Seismic waves are generated by movement along:
a. oceans
b. glaciers
c. faults
d. fractures

I would believe it is the Faults. On earth there are techtonic plates and where one plate and the other meet up - it is called the fault line. And when two plates i.e. collide, brush against each other etc. , then earthquakes, volcanos and tsunamis can be formed. In terms of seismic waves, Earthquakes create seismic waves. Therefore the answer should be c. Faults
