Risk assessment updated.
eruption on the Sundhnúks crater series has continued with constant activity during the night, just like in the past few days, and there are little changes in the eruption turbulence. The lava flow from the active crater is now mostly southeast to Fagradalsfjall.
The Norwegian Meteorological Agency's experts measured the emission of SO 2 from the eruption yesterday, November 28. The measurements showed that about 64 - 71 kg/s of SO 2 flowed from the eruption. Gas pollution from the eruption over the next few days can therefore continue to be expected, which could cause discomfort or be unhealthy. This is especially true on the hiking trails at Fagradalsfjall and are close to the geysers. Here you can access gas distribution forecasts from the weather watch.
The second largest eruption in the Sundhnúks crater series
The experts of the National Institute of Natural Sciences were also taking measurements yesterday and flew over the eruption centers. The results of their measurements showed that the lava bed that has been formed in this volcanic eruption has an area of 9.1 km 2 , its volume is about 47 million m 3 and the lava bed is on average just over 5 m thick.
This eruption, which started 9 days ago, has thus become the second largest in volume of the eruptions that have occurred in the Sundhnúks crater series since December 2023.
lava bed that formed in the volcanic eruption, which lasted for about 15 days, from August 22 to September 5, is the largest in volume, or about 61 million m 3 . The lava bed that formed in the eruption from May 29 to June 22 is the third largest, or about 45 million m 3.
Evidence of magma continuing to flow from depth into the accumulation zone beneath Svartsengi
Deformation measurements in the Svartsengis area continue to show small changes between days. It indicates that the inflow into the magma accumulation area under Svartsengi is comparable to the flow from the volcanic eruption.
Between measurements by the Norwegian Institute of Natural Sciences, from November 23 to 28, the average lava flow from the eruption was about 11 m 3 /s. Based on the SO 2 measurements made yesterday, it is estimated that the lava flow then was 7 - 8 m 3 /s. Therefore, it can be roughly estimated that the current lava flow is somewhere between 5-10 m 3 /s.
Risk assessment updated
The Icelandic Meteorological Office has updated the risk assessment due to the eruption and it is valid until 15:00 on December 3. Overall risk is unchanged in all regions from the last release. The risk assessment for area 4 (Grindavík) is unchanged, but there will be one change in area 1 (Svartsengi), where the risk of gas pollution is now considered considerable, but was previously assessed as very high.
Beautiful video. I like the natural sound and that roar! Keep up the good work of sharing your videos and stay safe. Greetings from the Netherlands.
