NASA has released images of ancient volcanic fissures in Iceland that recently opened up, spewing lava and posing a threat to nearby towns, including Grindavik, which had to be evacuated. The volcanic eruption occurred on January 14, causing the destruction of at least three homes shortly after villagers had evacuated the area. Interestingly, similar eruptions have been happening in the same region since December. According to the latest update from the Icelandic Met Office, the danger persists, as Grindavik is still at risk of lava movements, with additional fissures erupting unexpectedly. NASA has shared images illustrating the significant heat still emanating from the fissures near Grindavik.
The recent eruptions heightened fears as homes were destroyed even after villagers had been safely relocated. Authorities have maintained a high alert status in the region since December due to a series of eruptions. The Icelandic weather office has cautioned that the danger is ongoing, with unpredictable lava flows and the emergence of new fissures.
NASA’s Thermal Insight on Iceland’s Volcanic Unrest
NASA’s Landsat 9 satellite used a thermal infrared sensor to capture the natural phenomenon. The map displayed substantial heat coming from the fractured land surface near Grindavik town, depicting massive fissures filled with intensely hot lava. Despite evacuation efforts, Grindavik remains vulnerable to additional fault movements. NASA’s data reveals ground deformation of up to 4.6 feet under the town due to significant magma movement. Experts are concerned that the area may experience cyclical bursts of volcanic activity.
It’s important to note that last month’s eruption in the Svartsengi volcanic system raised concerns, leading to the evacuation of up to 4,000 Grindavik residents on December 18, who left their homes hoping for a resolution.
Unique Geological Position of Iceland
Iceland is situated between the Eurasian and North American tectonic plates, experiencing heightened seismic and volcanic activity. With these two massive plates moving in opposite directions, Iceland remains a dynamic hotspot for geological phenomena.
