The 1940 Vrancea Earthquake. Issues, Insights and Lessons Learnt


Book Description

These proceedings include most of the available information on this major seismic event and its consequences. With an estimated moment magnitude of 7.7 and a heavy toll in terms of human and economic losses, it ranks as the largest intermediate-depth earthquake in Europe in the twentieth century. Nevertheless, because of the difficult conditions in the 1940s, the lessons learnt after the Vrancea earthquake were not extensively shared with the international scientific community and thus, this book fills a gap in the literature discussing the knowledge acquired after major disasters. Past experience together with current understanding of the 1940 Vrancea earthquake are presented along with the latest information on Romanian seismicity, seismic hazard and risk assessment, and seismic evaluation and rehabilitation of buildings and structures. Moreover, it includes excerpts from Romanian post-disaster reports and textbooks concerning the earthquake.

Disaster Response by Ceauşescu’s Communist Regime in Romania


Book Description

This book contains the first comprehensive history using extensive primary sources to trace the 1977 earthquake disaster response by the Ceauşescu communist regime, contextualizing its contribution to the public risk that remains in Romania's capital Bucharest. It traces a history of one authoritarian government’s disaster response linking its decisions and ultimate inactions to contemporary public risk. The book begins with a stand-alone chapter to introduce readers to twentieth-century Communist Romania and contextualize the Ceauşescu regime’s response. It provides insights into how Radio Free Europe filled the information vacuum, how the political police, the Securitate, worked as first responders, and how scientific experts debated the best course of action. It examines how the regime requested specific foreign assistance and activated its Securitate abroad to encourage such, prioritized restoration of the economy, and "encouraged" domestic cash and labor contributions in the name of recovery. The book examines how the disaster response abruptly ended, leaving thousands of structurally unsafe buildings. It explains the contemporary seismic risk and post-communist mitigation efforts to reduce it. This book will be of interest to students, researchers, and policy-makers in the fields of history, disaster studies, urban planning, politics, and those interested in communist-era Romania, Europe, and Eurasia; totalitarian and authoritarian regimes.

Seismic Behaviour and Design of Irregular and Complex Civil Structures III


Book Description

This book presents state-of-the-art knowledge on problems of the effects of structural irregularities on their seismic response. It also covers specific spatial and rotational seismic loads on these structures. Rapid progress in respective research on irregular structures and unconventional seismic loads requires prompt updates of the state of the art in this area. These problems are of particular interest to both researchers and practitioners because these are non-conservative effects compared with the approach of the traditional seismic design (e.g. Eurocode 8, Uniform Building Code etc.). This book will be of particular interest to researchers, PhD students and engineers dealing with design of structures under seismic excitations.
