EERI Distinguished Lecture by Lucy Jones, U.S. Geological Survey: "Life Safety in the City: There is more to life than not being crushed"

The Resilience by Design program adopted by Los Angeles to address earthquake vulnerabilities brought together the earth science, earthquake engineering and public policy professions and worked with hundreds of community organizations to get approval for sweeping seismic resilience legislation. The process elucidated the disconnect between what well-informed members of the community and local governments understand about the earthquake risk and the goals and objectives of mitigation measures like building codes, and what has been implemented in most communities. Since their inception, building codes have been based on a principle that safety is the only valid concern of government. If an owner chooses to build a building that is a total financial loss, that is his prerogative but he cannot kill someone in the process. A key factor is that building codes consider buildings in isolation with impacts only on their owners and tenants. But the reality of a major earthquake is that the failure of a building impacts the whole community through economic disruption, population decreases, and cascading failures of engineered and social systems. This talk will explore a conceptual framework for creating a building code that reflects the realities of earthquake losses and the social dynamics of shared economic decisions.

William B. Joyner Lecture by Bill Lettis, Lettis Consultants International, Inc. "Seismic Hazard Analysis and Capturing Uncertainty – Just How Uncertain Should We Be?"

The earthquake engineering community and regulatory agencies are moving, at varying rates, toward risk-informed engineering decisions and design. Risk-informed decision making, in turn, requires that probabilistic seismic hazard analyses explicitly and transparently incorporate uncertainty in hazard-significant seismic source and ground motion parameters. The Earth science community, following the scientific method, often leads to publication of a “proponent” interpretation or model with little or no expression of uncertainty beyond the limits of the immediate data that were considered in the research. This practice leaves it incumbent on the PSHA analyst (often a consultant) to capture the proper range of uncertainty for a parameter based on the body of published literature or, at times, based on the analyst’s own interpretations of available data. This is an important, often critical, interface issue between the Earth science community and the engineering community. Over time, some published interpretations or models become incorporated into “common belief” and become accepted paradigms whose uncertainties are rarely challenged even when more recent data or studies no longer support (if not outright reject) the original interpretation or model.

Emerging best practice, originating in the nuclear industry, is to use a formal, structured process to capture the center, body and range of uncertainty for inputs to a hazard model. This process engages the Earth science community as resource (e.g., data) and proponent (e.g., interpretation or model) experts, and requires the PSHA analysts to consider whether full parameter uncertainties are captured within the available data or whether uncertainties ought to extend beyond the available data, expert interpretations, and current paradigms.

An overall goal of current PSHA practice ought to be the focus on capturing the full range of uncertainty, so that the next generation of PSHA, which will be constructed with more and better information, will have results that fall within today’s uncertainty limits. This presentation will address some of the issues and questions that have evolved in the assessment of uncertainty and suggestions for a path forward in improved communication of uncertainty between the Earth scientist and the PSHA practitioner.
