Because they knock buildings down. People are bothered when buildings fall onto them.
Earthquakes shift plates in the earth some times causeing building to knock down buildings or cause cracks , sometimes minor sometimes major,
The first waves to hit are primary waves. Primary waves are seismic waves that compress and stretch the ground. P waves, or primary waves, can wreck buildings and can move straightforward through solids and liquids.
Seismic waves affect us because they are what causes the motion from an earthquake that destroy buildings and such. The three types of seismic waves are surface waves primary waves also called P-waves and secondary waves also called S-waves.
A seismic activity is an earthquake... An earthquake is when the tectonic plates (under ground) clash together, which causes an earthquake. Earthquakes can be very small or huge depending on where the country is. They can kill thousands of people, knock down buildings and create huge cracks in the ground. They are measured on a Richter scale. :)

It's used to knock down buildings. Big ball suspended from a cable on a wrecker.
Anywhere from nothing at all, to the world as you know it is destroyed ... including you. Mostly they knock down buildings.
S waves are typically more destructive than P waves because they have a greater amplitude and can cause more shaking of the ground. Additionally, S waves are responsible for generating most of the damage associated with earthquakes, such as building collapses and landslides.
P waves (primary waves) are the first waves generated by an earthquake and travel faster than other seismic waves. These waves push and pull on structures in a back-and-forth motion, causing buildings to move horizontally. While they may not cause as much damage as other seismic waves, such as S waves or surface waves, P waves can still contribute to structural damage and shaking of buildings during an earthquake.
The buildings were temporary, with construction and materials that could not withstand Chicago winters. The one exception was the Fine Arts Building, which eventually was rebuilt as today's Museum of Science & Industry.
No, ultrasonic waves cannot knock people out. Inaudible ultrasonic waves are often used in medical imaging and cleaning processes, but they do not possess the ability to induce unconsciousness in humans.

The seismic waves affect tall buildings more. It is because shaking may cause them to collide.
