Icelandic Fissure Finally Erupts
The position of the eruption and wind conditions are favorable. No one is in immediate danger, local officials said.
Eruption Now Unlikely Near Icelandic Town
Scientists and local authorities had been tracking the eruption’s precursors for weeks and evacuated residents. Then the magma stalled.
Seafloor Shapes on the Flanks of Mid-Ocean Ridges Linked to Magma Supply
New research suggests the source of morphologic variation on mid-ocean ridges might be deeper than scientists thought.
Some High-Threat Volcanoes Are Severely Understudied
Scientists have little understanding of where magma is stored along the Cascade Volcanic Arc or how its volcanoes could affect population centers.
Rift-to-Ridge: Mid-Atlantic Ridge Segments Imprinted During Rifting
A new seismic study shows that magmatism along the eastern North American rift margin was segmented, and that rift discontinuities influence formation of fracture zones along the Mid-Atlantic Ridge.
Uncovering Mantle Heterogeneities Beneath Drifting Continents
Computational models of the composition and volumes of magmas during continental rifting evolution provide clues on the heterogeneities of the deep melting mantle.
La tercera es la vencida para el Fagradalsfjall de Islandia
La región volcánica que hizo erupción en 2021 y 2022 después de más de 7 siglos de estar dormida, lo está haciendo de nuevo.
Third Time’s the Charm for Iceland’s Fagradalsfjall
The volcanic region, which erupted in both 2021 and 2022 after more than 7 centuries of dormancy, is at it again.
How to Find a Volcanic Diamond Mine
New 3D modeling illustrates the mechanism behind the intriguing volcanic eruptions that bring diamonds to the surface.
