While initial reports suggested a waning of volcanic activity following the eruption, subsequent observations indicated a resurgence in seismic activity near the Svartsengi area. Monitoring efforts revealed increased land surface swelling reminiscent of precursory signs observed before eruptions.
The Icelandic Met Office cautioned that this cycle of volcanic activity may continue in the coming weeks, underscoring the need for ongoing vigilance and preparedness.
