Episodes 2006年第2期29卷 145-145页

作者： R. L. Kovach Niu Zhijun Cambridge University Press 2004268pp. UK hardback ￡60.00. ISBN*** School of Hydropower and Information engineering Huazhong University of Science and Technology Wuhan 430074 CHINA

In recent decades the science of seismology, in particular the study of individual earthquakes, has expanded dramatically. A seismologist can look for evidence of past earthquakes in the material remains that have been excavated by archaeologists. This book examines the interplay and implications of archaeology, myths and legends, and past earthquake and volcanic occurrences in the Americas. It looks at earthquakes in Mexico, the Maya Empire, Costa Rica, the Bahamas, Columbia, Peru, Chile, California, the North American Cordillera, and Central North America, covering the regions where important earthquakes have occurred and speculaing on their impact and historical role.
