The shifting weights placed in the roofs of some earthquake-resistant buildings are called "mass dampers" or "tuned mass dampers." These devices help reduce the motion of the building during an earthquake by shifting their weight in response to the building's movements, thereby dampening vibrations and enhancing stability. This engineering technique is designed to protect the structure and its occupants from the effects of seismic activity.
The ground and buildings shake primarily due to seismic activity, such as earthquakes, which occur when tectonic plates shift and release energy. This sudden release generates seismic waves that propagate through the Earth, causing vibrations. Additionally, human activities like construction, mining, or explosions can also create localized shaking. These vibrations can lead to structural damage or even collapse if the intensity is strong enough.
Limestone buildings at busy road junctions are more exposed to pollutants like car emissions and traffic vibrations, which accelerate weathering. In comparison, buildings in the country are often subjected to fewer pollutants and less traffic-related wear and tear, resulting in slower weathering.
Earthquake resistant buildings are necessary to protect people's lives and reduce property damage during seismic events. These buildings are designed to withstand the forces and vibrations caused by earthquakes, preventing collapse and reducing the risk of injury or death. Investing in earthquake resistant buildings is crucial in regions prone to earthquakes to ensure the safety and well-being of occupants.

yes they feel wave vibrations
Vibrations are typically not visible to the human eye because they occur at a level that is too small or rapid for our eyes to detect. While we can observe the effects of vibrations, such as objects moving or sound being produced, the vibrations themselves are not visible.
When vibrations traveling through an object match the object's natural frequency, a phenomenon known as resonance occurs. This causes the amplitude of the vibrations to increase significantly, which can lead to unwanted effects such as structural damage or failure. Resonance is commonly observed in musical instruments, buildings, and bridges.

Two negative effects are the noise and the vibrations; caused by the speed.
In spectroscopy, active vibrations refer to those that cause a change in the dipole moment of a molecule, while Raman active vibrations cause a change in the polarizability of a molecule. Both types of vibrations can be observed in spectroscopy, but they have different effects on the properties of the molecule being studied.
This works on the same phenomenon as the shock absorbers that the cars have. Also, it would be same as a spring.
