Why do structures located on thick, soft sediment, especially water-saturated or artificial fill, suffer
  much greater damage than structures built on bedrock? What will be an ideal response?

Question 2

Explain the differences between the magnitude and the intensity of an earthquake, in terms of how
  many intensities and magnitudes a single, given earthquake can have. What will be an ideal response?

Answer to Question 1

Surface waves cause this material to shake, lose its cohesiveness, and collapse. Sometimes they mix
with water and move like a fluid, in a process called liquefaction.

Answer to Question 2

An earthquake can have only one magnitude, but it will have different intensities in different locations.
