A study in Geodesy and Geodynamics used satellite radar to examine the November 2025 Hayli Gubbi eruption in Ethiopia’s Afar Depression. Researchers combined NISAR’s left-looking radar with Sentinel-1’s right-looking observations to reconstruct three-dimensional ground movement. Although the eruption occurred at Hayli Gubbi, the strongest deformation was detected at Erta Ale, where the summit crater partially collapsed and the ground sank inward. Modeling linked this to two shallow dikes beneath Erta Ale, both about 1 km deep. The event also reactivated nine nearby faults. Compared with a larger eruption earlier in 2025, the November event was more localized and relied mainly on shallow magma storage.

Researchers at the Max Planck Institute for Intelligent Systems and Carnegie Mellon University have unveiled a breakthrough technology that allows for highly accurate 3D motion capture using only standard video cameras, eliminating the need for expensive, specialized hardware and the iconic skin-tight motion capture suits covered in reflective markers. They named their system MAMMA – Markerless Accurate Multi-person Motion Acquisition. This system is capable of accurately capturing human motion without the need for markers, making it easy and cheap for everyone to create high-end animations and virtual avatars.
