Seismic waves travel in all the directions and used to determine the magnitude of an earthquake. There are 3 types of seismic waves that move in different directions.
1. P wave: It is the fastest of all three waves that travel through the interior of the earth and are compressive waves. 
2. S wave: Secondary waves generally follow the P waves and travel through the interior of the earth but are shearing waves. 
3. Surface wave: This is the slowest of all three waves that moves close to the surface of the ground. 
These waves affect the movement of other materials when they are passing through the interior or surface of the earth. 
P waves can move through the solid rocks and even liquids. S waves do not travel through the  liquids such as water and molten magma. Surface waves causes shaking of the ground and do not go deep inside the earth.

Answer: Literally everywhere. Having an at least basic level of science helps you in day-to-day situations. For example, cooking. Not only is it crucial to understand the chemical and physical processes when cooking, you should also understand the complexity of how these micro and macromolecule exchange processes affect you and your body. Another prime example is your health, or human processes. You might not realize this, but your body is a plethora of complex, interconnected systems and networks that work hard 24/7 to maintain homeostasis (keep you alive). Understanding how our human physiques conduct themselves helps us gain the knowledge to be able to stay alive.
