Earthquake engineering is an area of multi-disciplinary study. It is a long established area mainly within the scope of structural engineering and geotechnical engineering, but can include construction materials as well. Structural engineers are responsible for the design of new structures and the redesign and upgrade of existing structures in order to minimize the damage caused by earthquakes and thus save lives.
