Why do buildings fall during an earthquake?

Answer 1

The amount of tension to resist breaking during a earthquake is what causes buildings to collapse. Buildings need to have the amount of tension reduced by either reinforcing or having it work with the movement of the earthquake.

Answer 2

The building will fall depending on what it build on. For example t will fall if it is built on soil , but if it is build on rocks or something solid there's a possibility it wont collapse. There might be a possibility for a building to not fall if it requires base isolating unites.

Answer 3

An earthquake sends out seismic waves that may cause the ground to shake up and down or side-to side. This can put an enormous amount of stress on buildings. Side-to-side shaking is especially damaging, as buildings are desiging to withstand the vertical stress of their own weight, but not this sideways stress or shear stress. In intense earthquakes, the ground may shift, crack, and even behave as a liquid, causing the foundations of some buildings to becomes unstable.

Answer 4

Because a building is built on the ground which supports it. The moving ground makes it topple down. Building are usually not made to move - they are made to stay. Nails and screws and things used in construction are built to stay in one place, but rapid and sudden movement that occurs in earthquakes causes these things to come loose.

Answer 5

Buildings can fall during an earthquake due to the strong shaking of the ground causing structural failure. If a building is not designed or constructed to withstand the forces of an earthquake, the shaking can cause it to collapse. Poor maintenance or age can also contribute to a building's susceptibility to failure during an earthquake.

Answer 6

it depends on how strong the structure is and how much it can handle.

Answer 7

If a building is not strong enough to fully withstand an earthquake, it will collapse either partially or entirely.
