lowshearvelocity
Low shear velocity refers to a region within the Earth's mantle where seismic shear waves travel at a slower than average speed. This phenomenon is primarily detected through seismic tomography, a technique that uses seismic waves generated by earthquakes to image the Earth's interior. Shear waves, also known as S-waves, are seismic waves that move rock particles perpendicular to the direction of wave propagation. Their velocity is influenced by the material properties of the rock, specifically its rigidity and density.
Regions of low shear velocity are generally interpreted as areas where the mantle rock is hotter and/or
The study of low shear velocity regions is crucial for understanding mantle dynamics, plate tectonics, and
