  "account": "Scientists studying ground movements beneath volcanoes in Ethiopia have gained new insights into magma activity using satellite radar data. A study in Geodesy and Geodynamics analyzed the November 2025 eruption at Hayli Gubbi, a volcano within a volcanic zone where three tectonic plates are pulling apart. By combining radar views from NASA-ISRO's NISAR mission with observations from Europe's Sentinel-1 satellites, researchers were able to reconstruct three-dimensional ground movement measurements at centimeter scale. The strongest deformation was observed at nearby Erta Ale, where sinking and inward movement suggested magma draining from two shallow dikes approximately 1 km underground. This pattern was linked to the partial collapse of Erta Ale's summit crater and the formation of two new collapse pits at Hayli Gubbi. The researchers identified nine previously inactive faults that had been reactivated by the stress changes associated with the eruption. The study highlights how combining observations from different satellite missions can provide a more complete understanding of magma pathways and eruption-related faulting, aiding in monitoring and hazard assessment of volcanic rift zones.",
  "summary": "Magma moving beneath a volcano can make the ground rise, sink or shift sideways. Measuring these changes gives scientists clues about where magma is stored and how it travels. A study published in Geodesy and Geodynamics used satellite radar to examine the November 2025 eruption of Hayli Gubbi in Ethiopia's Afar Depression. Hayli Gubbi and nearby Erta Ale are separate volcanoes within the same…",
