10 Questions
What are the three main categories that effects of earthquakes can be divided into?
Ground failure, indirect effects, ground shaking
Which of the following is NOT an indirect effect of earthquakes?
Ground failure
What type of ground failure involves the movement of the ground surface at a location where geological fissures or faults slip slowly or suddenly?
Surface faulting
Which type of ground failure involves rocks breaking through to the surface due to relative movement on both sides of a fault?
Surface faulting
Why is sudden movement in ground failures considered more damaging?
It is associated with ground shaking

Long wavelengths and small crest-to-trough height
What causes seiches, earthquake-induced waves in enclosed bodies of water?
Long-period seismic waves resonating with water oscillations
