New Algorithm Uses Fiber Optic Cables to Improve Earthquake Detection Globally
Researchers have developed an algorithm that converts fiber optic cables into seismic sensors, improving earthquake detection and early warning systems. The method integrates fiber optic and traditional seismometer data, overcoming challenges in earthquake monitoring. The technology could also help detect seismic activity in volcanoes and glaciers....

Updated World Magnetic Model Predicts Magnetic North Pole’s Shift
On December 17, the National Centers for Environmental Information and the British Geological Survey released an updated version of the World Magnetic Model, designed to predict Earth's magnetic field changes over the next five years. The update is crucial for ensuring the accuracy of navigation systems, including satellite and smartphone applicati...

Earth’s Inner Core Might Be Slowing Down and Changing Shape, New Study Reveals
Research suggests Earth’s inner core, a metal sphere within the molten outer core, is slowing its spin and reshaping. Seismic wave analyses from earthquakes reveal discrepancies indicating deformation on the core’s surface or changes in rotation. John Vidale, a geophysicist from the University of Southern California, presented these findings, s...

Study Reveals Ultra-Low Velocity Zones May Be More Common in Earth's Mantle Than Previously Thought
A new study published in AGU Advances has unveiled intriguing findings about ultra-low velocity zones (ULVZs) in Earth's mantle, suggesting these mysterious features might be more widespread than previously thought.ULVZs, which are known to dramatically slow seismic waves by up to 50%, have long been associated with volcanic hotspots such as Hawaii...
