How can ground shaking and liquefaction can cause building to collapse?

Liquefaction is when the ground soil is mixed with the ground water, causing the soil to become less stable and lose its strength. As it loses its strength, the building will sink into the soil and tilt, in some cases collapse.

What causes liquefaction?
in the bedrock (soil/ground) with loose sediments.
How can homes and other structers be protected from liquefaction?
Homes and other structures can be protected from liquefaction by being anchored to a rock below the soil. Liquefaction happens when structures are built on soft ground.
How does the type of rock and soil affect the amount of shaking and damage from an earthquake?
The amplitude of seismic waves is dependant 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 on granite is less likely to be damaged. Soils can undergo a process known as liquefaction during earthquakes which can greatly reduce their ability to support imposed loads by building foundations. This can ultimately lead to structural damage or collapse. This typically occurs in cohesionless soils (typically those with a higher content of larger grains such as sand sized clasts) which have water in the pore spaces, and are poorly drained. For more information on liquefaction, please see the related question.
What is the shaking of the ground that precedes an earthquake?
Tremors
How high on the Richter scale would kill someone?
The energy in the Richter scale will not of itself kill anyone. Indeed if you are outside in an open area you are likely to be safe (baring cracks in the ground and liquefaction. It is things falling on you that will kill you and that depends on the design of the building/structure you are in. A weak earthquake in a poor building can kill you. A strong earthquake in a well built building will probably not kill you.
What process in which shaking the ground causes soil to act like a liquid?
Liquidfication
What else forms on the edges of tectonic plates?
ground shaking, displacement, liquefaction, tsunamis and landslides
What caused the ground the shake so strongly and how is shaking recorded?
The Liquefaction dryed up and turned to clay
What causes liquefaction?
in the bedrock (soil/ground) with loose sediments.
What kinds of damage can an earthquake do on the structures in the built environment?
Several factors determine the structural damage from an earthquake including, the proximity to active earthquake faults; the building construction (type of building, foundation, materials used, and quality of workmanship); the local site conditions (type and condition of soil, slope of the land, and fill material); and the geologic structure of the earth beneath the structure.
How can homes and other structers be protected from liquefaction?
Homes and other structures can be protected from liquefaction by being anchored to a rock below the soil. Liquefaction happens when structures are built on soft ground.
What is the importance of a foundation when a tower or tall building such as a skyscrapper is being constructed?
a foundation is a huge hole in the ground where a building goes into and if it didnt have any foundations it would either collapse or sink into the ground
Do people get hurt by an earthquake?
Yes, people can get hurt by an earthquake. The shaking of the ground can cause buildings and structures to collapse or suffer significant damage, leading to injuries or fatalities. Additionally, falling debris, landslides, and tsunamis triggered by earthquakes can also cause harm to people.
How can homes and other structures be protected from liquefaction?
Liquefaction is caused by soil types in poor drainage areas which are shaken by earthquakes. This causes small pockets of openings. Before construction, the soil must be tested and a plan to ameliorate the cause - soil and/or water drainage - as well as to consider the best sort of foundation for the building.
What is another threat to people during an earthquake besides ground shaking?
Buildings and bridges collapsing, fires as a result of collapse, loss of water and electricity from damage to utilities, etc.
What might happen if there was an earthquake near a mountain?
Shaking, ground rupture, landslides, avalanches, fires, liquefaction, floods, tsunamis, destruction, death - you get the point.
Can lord of d effect be negated by ground collapse?
Ground Collapse does not negate anything.
