Roger D. Borcherdt

Roger D. Borcherdt is a prominent geophysicist and seismologist known for his extensive research on viscoelastic waves, site-dependent response spectra, and earthquake engineering. He has authored key works such as 'Viscoelastic Waves and Rays in Layered Media' and has contributed significantly to the methodology for design response spectra in seismic hazard analysis. His career includes affiliations with the U.S. Geological Survey and academic institutions, where he advanced the understanding of wave propagation in layered media.
