The abundant geothermal energy that Iceland is using to power its new breed of data centers comes at a cost; the sub-surface activity that generates all that hot water also makes the area prone to volcanic eruptions. Grímsvötn erupted last month, bringing darkness to Rekjavik’s normally bright summer skies and causing some limited disruption to European air traffic. However, according to those behind the island’s Thor Data Center, it kept on operating as normal. They’ve even provided pictures of their air filters to demonstrate how little effect the volcano had on air near their facility.
