Researchers found regions of the earth's crust stretching apart to form new sea floor, a process previously underestimated. The study reveals detachment faults, characterized by curved surfaces and swarms of tiny earthquakes, are common along the Mid-Atlantic Ridge.
Researchers found that the amplitude of shaking directly affects the chance of an aftershock, following an inverse power law relation. This discovery challenges the long-held assumption that aftershocks are triggered by static stress resulting from crust movement.
Researchers used experiments and mathematical modeling to understand seismic wave behavior in the lower mantle, finding that mineral grain alignment causes unusual wave behavior. The study provides a window into Earth's inner workings and is an important step toward integrating seismology and geodynamics in the lower mantle.
A new study reveals the Tibetan Plateau is approximately 13.5 million years old and has reached its maximum average height of 5 kilometers. The plateau's formation is attributed to the collision between two tectonic plates, resulting in a flat-topped spreading plateau.
