Between Two Earthquakes

This handbook addresses three areas of concern for the museum administrator concerning the protection of historic buildings, monuments, and archaeological sites located in seismic areas. It proposes pre-disaster measures such as taking accurate and complete documentation (photogrammetry is discussed in one of the 13 appendixes), risk awareness, planning, maintenance and inspections, etc. Second, when an earthquake strikes, the immediate emergency steps necessary to protect life and property are indicated; and after the earthquake, the strengthening of valuable cultural property (based on the Modified Mercalli Intensity Scale, also in an appendix) should be included in the general program of prevention maintenance along with the repairs discussed in detail applicable to each architectural element, and to the site as a whole.

Earth’s fractured geology is visible in its fault lines. It is along these lines that earthquakes occur, sometimes with disastrous effects. These disturbances can significantly influence urban development, as seen in the aftermath of two earthquakes in Messina, Italy, in 1908 and in the Belice Valley, Sicily, in 1968. Following the history of these places before and after their destruction, this book explores plans and developments that preceded the disasters and the urbanism that emerged from the ruins. These stories explore fault lines between “rural” and “urban,” “backwardness” and “development,” and “before” and “after,” shedding light on the role of environmental forces in the history of human habitats.

This is a discount Black and white version. Some images may be unclear, please see BCCampus website for the digital version.This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in courses because textbooks have become too expensive for them to buy. But the real inspiration comes from a fascination for the spectacular geology of western Canada and the many decades that the author spent exploring this region along with colleagues, students, family, and friends. My goal has been to provide an accessible and comprehensive guide to the important topics of geology, richly illustrated with examples from western Canada. Although this text is intended to complement a typical first-year course in physical geology, its contents could be applied to numerous other related courses.

Our understanding of earthquakes and faulting processes has developed significantly since publication of the successful first edition of this book in 1990. This revised edition, first published in 2002, was therefore thoroughly up-dated whilst maintaining and developing the two major themes of the first edition. The first of these themes is the connection between fault and earthquake mechanics, including fault scaling laws, the nature of fault populations, and how these result from the processes of fault growth and interaction. The second major theme is the central role of the rate-state friction laws in earthquake mechanics, which provide a unifying framework within which a wide range of faulting phenomena can be interpreted. With the inclusion of two chapters explaining brittle fracture and rock friction from first principles, this book is written at a level which will appeal to graduate students and research scientists in the fields of seismology, physics, geology, geodesy and rock mechanics.

In 1999, two earthquakes occurred in the Istanbul-Marmara region of Turkey and the Athens-Corinth region of Greece, and an increased risk of further events caused great concern among the earth science community. This book presents and discusses the latest results from studies of the Izmit-Düzce and Athens earthquakes and assesses the data that are available and relevant to the geology, seismology, tectonics, geodesy and other fields related to earthquake studies and to evaluate earthquake hazard potential.

This thesis adopts the relative back-projection method to dramatically reduce “swimming” artifacts by identifying the rupture fronts in the time window of a reference station; this led to a faster and more accurate image of the rupture processes of earthquakes. Mitigating the damage caused by earthquakes is one of the primary goals of seismology, and includes saving more people’s lives by devising seismological approaches to rapidly analyze an earthquake’s rupture process. The back-projection method described in this thesis can make that a reality.
