- Active fault line threatens world’s biggest hydropower project, Chinese geologists warn
Chinese geologists have identified an active fault line beneath the world’s largest hydropower project on Tibet’s Yarlung Tsangpo (Brahmaputra) River, warning it threatens the infrastructure of the mega-dam. The fracture in the Earth’s crust in the eastern Himalayan region could compromise the project’s stability, according to a study published in the journal Sedimentary Geology and Tethyan Geology.
- Space Lasers Show How Venezuela’s Earthquakes Reshaped the Earth’s Crust
Satellite imagery has shown how Venezuela's recent earthquakes altered the Earth's crust, revealing significant terrain shifts. The analysis used space-based lasers to measure these geological changes.
- Asteroid bombardment may have delayed Earth’s first continents
Research from Curtin University and Queensland University of Technology suggests repeated asteroid impacts during Earth's Hadean era injected heat into the planet's interior, keeping the crust hot and unstable. This delayed the formation of stable continents by preventing the crust from solidifying, according to a study published in Science.
