Main Body
Variation across earth's interior based on time of arrival of seismic waves signify cence creation of Hazard zonation maps and understanding Earth's geological composition. This leads to understanding level of destruction and thus taking preventive measures. Test: Japan as it is on Earth's highly seismic plate has created earthquake resistant houses. Additionally, surface waves like love & Rayleigh also contribute in systematic investigations however, seismic investigation are limited in giving information about Earth's interior structure & its complexity.
