Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive treatment of earthquake hazards in Lebanon and its vicinity. A thorough review of the tectonics of the region is given alongside a re-assessment of the historical and instrumental earthquake records. Probabilistic seismic hazard analysis is undertaken and hazard maps are presented in terms of peak ground parameters as well as spectral ordinates (acceleration and displacement). Owing to their significance to the economy of Lebanon, the three cities of Beirut, Sidon and Tripoli are subjected to site-specific earthquake hazard assessment. The maps provided are the best available estimates of seismic hazards in Lebanon and are recommended for use in risk assessment. Also, the basis and framework for similar studies in the Levant are given. The rigorous and pragmatic approach adopted by the authors renders the book accessible to design engineers and researchers alike.

Available in PDF, EPUB and Kindle. Book excerpt: This study concentrates on the evaluation of seismic hazard of Lebanon to determine the most probable ground motion parameters needed for seismic design. The seismic hazard was evaluated using probabilistic methods of hazard analysis. Potential sources of seismic activities that affect Lebanon were identified and the earthquake recurrence relationships of these sources were developed based on instrumental and historical seismological records. The computations were performed using a specially written computer program of hazard analysis in which design peak ground accelerations were estimated at the nodes of a 10 by 10 Km mesh covering the entire Lebanese territory. The results were presented in terms of iso-acceleration maps showing contour lines of horizontal peak ground acceleration corresponding to 0.1 probability of exceedance in different time spans (50, 100, and 500 years). Charts were also provided for the capital city Beirut showing the variation of average return periods and probability of exceedance versus peak ground acceleration for 50, 100, and 500 years. Based on the outcome of hazard analysis, it was recommended to consider Lebanon as one seismic zone with horizontal peak ground acceleration equal to 0.15g, where g is the gravitational acceleration. The corresponding zone is similar to Zone 2A of the Uniform Building Code of the United States (UBC, 1991).

Download or read book Seismotectonics and Seismic Behaviour of the Lebanese Restraining Bend written by Tony Nemer and published by . This book was released on 2005 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dead Sea Transform Fault (DSTF) extends for about 1000 km between the Gulf of Aqaba and southeast Turkey. It bends rightward and forms the Lebanese restraining bend (LRB). Within this bend, the main fault splays into 5 fault branches, of which only the Yammouneh fault is through-going and represents the main continuation of the DSTF across the bend. In this work, we study the 4 auxiliary fault branches from the structural, active tectonic and palaeoseismic view points, in order to understand their tectonic behaviours and assess their seismic hazard.The Roum fault is associated with fresh fault scarps and pressure ridges which attest for recent coseismic ruptures. A palaeoseismic excavation shows a complex fault zone with several rupture strands, and a minimum of 4 large seismic events with surface ruptures during the last ~10000 years. The last seismic event along it was most probably to the 1 January 1837 (Ms ~ 7.1) earthquake.The Rachaya and Serghaya faults are associated with the presence of different geomorphic expressions that are direct manifestations of young surface-rupture displacements. Palaeoseismic investigations along both faults show their current faulting activity and indicate the earthquake recurrence along them. They constitute a single fault system that is tectonically active and found associated with the 30 October - 25 November 1759 (Ms ~ 6.6 and 7.4) earthquake sequence.Little and intermittent faulting is found along the Hasbaya fault that does not show signs of tectonic activity that affects Late Pleistocene deposits.The LRB constitutes a positive flower structure along the DSTF, whereby a structural interconnection of the different faults and folds takes place together with block movements.A deterministic seismic hazard evaluation of the study area indicates that future earthquakes will have drastic ground-motion effects.

Book excerpt: After fifteen years of reconstruction in a relatively peaceful environment spanning the years 1990 to 2004, Lebanon has experienced successive violent political events resulting from complex entangled internal and external struggles. The Syrian crisis and its political, economic and demographic consequences on Lebanon have increased these tensions. This atlas sheds light on these new challenges and adds new data that complete the analyses already published in the Atlas du Liban. Territoires et société (Atlas of Lebanon. Territories and Society) released in 2007 by the same research team. Some of its components are included in this edition. Beyond the international regional crisis and the population movements, it takes into account Lebanon’s socio-economic dimensions, the environmental issues linked to uncontrolled urbanization and to natural risks, as well as conflicts due to local territorial management. This atlas is the result of a collaborative endeavor between French and Lebanese researchers. It uses a geographical approach that puts in the foreground a spatial analysis of social and natural phenomena. Public sources are scarce in Lebanon, especially at the local scale. They are sometimes less reliable and difficult to access. It is particularly the case for the Lebanese census data, conversely data are abundantly available on the refugees population, which is less known than the population of refugees. International data help compare Lebanon to its neighbors. Thematic data produced by some ministries are helpful to provide a detailed view regarding specific domains. Analyses processed on aerial and satellite images have produced essential data on urbanization and environment. Local thematic fieldwork surveys have provided additional data. The book consists of seven chapters. The first one deals with the territorial state-building seen in the light of regional geopolitics, and emphasizes internal violence and the reemergence of militias and armed groups that fight each other and the state army. Lebanon is once again perceived as a territory divided between multiple allegiances. The second chapter is devoted to the analysis of population dynamics, despite the lack of reliable data whose sources are subject to discussion. It includes analyses of internal population flows, the Lebanese diaspora, and the assessment of Syrian refugees’ influx. The third chapter shows the fragility of the Lebanese economic model. Its dependency on foreign investments and on...

This book was released on 2010 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents the results of a study undertaken to evaluate the implications of a newly discovered fault system and associated geological and seismological findings on the seismic hazard of Lebanon and the already established seismic zone parameters used by the engineering community for earthquake design. This is particularly critical since the fault is located at a close proximity to the major cities and economic centers of the country.--Similar to the seismic hazard evaluations undertaken earlier, the seismic hazard was assessed using probabilistic methods of hazard analysis. The potential sources of seismic activities that affect Lebanon were identified, taking into account the newly discovered fault system, and the earthquake recurrence relationships of these sources were developed from instrumental seismology data, historical records, and earlier studies undertaken to evaluate the seismic hazard of neighboring countries.--The sensitivity of the results to different assumptions regarding the seismic sources in the Lebanese segment and the choice of the attenuation relationship were evaluated. Maps of peak ground acceleration contours, based on 10 percent probability of exceedance in 50 years, 100 years and 500 years time spans, were developed. Further, a probabilistic seismic hazard analysis was conducted for twelve Lebanese cities, and the results are presented in the form of plots of probability of exceedance versus peak ground acceleration for 50, 100 and 500 years exposure time. In addition the level of ground shaking was assessed for the same twelve cities in the event a maximum magnitude earthquake would occur on any of the major faults within Lebanon.

Book excerpt: Containing the papers from the 11th International Conference on Computer Simulation in Risk Analysis and Hazard Mitigation 2018, this book will be of interest to those concerned with all aspects of risk management and hazard mitigation, associated with both natural and anthropogenic hazards. Current events help to emphasise the importance of the analysis and management of risk to planners and researchers around the world. Natural hazards such as floods, earthquakes, landslides, fires and others have always affected human societies. The more recent emergence of the importance of man-made hazards is a consequence of the rapid technological advances made in the last few centuries. The interaction of natural and anthropogenic risks adds to the complexity of the problems. The included papers, presented at the Risk Analysis Conference, cover a variety of topics related to risk analysis and hazard mitigation.
Download or read book Seismic Risk Assessment of Existing Building Structures in Lebanon written by Nadine Rajeh El-Khoury and published by . This book was released on 1997 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given its location on the seismic map of the region, and its history of seismic events. Lebanon can be classified as a seismic prone country. Today, almost all structures are being designed without taking into account earthquake loading conditions, which leads to the assumption that current structures in Lebanon are unsafe for seismic loading. In this study, the weaknesses in the current design and construction practices of reinforced concrete building structures in Lebanon with regard to seismic performance were examined. The resistance and ductility of ideal model buildings with design and structural systems similar to those used in Lebanon was examined. Several design parameters were investigated, namely, building height, shear walls distribution in the building, and the design ground acceleration. Three design accelerations were considered in the analysis, namely, 0.15g. 0.2g and 0.3g. For each of the parameters above, the following design requirements were evaluated: (i) strength requirements, (ii) dimensional limitations of the beams and columns, (iii) "strong column-weak beam" design strategy, (iv) strength of beam-column joints, and (v) ductility of the beams and slab. Based on the results of this study it was concluded that the structural member sizes in building structures in Lebanon are inappropriate for seismic loading conditions under high seismic risk. The strength requirements for the slabs and beams were unsatisfactory for both moderate and high seismic risk. All columns satisfied the strength requirements, except for edge columns under high seismic risk. Shear walls may encounter flexural failure under strong ground shaking. The shear strength of the beams and walls was satisfactory for all parameters considered. On the other hand, the shear strength requirements for columns were unsatisfactory except for exterior columns when the direction of earthquake is parallel to their long plan dimension. Under severe ground shaking, the beams and slabs are not ductile enough to ensure adequate energy absorption and dissipation capability. The beam-column joints may fail under earthquake loading, due to their inadequate shear resistance to earthquake forces and the lack of confinement reinforcement throughout the depth of the joint. Finally, the strong column-weak beam design concept was met.

Book excerpt: In the winter of 1811-12, a series of large earthquakes in the New Madrid seismic zone-often incorrectly described as the biggest ever to hit the United States-shook the Midwest. Today the federal government ranks the hazard in the Midwest as high as California's and is pressuring communities to undertake expensive preparations for disaster. Disaster Deferred revisits these earthquakes, the legends surrounding them, and the predictions of doom following in their wake. Seth Stein clearly explains the techniques seismologists use to study Midwestern quakes and estimate their danger. Detailing how limited scientific knowledge, bureaucratic instincts, and the media's love of a good story have exaggerated these hazards, Stein calmly debunks the hype surrounding such predictions and encourages the formulation of more sensible, less costly policy.
