  • In the last three decades, the historical earthquake investigation became an outstand- ing source of information in seismology. The rigorous interpretation of known or newly discovered historical documents from public and private archives, including military and religious documents, press reports, correspondences, publications, etc., brings new light on the effect of past earthquakes and contributes to the assessment of their characteristics. Historical documents are nowadays examined in the frame of modern methodologies and new approaches applied in the study of individual earthquakes.

  • For the earthquake motion level 1, the elastic limit the value of a structure is usually adopted seismic activity. For Level 2 earthquake motion, on the other hand, the limit value that a structure does not collapse or repair through the seismic activity depends on the importance of intended structure. Level 2 earthquake motions are used for verification is based on the records of strong motion seismograms obtained from the Hyogoken Nanbu earthquake and the other, and seismic waveform types are assigned according to the ground....

  • A database is any collection of related data. The files on your hard drive and the piles of paper on your desk all count as databases. What distinguishes a relational data- base from other kinds of databases is the mechanism by which the database is orga- nized—the way the data is modeled. A relational database is a collection of data organized in accordance with the relational model to suit a specific purpose. Relational principles are based on the mathematical concepts developed by Dr. E. F.

  • 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.

  • The George E. Brown, Jr., Network for Earthquake Engineering Simulation (NEES) is a collaboratory for integrated experimentation, computation, theory, databases, and model-based simulation in earthquake engineering research and education intended to improve the seismic design and performance of the U.S. civil and mechanical infrastructure. Administered by the National Science Foundation (NSF), NEES is mandated to be operational by September 30, 2004.

  • In practice, however, earthquakes generate stronger ground motion than Level 1 but not exceeding Level 2 can occur in service life of a structure. In current seismic design, consideration was not given directly to changes in activities and risks to the seismic motion through time and the importance of adopting effective methods of repair and reinforcement. These factors can not be implemented fully into account by simply checking the elastic limit or reparability limits or structural collapse of a Level 1 or 2 earthquake motion forces based on current seismic design....

  • The Naval Facilities Engineering Command seeks to expand the technology base upon which future shore facilities are founded. An important area in which a new design approach is being developed is in the management and understanding of those characteristics of earthquake and explosively generated foundation motions that damage or destroy Naval equipment. This report is a part of the design method development. Specifically, it documents and offers a new method of shock and response spectrum computation.

  • We live in an era with unparalleled opportunities to practice disease prevention based on knowledge of the earth environment. Although globally distributed early warning systems can monitor physical hazards such as earthquakes and tsunamis, chemical hazards on the other hand—whether actual or potential and natural or anthropogenically induced—remain difficult to accurately identify in time and space. Such hazards often have lengthy asymptomatic latency periods before disability or disease becomes evident....

  • Since a modeled loss trigger mechanism takes other variables into account that can affect the value of the losses, the pricing of a hypothetical CAT bond with a modeled-index loss trigger for earthquakes in Mexico is also examined in this paper. This new approach is also fundamentally driven by the desire to mini- mize the basis risk borne by the sponsor, while remaining non-indemnity based.

  • 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.
