Seismic waves are the waves that transport energy away from the focus of an
earthquake. Seismometers, such as the one shown here, measure the
shaking of the Earth as a result of earthquakes. Swaves, or surface waves,
move through the surface crust like a water wave. What property is most
likely to make earthquake Swaves most damaging?
A. Waves with a short period
OB. Waves with a large amplitude
OC. Waves with high frequency
D. Waves with a high speed
