Magma accumulation beneath Svartsengi approaches 23 million cubic meters since the last eruption - 3.3.2026

Magma has been accumulating beneath Svartsengi for around 210 days, making this the longest continuous accumulation period since the eruptive episode along the Sundhnúkur crater row began in December 2023. If magma accumulation continues at the same rate, it can be expected that by next week the total volume of magma accumulated since the last eruption will be the largest recorded between eruptions since the start of the eruptive episode.
