What can engineers do to help to prevent structures from collapsing during earthquakes?
Engineers can enhance the resilience of structures against earthquakes by implementing seismic design principles, such as using flexible materials that can absorb and dissipate energy. They can also ensure proper structural reinforcement, incorporating features like base isolators and dampers to reduce movement during seismic events. Additionally, rigorous testing and adherence to updated building codes and standards are essential for ensuring that structures can withstand potential quake forces. Regular assessments and retrofitting of older buildings can further improve safety and stability.
What are some hazards associated with earthquake?
Earthquakes can cause tsunami's and destroy building. If they are power full enough they can break gas pipes and cause great fires.If you are inside of a building during an earthquake, falling debris and electrical equipment can trap, hurt, or even kill you
What types of building are very susceptible to collapsing due to earthquake waves?
Buildings that are particularly susceptible to collapsing during earthquakes include those with soft stories, which have large openings on the ground floor and lack adequate support. Unreinforced masonry structures, like older brick buildings, are also at high risk due to their inability to absorb seismic forces. Additionally, poorly designed or constructed buildings with inadequate foundations and materials can easily fail under the stress of earthquake waves. Finally, high-rise buildings without proper engineering to withstand lateral forces can experience catastrophic failures during significant seismic events.
What happens when seismic vibrations cause surface materials to liquify and behave like quicksand?
When seismic vibrations cause surface materials to liquefy, the soil loses its strength and behaves like a fluid, similar to quicksand. This phenomenon, known as soil liquefaction, can lead to buildings and structures sinking, tilting, or collapsing as the ground beneath them becomes unstable. It typically occurs in saturated, loose, granular soils during strong seismic activity, significantly increasing the risk of damage during earthquakes. As a result, the ground may appear to "flow," making it difficult for structures to remain anchored.
Can die in a hurricane?
Yes, people can die in hurricanes due to flooding, flying debris, and collapsing structures. It is important to follow evacuation orders and seek shelter in a safe location during a hurricane to reduce the risk of harm.
How are engineers using hydraulic ''tendons in buildings?
C. To protect them during earthquakes
what causes death and injuries during on earthquakes?
Most earthquake-related injuries and deaths result from collapsing walls, flying glass, and falling objects caused by the ground shaking.
What is cross bracings used for?
Cross bracings are used in construction to provide stability and strength to structures, especially in buildings and bridges. They help prevent swaying, twisting, or collapsing by distributing forces evenly throughout the structure, reducing the risk of structural failure during events such as earthquakes or high winds.
Why is fire damage a large concern during an earthquake?
Fire damage to a structure weakens the stability of the structure. Structures with fire damage are a concern during an earthquake due to their stability and the high chances of them collapsing.

Why does my house shake during earthquakes?
Your house shakes during earthquakes because the ground beneath it is moving violently due to the release of energy along a fault line. This movement causes seismic waves to travel through the Earth, shaking buildings and structures on the surface.
Is a crawl space a safe place during a tornado?
No, a crawl space is not a safe place to be during a tornado. It does not provide enough protection from flying debris and collapsing structures. It is best to seek shelter in a designated storm shelter or a basement if available.

Why were structures rebuilt to withstand earthquakes still heavily damaged during the 1994 northridge earthquake?
The 1994 Northridge earthquake revealed that many structures, despite being built to modern seismic codes, suffered significant damage due to several factors. One major issue was the intensity of the earthquake, which exceeded the design parameters anticipated by engineers. Additionally, some buildings were constructed with materials or methods that did not perform as expected under the specific conditions of the quake. Furthermore, the rapid development and retrofitting of structures sometimes led to inconsistencies in building practices and code enforcement.
What is the scale that is used to classify an describe the effects of earthquakes on structures and local damage conditions?
The scale used to classify and describe the effects of earthquakes on structures and local damage conditions is the Modified Mercalli Intensity (MMI) scale. This scale ranges from I (not felt) to XII (total destruction) and assesses the level of shaking and resulting damage experienced at a specific location during an earthquake.
Can die in a hurricane?
Yes, people can die in hurricanes due to flooding, flying debris, and collapsing structures. It is important to follow evacuation orders and seek shelter in a safe location during a hurricane to reduce the risk of harm.
Can we hear earthquakes why or why not?
No, earthquakes cannot be heard because the sound waves they produce are of very low frequency and do not travel efficiently through the air. People may sometimes hear noises during an earthquake caused by structures shaking or shifting, but these are not the actual sounds of the seismic waves.
