Continuous lava flow threatens Grindavík barriers, Iceland

Continuous lava flow threatens Grindavík barriers, Iceland

The ongoing eruption on Iceland’s Reykjanes Peninsula, starting March 16, 2024, continues to pose a threat as lava from the Sundhnúkur crater row thickens near Grindavík. Extrusion rates have remained consistent at 3 – 4 m3/s (106 – 141 ft3/s), with new data anticipated to further assess the situation.

The eruption that began in Reykjanes Peninsula on March 16, 2024, continues at stable levels. However, the Icelandic Met Office (IMO) has been detecting very unhealthy levels of sulfur dioxide pollution over the past couple of days. Residents are urged to follow instructions provided by the Environment Agency of Iceland and the Office of the National Medical Examiner.

A fissure eruption that started on Reykjanes Peninsula, Iceland on March 16, 2024, continues at a fairly constant rate, with an average lava flow from the craters of about 14.5 m3 per second (512 feet3/s) from March 17 to 20. About 700 people at the Blue Lagoon spa and several in the town of Grindavík were evacuated within a 30-minute period after the start of the eruption.

Bad weather disrupts seismic monitoring, magma volume at Svartsengi increasing, Iceland

Bad weather disrupts seismic monitoring, magma volume at Svartsengi increasing, Iceland

Unfavorable weather conditions have disrupted the earthquake monitoring system on Reykjanes Peninsula by dampening small events, resulting in a lower number of detected earthquakes since Saturday, March 2, 2024. Nevertheless, the volume of magma beneath Svartsengi continues to increase, which could result in a new dike intrusion and possibly an eruption with very short notice.

Magma volume rising, increased likelihood of eruption on Reykjanes Peninsula, Iceland

Magma volume rising, increased likelihood of eruption on Reykjanes Peninsula, Iceland

Magma volume beneath Svartsengi, Reykjanes Peninsula, Iceland continues to increase, which could result in a new dike propagation and/or volcanic eruption in the coming days, the Icelandic Met Office (IMO) reported at 14:00 UTC on March 5, 2024. Weather conditions over the next few days could affect IMO’s monitoring system.

Magma accumulation accelerates land rise near Svartsengi, Iceland

Magma accumulation accelerates land rise near Svartsengi, Iceland

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.
