Nature
Increased urban populations and the use of new construction systems whose resistance to earthquakes has not been sufficiently studied have led to an increase of the earthquake hazard. Also, in spite of the considerable achievements of theoretical and experimental research into the origin and the nature of earthquakes the dynamics of soils, the response of structures and soil-construction interaction, the results are not yet generally reflected in existing building codes and regulations.
Claim
Buildings in earthquake-prone areas that do not take into consideration the effects of seismic forces may be considered death traps.
