What is a seismic safe building?
No building is seismic safe. No building is earthquake proof. However, there are steps that can be taken to make buildings more earthquake resistant. Concrete buildings made without rebar will collapse in an earthquake. Concrete buildings and concrete block buildings in Guatemala that hold up in earthquakes are those that use a lot of rebar. It is also important to use metal straps to tie the roof to the walls. The straps are inexpensive, but they maintain the integrity of the building. The roof should have cross pieces.
Can you create an island out of concrete then build a city on it?
No because if there were to be an earthquake, it would be gone and concrete is not very stable foundation.
How do the cables of a suspention help it withstand an earthquake?
Through the main cables being anchored in huge concrete blocks and the pylon towers resting on bedrock.
How does architecture affect our lives?
The greatest contribution of Greek Architecture is the use of the columns, which we still use today. They also contributed the development of limestone, marble, and concrete as a building material.
Name three methods of improving building's safety before an earthquake?
lets give you 5: firstly, you can put cross braces on all around the building. Cross braces are metal supports that allow the building to twist and sway when there are seismic waves. The second way to protect a building against buildings is by having rubber shock absorbers in the foundations of the building. They absorb the tremors from the earthquake, preventing it from collapsing. Another way is by having a big box of concrete at the top of the building which is controlled by a computer. It slides to the other direction of the earthquake force, preventing to from collapsing. An example of using this method is the Taipei 101: If you install automating shutters in your building, you would save lots of people from being injured or even dying. This is because when the glass from the windows breaks, they could fall on people. The automatic shutters go over the windows, prevent the glass from flying everywhere. Also, if you have an open space, it can be a safe area for people to come when evacuated. These are also known as assembly points.

What are the strongest building materials to protect from earthquakes?
Base isolation pads can be built to absorb the vibrations to withstand earthquakes. Building materials can be reinforced to withstand an earthquake. For example, wood can be reinforced with bolts to make the wood more secure.
Why do some earthquake with small magnitude result in more death than earthquake with lager magnitude?
There is no direct correlation between deaths and magnitude. It all depends on the earthquake's location in terms of population areas, and depth.A 6.5 magnitude quake directly under a large city, might kill 50,000, but an 8.5 magnitude quake situated slightly further away from the city might only kill 500 or so.
How is concrete used in building a skyscraper?
Concrete is used in building a skyscraper to help make it wind proof and able to support its own weight. The building can also be earthquake safe when rods are put through the concrete to make it stable.
Why was the Chilean earthquake of magnitude 8.8 less deadly than the Haitian magnitude 7 earthquake?
Chile is a well developed country with a history of earthquakes. As such the Chilean building regulations incorporate rules specifying that buildings must be earthquake resistant and just as importantly, these rules are enforced.Haiti on the other hand is a much poorer country where the construction regulations are not well enforced. This meant that in Haiti poor building practices were followed - e.g.insufficient steel reinforcement in concrete, the use of cheap or poorly sourced aggregates which reduce the strength of concrete or the construction on poor founding materials without the requisite foundation engineering which all acted to increase the damage caused by earthquake. As such the buildings were not earthquake resistant and so a significant number collapsed leading to the significantly higher loss of life in what was a lower magnitude earthquake.For more information on the two earthquakes and on the factors that effect the damage an earthquake can cause, please see the related questions.
Why did so few people die in the recent 1989 san fransisco quake?
California now has a good building code. It is more expensive to make a house or a building so it will not fall down in an earthquake but it is possible. Concrete is not a strong material. Adding rebar to concrete makes it much stronger. In earthquake zones much more than the average amount of rebar must be added. The roof must be attached to the building rather than just placed on top. That makes the building a solid unit. Thus, unlike Haiti, the buildings in California are built to withstand an earthquake. If the building does not fall down on a person, the person will not be killed by a falling building! If the infrastructure is not harmed, it will not be followed by a cholera epidemic.
Is a modern twelve story reinforced concrete condo building safe in an earthquake?
A local building inspector may be able to answer your question.
What kind of material are industrial buildings made of?
Industrial buildings can be made from all types of materials, some include metal, reinforced steel, wood, concrete and many other products. The materials a building is made from depends on what the building is going to be used for, a very tall commercial building would be made out of steel and concrete so that it can withstand the wind and other pressure from being high in the air. A building that is used for construction work would be mostly made out of concrete so it could withstand heavy machinery.
Is an event like an earthquake a concrete noun?
Correct, earthquake is a concrete noun.
What has the author Arnaldo T Derecho written?

How can earthquake with a moderate magnitude have a high intensity?
The location of the earthquake's epicentre in relation to centres of population is important. A high magnitude earthquake that occurs far from a populated area will do less damage than a lower magnitude earthquake in very close proximity to a populated area.Secondly, ground motion and the amplitude of seismic waves is strongly dependent on the medium through which they travel. Seismic waves in hard rock masses (e.g. granite) have lower amplitudes than those that travel through soft ground such as sediments and so a building constructed and founded on hard rock is less likely to be damaged. As such a lower magnitude earthquake affecting structures founded on softer sediments may ultimately cause more damage than a higher magnitude earthquake affecting structures founded on hard rock.Further to this, sediments tend to undergo a process known as liquefaction during earthquakes which makes them behave as a liquid rather than a solid meaning they are very poor at supporting the load imposed by the building (they lose the majority of their bearing capacity) making it even more probable that the building will be damaged.The construction techniques employed in the area and the enforcement of applicable construction codes or standards will affect how destructive an earthquake is (earthquake resistant designs will obviously reduce the damage caused by seismic waves, on the other hand, in countries or areas where poor building practices are followed - e.g. insufficient steel reinforcement in concrete, the use of cheap or poorly sourced aggregates which reduce the strength of concrete or the construction on poor founding materials without the requisite foundation engineering will all act to increase the damage caused by earthquakes).
