  • I knew that I would enjoy this book when I saw that Andrew Charleson had used one of my favorite buildings, the Villa Savoie in Paris, as a seismic design case study. The earthquake engineers ’ nightmare, with its pin-like pilotis, ramps and roof garden – the epitome of the free planned International Style dwelling – it floats above the field in Poissy, giving the illusion of being on the sea.

  • Recent major earthquakes around the world have shown the vulnerability of infrastructure and the need for research to better understand the nature of seismic events and their effects on structures. As a result, earthquake engineering research has been expanding as more and more data become available from a large array of seismic instruments, large scale experiments and numerical simulations.

  • Hurricanes, floods, earthquakes, landslides and volcanic eruptions—and the devastation they inflict—are all too familiar to the countries of Latin America and the Caribbean. In the last decade, natural disasters have caused more than 45,000 deaths in the region, left 40 million injured or in need of assistance, and carried a price tag—in direct damage alone—of more than US$20 billion.1 The health sector has proven particularly vulnerable to such havoc.

  • Approaches to Disaster Management regards critical disaster management issues. Ten original research reports by international scholars centered on disaster management are organized into three general areas of hazards and disaster management. The first section includes discussions of perspectives on vulnerability and on evolving approaches to mitigation. The second section highlights approaches to improve data use and information management in several distinct applications intended to promote prediction and communication of hazard.

  • With many 'flexible' structures such as large span bridges, tall buildings, towers, cable roofs, etc., being built, the need to understand the dynamics behavior of structures has become a necessity for many engineers. The recent problems with the millinium bridge is simply another reminder. The many devastating earthquakes in many parts of the world leading to severe loss of life in densely inhabited urban areas alos has underlined the need for a fundamental understanding of structural behavior.

  • However, some scientists are working on earthquake precursors and forecasting research and this is a big challenge. Chapter in this book will be devoted to different aspects of the Earthquake Research and analysis, from theoretical advances for practical applications. The first two chapters for statistical analysis. About ten chapters in Part II focus on research precursors of earthquakes and forecasting. Some proposed new methods for early detection, as well as observations of earthquakes through the use of social sensors....

  • Natural disasters destroy more property and kill more people with each passing year. Volcanic eruptions, earthquakes, hurricanes, tsunamis, floods, landslides, fires and other natural events are becoming more frequent and their consequences more devastating. Del Moral and Walker provide a comprehensive summary of the diverse ways in which natural disasters disrupt humanity and how humans cope. Burgeoning human numbers, shrinking resources and intensification of the consequences of natural disasters have produced a crisis of unparalleled proportions.

  • The impact of an earthquake, flood or war on reproductive health can be devastating. Communities in crisis are suddenly deprived of reproductive health information and services. Access is cut off, yet needs persist, even escalate. A large number of refugees and internally displaced women will be pregnant, facing delivery under dangerous conditions; others may be victims of violence including rape. The United Nations Population Fund (UNFPA) is committed to assisting and protecting women, men and youth made vulnerable by natural disaster, armed conflict, persecution and other causes.

  • Although the vast majority of earthquakes that occur in the world each year have natural causes, some of these earthquakes and a number of lesser magnitude seismic events are related to human activities and are called “induced seismic events” or “induced earthquakes.” Induced seismic activity has been documented since at least the 1920s and has been attributed to a range of human activities including the impoundment of large reservoirs behind dams, controlled explosions related to mining or construction, and underground nuclear tests.

  • The International Year of Planet Earth (IYPE) was established as a means of raising worldwide public and political awareness of the vast, though frequently under-used, potential the Earth Sciences possess for improving the quality of life of the peoples of the world and safeguarding Earth’s rich and diverse environments. The International Year project was jointly initiated in 2000 by the International Union of Geological Sciences (IUGS) and the Earth Science Division of the United Nations Educational, Scientific and Cultural Organisation (UNESCO).

  • The threat statement, or the list of potential threat-sources, should be tailored to the individual organization and its processing environment (e.g., end-user computing habits). In general, information on natural threats (e.g., floods, earthquakes, storms) should be readily available. Known threats have been identified by many government and private sector organizations. Intrusion detection tools also are becoming more prevalent, and government and industry organizations continually collect data on security events, thereby improving the ability to realistically assess threats....

  • The study of natural catastrophe models plays an important role in the prevention and mitigation of disasters. After the occurrence of a nat- ural disaster, the reconstruction can be financed with catastrophe bonds (CAT bonds) or reinsurance. This paper examines the calibration of a real parametric CAT bond for earthquakes that was sponsored by the Mexican government. The calibration of the CAT bond is based on the estimation of the intensity rate that describes the earthquake process from the two sides of the contract, the reinsurance and the capital markets, and from the historical data.

  • By its geographical position, Mexico finds itself under a great variety of natural phenomena which can cause disasters, like earthquakes, eruptions, hurricanes, burning forest, floods and aridity (dryness). In case of disaster, the effects on financial and natural resources are huge and volatile. In Mexico the first risk to transfer is the seismic risk, because although it is the less recurrent, it has the biggest impact on the population and country. For example, an earthquake of magnitude 8.

  • As the study of natural catastrophe models plays an important role in the preven- tion and mitigation of disasters, the main motivation of this paper is the analysis of pricing CAT bonds. In particular, we examine the calibration of a parametric CAT bond for earthquakes that was sponsored by the Mexican government and issued by the special purpose CAT-MEX Ltd in May 2006.

  • Each year more than 200 million people are affected by floods, tropical storms, droughts, earthquakes, and also operational failures, wars, terrorism, vandalism, and accidents involving hazardous materials. These are part of the wide variety of events that cause death, injury, and significant economic losses for the countries affected. As demonstrated by recent events, natural and manmade hazards can affect anyone in anyplace.
