Researchers discover mechanism increasing certain earthquake magnitudes
A team of scientists has uncovered a mechanism that can amplify the magnitude of specific earthquakes by altering fault dynamics. Published in Nature Geoscience, the findings reveal how fluid interactions in fault zones contribute to larger seismic events. This discovery could improve models for predicting earthquake severity in fluid-rich areas.
MIT uncovers traces of proto-Earth in ancient mantle rocks
Researchers at MIT have identified chemical remnants of Earth's earliest form, preserved deep within the planet's mantle. The discovery reveals a potassium isotope imbalance pointing to material from 4.5 billion years ago, surviving a cataclysmic collision. This finding challenges assumptions about Earth's formative history.
Cuba commemorates Geological and Mining Workers’ Day
On October 24, Cuba marks Geological and Mining Workers’ Day. Roberto Morales, secretary of organization of the Central Committee of the Communist Party of Cuba, congratulated these workers. The commemoration highlights their role in Havana.
Breakup of supercontinent Nuna enabled complex life evolution
The breakup of the ancient supercontinent Nuna around 1.5 billion years ago reshaped Earth's surface, reducing volcanic carbon emissions and expanding shallow seas that fostered oxygen-rich environments. Scientists from the University of Sydney and the University of Adelaide link this tectonic event to the rise of early eukaryotic life. Their study challenges the notion of a stagnant 'Boring Billion' period in Earth's history.
Scientists uncover new insights into ancient microbial life
Reported by AI
A recent study has revealed groundbreaking details about microbial ecosystems from billions of years ago. Researchers analyzed ancient rock samples to uncover how early life forms adapted to extreme conditions. The findings could reshape our understanding of Earth's biological history.
