In recent years, a number of research efforts conducted through the National Center for Earthquake Engineering Research (NCEER) have focused on assessing seismic hazard and vulnerability in the Central United States. These multi-year, coordinated multi-investigator research efforts culminated in two loss estimation demonstration projects for Memphis (Shelby County), Tennessee, that evaluate losses associated with buildings and lifelines, respectively. While conducted independently, these two loss estimation studies share similar approaches, such as the emphasis on using detailed local data. Furthermore, the significance of the projects derives not only from the advances made by individual investigators, but also from the innovations developed in synthesizing the various studies into a coordinated loss estimation effort. This paper discusses the NCEER buildings and lifelines loss estimation projects with emphasis on methodological advances and insights from the loss estimation results.

Strong Ground

A new seismic hazard model, the fourth national model for Canada, has been devised by the Geological Survey of Canada to update Canada's current (1985) seismic hazard maps. The model incorporates new knowledge from recent earthquakes (both Canadian and foreign), new strong ground motion relations to describe how shaking varies with magnitude and distance, the newly recognized hazard from Cascadia subduction earthquakes, and a more systematic approach to reference site conditions. Other new innovations are hazard computation at the 2% in 50 year probability level, the use of the median ground motions, the presentation of results as uniform hazard spectra, and the explicit incorporation of uncertainty via a logic-tree approach. These new results provide a more reliable basis for characterizing seismic hazard across Canada and have been approved by the Canadian National Committee on Earthquake Engineering (CANCEE) as the basis of the seismic loads in the proposed 2005 edition of the National Building Code of Canada.Key words: seismic hazard, earthquake, probability, uniform hazard spectrum, maps, Cascadia subduction, strong ground motions, uncertainty, CANCEE, National Building Code of Canada.

Vulnerability Functions

Seismic risk in regions of low seismicity is evaluated using the UK as an example. This involves quantifying the seismic hazard and also the vulnerability functions for a range of typical structures. Predictions are made as to the effects of a range of specific earthquakes occurring under two existing areas of the UK. By integrating the hazard and vulnerability seismic risk has been calculated in terms of cost and fatalities and compared to those arising from other types of hazard. Recommendations are made as to when, and in what form, seismic considerations may be necessary.

Since 1990, an increased number of locations for the Lower Mainland of British Columbia has been listed in the Table of Climatic Data in the Supplements to the National Building Code of Canada. While for most of the new locations the seismic acceleration and velocity zones are shown as Za = Zv = 4, Ladner is listed with Za = 5, leading to significant cost increase in the construction of certain types of buildings. Although the zonal value is formally correct, it is suggested that such discrimination is not justified by the current precision of seismic hazard estimation.The Canadian National Committee on Earthquake Engineering does not address regional variances of this nature; it is, therefore, further suggested that a regional committee should decide on an equitable solution, with due consideration of estimated probabilities of exceeding ground motion parameters, and the precision of these estimates. Some of the background and details aiding such a decision are discussed. Key words: seismic hazard, acceleration, seismic zones, earthquake design, Vancouver acceleration.

Urgent Computing

<p>Seismic wave propagation is currently computationally prohibitive at high frequencies relevant for earthquake engineering or for civil protection purposes (up to 10 Hz). Developments of computational high-performance computing (HPC) infrastructures, however, will render routine executions of high-frequency simulations possible, enabling new approaches to assess seismic hazard - such as Seismic Urgent Computing (UC) in the immediate aftermath of an earthquake. The high spatial resolution of near-real time synthetic wavefields could complement existing live data records where dense seismic networks are present or provide an alternative to live data in regions with low coverage. However, time to solution for local near-field simulations accounting for frequencies above 1 Hz, as well as availability of substantial computational resources pose significant challenges that are incompatible with the requirements of decision makers. Moreover, the simulations require fine tuning of the parameters, as uncertainties in the underlying velocity model and in earthquake source information translate into uncertainties in final results. Estimating such uncertainties on ground motion proxies is non-trivial from a scientific standpoint, especially for the higher frequencies that remain an uncharted territory. In this talk we wish to address some of these key challenges and present our progress in the design and development of a prototype of a Seismic UC service. In the long run, we hope to demonstrate that deterministic modelling of ground motions can indeed in the future contribute to the short-term assessment of seismic hazard.  </p>
