Precursors to eruption

Ingression of magmatic gas into a geothermal aquifer generated cyclical deformation and primed the system for the 2021 Fagradalsfjall eruption, Iceland, according to a catalogue of 39,500 precursory earthquakes combined with a poroelastic model. The image, taken on the sunny evening of May 8th 2021, shows new black lava covering the bottom of the Geldingadalur valley releasing sulfury gasses while the crater emits volcanic gasses to the atmosphere.

Editorial

  • Meeting climate targets will require considerable carbon dioxide removal in addition to emission cuts. To achieve this sustainably, a range of methods are needed to avoid adverse effects and match co-benefits with local needs.

  • Flood basalts are connected to Earth’s most extreme environmental crises, yet warming is sometimes observed before surface eruptions. Modelling reveals that a complex buildup of basalt intrusions into the crust releases enough CO2 to cause this pre-eruptive warming.

  • Tree restoration is a popular approach to mitigating climate change, but its hydrological impacts are often overlooked. Tree restoration increases evaporation, as well as increasing downwind precipitation due to enhanced moisture recycling. Our study shows that these combined effects can affect regions’ wetness or dryness, streamflow and water availability.
