GPS technology detects Japan earthquake and tsunami

The video explains how GPS signals from satellites interact with the atmosphere and how these interactions can be visualized. It highlights the disturbances in the upper atmosphere caused by an earthquake and tsunami, showing how different types of waves, such as Rayleigh, acoustic, and gravity waves, propagate. The alignment of these atmospheric disturbances with ocean tsunamis suggests a causal relationship, offering potential improvements for tsunami warning systems by tracking these disturbances in areas lacking other detection methods.
