Summary
Summary
In the 1999 delivery of the biennial addresses, Lomnitz (seismology, National U. of Mexico) outlines his vision for effective design. He draws on his theoretical studies of ground motion with particular reference to non-linear propagation on soft ground, and on his practical knowledge acquired from numerous field studies. The Road to Total Earthquake Safetyprovides an insight into how the lessons of real earthquakes may be utilised to ensure safe design in the next century.
Author Notes
Prof. Cinna Lomnitz is Professor of Seismology at the National University of Mexico.
