WebThe USGS collaborates with organizations that develop building codes (for buildings, bridges, and other structures) to make seismic design parameter values available to engineers. The design code developers first decide how USGS earthquake hazard information should be applied in design practice. WebNov 10, 2016 · The aforementioned seismic measures are used to calculate forces that earthquakes impose on buildings. Ground shaking (pushing back and forth, sideways, up and down) generates internal forces within buildings called the Inertial Force (FInertial ), which in turn causes most seismic damage. FInertial = Mass (M) X Acceleration (A).
