Web10 Apr 2024 · Even though Earth has been around 4.5 billion years, and geology is not a new field, our understanding of the planet’s innards is still immature, Hansen said. … WebSeismic waves recorded at increasing distances from an earthquake indicate that seismic velocities gradually increase with depth in the mantle (exceptions: see Low Velocity Zone and 670 km Discontinuity above). However, at arc distances of between about 103° and 143° no P waves are recorded. Furthermore, no S waves are record beyond about 103°.
