Earthquakes have taught us much about our planet's hidden structure and the forces that have shaped it. This book explains how observing networks transformed an instant of panic and confusion into a field for scientific research, turning earthquakes into natural experiments at the nexus of the physical and human sciences.

Winner of the Book Prize of the Forum for the History of Science in America from the History of Science Society In 1906, after an earthquake wiped out much of San Francisco, leading California officials and scientists described the disaster as a one-time occurrence and assured the public that it had nothing to worry about. California Earthquakes explains how, over time, this attitude changed, and Californians came to accept earthquakes as a significant threat, as well as to understand how science and technology could reduce this threat. Carl-Henry Geschwind tells the story of the small group of scientists and engineers who—in tension with real estate speculators and other pro-growth forces, private and public—developed the scientific and political infrastructure necessary to implement greater earthquake awareness. Through their political connections, these reformers succeeded in building a state apparatus in which regulators could work together with scientists and engineers to reduce earthquake hazards. Geschwind details the conflicts among scientists and engineers about how best to reduce these risks, and he outlines the dramatic twentieth-century advances in our understanding of earthquakes—their causes and how we can try to prepare for them. Tracing the history of seismology and the rise of the regulatory state and of environmental awareness, California Earthquakes tells how earthquake-hazard management came about, why some groups assisted and others fought it, and how scientists and engineers helped shape it.

For nearly three decades, the J. Paul Getty Museum has played a leading role in the development of seismic mitigation for museum collections. Contributors to this volume--ranging from museum conservators, mount makers, and historical archaeologists to seismologists and structural engineers--discuss and illustrate a wide variety of earthquake-mitigation efforts for collections, from the simple and inexpensive to the complex and costly. The book's essays examine the techniques applied to large collections and to small house museums, to exhibition cases containing objects as well as to monumental works of art and historical structures. Approaches range from securing and restraining objects to decoupling them from the ground through a variety of base-isolation mechanisms. These pioneering efforts have been developed in the face of significant challenges since, as any engineer, conservator, or mount maker who has undertaken this work can attest, a small sculpture can often be a far greater challenge to protect than a multistory building.
