Earthquakes pose myriad dangers to heritage collections worldwide. This book provides an accessible introduction to these dangers and to the methodologies developed at the Getty and other museums internationally for mitigating seismic vulnerability. Conceived as a primer and reference, this abundantly illustrated volume begins with an engaging overview of explanations for earthquakes from antiquity to the nineteenth century. A series of chapters then addresses our modern understanding of seismic events and approaches for mitigating the damage they cause to heritage collections, covering such subjects as earthquake measurement, hazard analysis, the response of buildings and collections to seismic events, mount making, and risk assessment; short sections by specialists in seismic engineering complement the main text throughout. Readers will find a range of effective seismic mitigation measures, from simple low-cost approaches to complex base-isolation techniques. In bridging the gap between seismologists and seismic engineers, on the one hand, and collections care professionals, on the other, this volume will be of interest to conservators, registrars, designers, mount makers, and others involved in the management and care of collections in museums and other cultural institutions.
