They have created agencies. Those agencies created rules and regulations to stop the flow of pollution, etc.
The types of seismic waves are confined at the surface are
- Rayleigh waves
- Love waves
<u>Explanation:</u>
Rayleigh wave are having the motion of retrograde particle which is confined to the vertical plane of the motion. Love wave are having the motion which is transverse which is confined to horizontal plane of the motion. If we talk about other mentioned waves than P waves, S- waves all travel in different pace from slow to fastest. S-waves travel in slow pace whereas p-waves are called the fastest. Disperse waves also travel in a decent speed
