EARTHQUAKES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following affects the amount of destruction caused by earthquake vibrations?
A
the nature of the material on which structures are built
B
the design of structures
C
the intensity and duration of the vibrations
D
All of the above
Explanation: 

Detailed explanation-1: -When an earthquake strikes, the intensity of earthquake shaking determines the severity of damage. In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristics-particularly height.

Detailed explanation-2: -Earthquakes can result in the ground shaking, soil liquefaction, landslides, fissures, avalanches, fires and tsunamis. The extent of destruction and harm caused by an earthquake depends on: magnitude. intensity and duration.

Detailed explanation-3: -Ground shaking is the vibration of the ground during an earthquake. The shaking triggers other hazards such as liquefaction and landslides. Most earthquake damage results from the seismic waves passing beneath buildings, roads, and other structures.

Detailed explanation-4: -The effects from earthquakes include ground shaking, surface faulting, ground failure, and less commonly, tsunamis.

Detailed explanation-5: -In the process of breaking, vibrations called “seismic waves” are generated. These waves travel outward from the source of the earthquake along the surface and through the Earth at varying speeds depending on the material through which they move.
