Uplift of the area continues and its speed is now greater than it had been before the last eruption. The interpretation is that magma continues to accumulate in a storage area underground below.
The Icelandic Met Office (IMO) estimates that the rate of magma inflow into the magma chamber under Svartsengi is now 4-6 cubic meters per second based on geophysical modelling of the observed deformation.
It is estimated then the latest eruption from May 29 to mid June 2024 evacuated around 13-19 million cubic meters of magma from the magma chamber. The results of modeling calculations indicate that if the current rate of magma inflow from deeper sources remains unchanged, the magma chamber under Svartsengi will hold a similar volume as before the eruption on May 29 in 3 to 6 weeks from now.
As of today, it is therefore likely that a new eruption will start in the coming weeks and months.
Here we see a graph, based on geophysical model calculations, showing the evolution of magma accumulation and the estimated total amount of magma in the magma chamber under Svartsengi from October 25, 2023 and its evolution between events. The red dots show the position since May 30, 2024.
