Iceland builds massive dykes to shield against volcanic lava flows

Icelanders build massive dykes to protect against lava flows from reactivated volcanoes near Reykjavik. The six volcanic systems, active for the first time in nearly 800 years, pose a significant threat to the Reykjanes peninsula, prompting around-the-clock construction efforts to safeguard homes and a crucial power plant.

University of Iceland professor warns of lava flow proximity to Reykjavík

Þorvaldur Þórðarson, a volcanology professor at the University of Iceland, suggests that recent earthquakes in the Reykjanes Peninsula could indicate magma accumulation under Húsfellsbruna, raising concerns about potential lava flows near Reykjavík.

In recent days, Svartsengi, Iceland, has experienced accelerated land rise, reaching up to 8 mm (0.3 inches) daily, attributed to magma accumulation under the area. While seismic activity remains mild, the risk assessment for Grindavík has been downgraded to orange, with a continued high risk for crack collapse.

Recent volcanic activity in the Svartsengi area has led to continuous land uplift, although the exact rate is still being determined through GNSS measurements. Around 200 earthquakes, the largest measuring M1.4, have been recorded near the magma conduit since yesterday. Despite a reduction in earthquake frequency, significant risks, including ground collapse, remain for the nearby Grindavík area.

Another eruption began south-southeast of Hagafell, Reykjanes Peninsula, Iceland at 07:57 UTC on January 14, 2024. The latest images show the lava flowing toward the town of Grindavik. The perimeter was about 450 m (1 470 feet) from the northernmost houses in the town around 08:40 UTC.

Strongest earthquake since 1991 and glacial outburst flood at Grímsvötn volcano, Iceland

Strongest earthquake since 1991 and glacial outburst flood at Grímsvötn volcano, Iceland

A glacial outburst flood has begun at Grímsvötn volcano, located beneath the Vatnajökull glacier in Iceland. In addition, the volcano was hit by a M4.3 earthquake on January 11 — the strongest since measurements began in 1991. Glacial outburst floods are known to increase the likelihood of volcanic eruptions. As a result, the Aviation Color Code for the volcano has been raised to Yellow.
