What damage did lava cause to roads and geothermal pipelines?

Question

Accepted Answer

Lava Flow Causes Significant Damage to Infrastructure and Disrupts Services

The recent volcanic eruption in Iceland has resulted in substantial damage to critical infrastructure, notably impacting roads and geothermal pipelines. Lava flows covered the primary access route to the popular Blue Lagoon geothermal spa, leading to its closure. Furthermore, the molten rock directly affected hot water pipes, disrupting the supply of geothermally-heated water to several areas on the Reykjanes peninsula amidst freezing temperatures.
Disruption of Geothermal Hot Water Supply

The eruption's lava flows struck hot water pipes that are integral to supplying geothermally-heated water across the Reykjanes peninsula. This direct impact necessitated the closure of schools, kindergartens, museums, and other public institutions on Friday due to the lack of this essential service. While electricity and potable water remained available, the absence of hot water presented a significant challenge in the region, where temperatures dropped to -8 degrees Celsius (17.6 Fahrenheit) early on Friday.
Impact on the Blue Lagoon and Access Roads

The main access road leading to the Blue Lagoon, a renowned luxury geothermal spa and significant tourist attraction, was inundated by lava. This event led to the spa being closed to the public, despite the main pool area remaining undamaged. Satellite imagery indicated that lava flows extended approximately 4.5 km west of the eruption site, reaching within 500 metres of the Blue Lagoon, which had been evacuated the previous day.
Comparison to Previous Eruptions and Infrastructure Resilience Efforts

Unlike a previous outbreak in December, the latest volcanic event did not result in any damage to residential homes. This contrasts with the earlier eruption that impacted the town of Grindavik, causing several houses to burn down. In response to the ongoing volcanic activity, authorities have been working to restore hot water supply through an emergency pipeline, with approximately 20 personnel working overnight to expedite the process. While initial hopes were to restore supply during the day, this was delayed until midnight, with the potential for full pipe pressure to take up to two days to achieve.
