Levees, Dams, and other technology

Earthquakes A Seismologist is a scientist who studies earthquakes How does the work of a seismologist help prevent earthquake damage?

Answer They locate areas most likely to shake during quakes, allowing people to plan safety programs and construct buildings that resist earthquake damage.
