As Askja Volcano in Iceland rumbles with the imminent threat of eruption, its historic significance in the world of geology takes center stage. This volatile giant, situated in the country’s remote interior, holds an indelible place in scientific annals.
Askja gained fame in 1875 when it erupted dramatically, shaping the field of volcanology. The mysterious disappearance of German scientists Walter von Knebel and Max Rudloff in 1907 while exploring its volcanic lake furthered its enigmatic reputation.
Yet, perhaps its most intriguing chapter unfolded during the summers of 1965 and 1967 when NASA sent 32 astronauts for geological training. These field trips sparked astronauts’ interest in geology, crucial for moon missions. It was here that Apollo astronauts learned to select the lunar rock samples that they later brought home from their missions to the Moon.
Now, with the land rising and the geothermal lake temperatures increasing, Askja’s history comes full circle. As experts debate whether an eruption will be ash or lava-based, its significance is not lost: it continues to teach us about the Earth’s inner workings, just as it prepared astronauts for their lunar journeys.
