The Svartsengi magma chamber reached 24 million cubic meters on Friday — no eruption yet, but the Icelandic Met Office says the question is when, not if.
BBC Science covered the update as a monitoring story with no urgency.
Volcanology X is tracking the inflation data daily, noting that the magma volume exceeds the threshold of every prior Reykjanes eruption.
The Icelandic Meteorological Office reported Friday that the magma reservoir beneath Svartsengi on the Reykjanes Peninsula has reached an estimated 24 million cubic meters, exceeding the pre-eruption volume of every previous event in the current eruptive sequence that began in 2021. [1]
Ground uplift near Grindavík continues at approximately 1 centimeter per day. The town remains evacuated. No eruption has occurred, but the volume exceeds every prior threshold.
