Reducing the Risks of Nonstructural Earthquake Damage (FEMA E-74) Training, 8:00am-12:00pm (Tuesday, March 7)

Instructor: Mike Griffin
Cost: $35 (covers A/V and venue fees)
Location: Salons A & B

Failure of nonstructural components—which includes all those components that are not part of the structural system, such as architectural, mechanical, electrical, and plumbing systems, as well as furniture, fixtures, equipment, and contents—have accounted for the majority of earthquake damage in several recent U.S. earthquakes. In many cases, businesses, schools, hospitals, and other organizations had to spend excessive time and dollars for clean-up and repair due to nonstructural failures; therefore impeding continued operations and rapid recovery. Nonstructural component failures can impede safe evacuation, delay rescue, and cause additional hazards, such as fire following an earthquake. Training on FEMA E-74, Reducing the Risks of Nonstructural Earthquake Damage, covers the sources and types of nonstructural earthquake damage, as well as effective methods and guidance for reducing the potential risks of injury and property loss from future earthquakes. Questions about this training can be directed to Veronica Cedillos at vcedillos@atcouncil.org

Post Earthquake Reconnaissance Workshop (PERW); 1:00 - 5:00PM (Tuesday, March 7)

Organizers: EERI’s Student Leadership Council and the EERI Learning from Earthquakes Program
Cost: $30
Location: Salons A, B, C

This workshop will provide an overview of conducting post-earthquake reconnaissance and a demonstration of EERI field data collection tools. The workshop will include a field exercise that will give participants the opportunity to practice making reconnaissance observations for structural or geotechnical damage scenarios. EERI members who complete this training will have a practical introduction to post-earthquake reconnaissance and information about opportunities to participate in future reconnaissance efforts.

Why the Pacific Northwest is Different, and Why it Matters
Earthquake Lexicon 101: are we on the same wavelength?
The Pacific Northwest (PNW) hosts a range of seismic regimes and hazards, including large urban areas and populated coastlines at risk for a great subduction-zone earthquake. The region’s scarcity of damaging earthquakes, and infrequent disasters of any kind, generate challenges in awareness, preparedness, and meaningful investment in resilience across sectors. In dealing with these challenges, it is imperative that we have a common understanding of the terminology that we use in earthquake matters. This session will combine a contextual orientation and a panel interacting with the audience with the objective of more effective communication.

Location: Salons F - I

2017 marks the 40th anniversary of the National Earthquake Hazards Reduction Program (NEHRP) established by Congress with its passage of the Earthquake Hazards Reduction Act in 1977. NEHRP authorized federal government involvement and funding for a long-term nationwide program to reduce risks to life and property from earthquakes. With the most recent reauthorization in 2004, the National Institute of Standards and Technology (NIST) was designated as the lead federal agency for the program. Other NEHRP agencies are the Federal Emergency Management Agency (FEMA), National Science Foundation (NSF), and the United States Geological Survey (USGS). A federal Advisory Committee for Earthquake Hazard Reduction (ACEHR) was also authorized in 2004 to be widely representative of the stakeholder community and to regularly assess the effectiveness of NEHRP and its management, coordination, implementation, and activities.

While changes have occurred in program details over time, the four basic NEHRP goals remain unchanged:

  • Develop effective practices and policies for earthquake loss reduction and accelerate their implementation.
  • Improve techniques for reducing earthquake vulnerabilities of facilities and systems.
  • Improve earthquake hazards identification and risk assessment methods, and their use.
  • Improve the understanding of earthquakes and their effects.

During the past 40 years, the federal government has been a key organizer and funder of a wide array of programs related to understanding seismic hazards, developing guidelines, codes and standards for structures and lifelines, enhancing federal, state and local earthquake preparedness and mitigation, and conducting fundamental research in the earth sciences, engineering, and social sciences. This session will celebrate the key accomplishments of NEHRP, recognize the refined focus federal programs are now developing, and underscore the programs and needs requiring a uniform national perspective and sustained federal involvement in order to progress nationwide seismic resilience.

Presenter: Lucy Jones, USGS Retired
Title: "Life Safety in the City: There is more to life than not being crushed"

Location: Salons A - E

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.

Case Studies in Seismic Design of Buildings, 1:45PM – 3:15PM (Concurrent Session)

Moderator: Sandra Hyde, International Code Council

Speakers: Mark Tobin, KPFF; Jay Love, Degenkolb Engineers; Bob Glasgow, and Keith Porter, SPA Risk and the University of Colorado

Location: Salon F

In regions struggling to upgrade buildings to a level of life safety sufficient to prevent collapse during a large earthquake or maintain function, what choices are made when designing SFRSs and non-structural components to code or to a higher performance? Three case studies will consider choices made by engineers based on local conditions for ground motion, potential for long duration shaking and consideration of whether life safety design is sufficient for economic and community needs. Then the cost of building to a higher performance will be discussed. The following questions are considered: what goals are required, how is immediate use defined for design goals, and will back-up utilities be available when the building performs as expected?

Speakers: Mike Harryman, Oregon State Resilience Officer; Oregon Governor's Office; Brad Avy, Director, State Geologist, DOGAMI; Doug Toomey, University of Oregon; Andrew Phelps, Director, Oregon Emergency Management

Location: Salons G - I

“Resilience” is a ubiquitous term, but most applications are broad, conceptual, or both. This session offers specific examples of how Oregon has approached the challenge of seismic hazards on a statewide level, with distinctly finite resources. The 2013 release of the Oregon Resilience Plan (ORP) charted a course for public and private organizations, as well as state action. The relatively recent awareness of Oregon’s range of seismic hazards, brought forth by a group of technical policy champions, offered a path toward (greater) resilience. This session includes a panel, and focuses on statewide impacts, and includes information on some of the most pressing issues: earthquake hazard and risk assessments, development of the Pacific Northwest’s earthquake early warning system, and state continuity of government. Specific case studies from local agencies, state agencies, planners and researchers will be presented. The panel sessions will explore gaps, goals and next steps to advance earthquake resilience.

Long-Duration Shaking in Structural Design/Response, 1:45PM – 3:15PM (Concurrent Session)

Moderator: Nicholas Rillstone, KPFF Consulting Engineers

Speakers: Peter Dusicka, Portland State University; Jeffrey Berman, University of Washington

Location: Salon F

Many of the guidelines and recommendations for the design of earthquake resistant structures were developed based on knowledge and experience gained from earthquakes occurring in Southern California. These events tend to be short in duration and contribute mainly to the response of short period structures. Recent subduction earthquakes have subjected structures to ground shaking with much longer duration. Earthquake generated hazards in the Pacific Northwest have the potential to cause long duration shaking and have a significant contribution to the response of long period structures. Geotechnical and structural design implications will be discussed as they pertain to long duration shaking for both short and long period structures.

Speakers: Joseph Wartman, University of Washington; Kent Yu, SEFT Consulting; Michael Germeraad, Association of Bay Area Governments (ABAG); Tom O’Rourke, Cornell University

Location: Salons G - I

Lifeline systems provide fundamental services for society, including water and waste-water, power, fuel, transportation, and communication. Lifeline systems are often designed independently at the system level, yet, they rely on other lifeline systems to operate. When one system fails, it can trigger failures in other systems.

This session will explore lifeline system vulnerabilities, interdependencies, and potential impacts from different types of earthquake hazards, including liquefaction and landslides. Discussion will include how interdependencies of lifelines have impacted service delivery, response, and recovery in earthquakes. A case study of lifeline interdependencies in the San Francisco region will be presented. A holistic research framework to improve earthquake-resilient lifelines developed by NIST will be discussed. A panel discussion will focus on how engineers, lifeline owners and operators address dependencies on lifelines; how to better understand lifeline interdependencies; and identify needs to improve the reliability of critical lifeline service after major earthquakes. The program will include:

Advocating for NEHRP Reauthorization, 3:45PM – 5:15PM (Concurrent Session)

Organizers/Moderators: EERI Public Policy and Advocacy Committee, Laura Dwelley Samant, Chair

Panelists: Craig Davis, Los Angeles Department of Water and Power; Robert Pekelnicky, Degenkolb Engineers; Glenn Rix, GeoSyntec Consultants; Barry Welliver, BHW Engineers; Jay Wilson, Clackamas County Disaster Management.

Location: Mt Hood (2nd Floor)

The National Earthquake Hazards Reduction Program (NEHRP) was launched forty years ago with the goal of coordinating and supporting the work of key federal agencies to reduce the nation’s earthquake risk. In the decades since, the program has led to dramatic reductions in risk and advancements in knowledge, but much work remains to be done. However, today the program needs revitalization. Its Congressional authorization expired in 2009. While funding for the program continues, unfortunately, it has not kept up with inflation and the Presidential requests and appropriations granted by Congress have failed to meet program needs.

A variety of roadblocks stand in the way of NEHRP reauthorization now, including lack of a legislative champion, disagreement among professional organizations on priorities and funding needs, conflicting perspectives from NEHRP agencies, and lack of a coordinated and consistent effort to advocate for NEHRP’s reauthorization. The decades worth of NEHRP Advisory Committee reports clearly state the issues at hand.

EERI strongly believes that Congress needs to reauthorize a revitalized NEHRP program and raise the agency appropriation levels to meet the program needs. Similarly, the Presidential budget needs to request appropriate funding to support this critical work. But given today’s realities, NEHRP may need to evolve to be effective. The session will probe how the program can be reenergized and whether and how it should change.

Panelists will present brief “lightning talks” with a range of perspectives from around the US, followed by audience discussion and interaction. The goal of this session is to plot a path forward to advocate for effective federal leadership of the nation’s earthquake programs. Following this session, EERI’s Public Policy and Advocacy Committee will shape the ideas heard in the session into clear talking points and a strategy that can be used by EERI members and partners to shape and support the next generation of NEHRP legislation.

EERI/FEMA NEHRP Graduate Fellow Presentations, 8:30AM – 9:00AM

Moderator: David Friedman; EERI President

Speakers: Christine Beyzaei, University of California, Berkeley and Nasser Marafi, University of Washington

Location: Salons F - I

Beyzaei: “Liquefaction Resistance of Silty Soils: An Investigation in Christchurch, New Zealand,” State-of-practice liquefaction triggering procedures have been shown generally to work well across much of Christchurch when compared with post-earthquake observations from the 2010-2011 Canterbury earthquake sequence. However, there are important cases where liquefaction assessment methods indicate significant liquefaction-induced ground failure should have occurred, yet none was observed. Post-earthquake reconnaissance investigators noted that these discrepancies were concentrated in areas of the city known to have silty soil conditions.

This presentation explores discrepancies between surface manifestations of liquefaction and estimates using state-of-practice liquefaction assessment procedures at silty soil sites in Christchurch, New Zealand. Research topics to be presented include: (i) field sampling and laboratory testing to evaluate cyclic response of the silty soils, (ii) depositional geologic effects, and (iii) site characterization to capture thin-layer stratigraphy and groundwater table effects. These topics are discussed in terms of how they may affect liquefaction manifestation at a site. Limitations of current simplified liquefaction triggering procedures at stratified, silty soil sites are delineated.

Marafi:”Impacts of an M9 Cascadia Subduction Zone Earthquake on Structures Located in Deep Sedimentary Basins,” The Cascadia Subduction Zone (CSZ) is capable of producing long-duration, large-magnitude earthquakes (up to magnitude 9) that could severely affect buildings and infrastructure in the Pacific Northwest (PNW). In addition, deep sedimentary basins are expected to amplify ground-motion intensity which underlie several cities in the Puget Sound region. The effects of long-duration and basins are poorly understood for the CSZ, because no ground-motion recordings are available for large-magnitude earthquakes in this region. To compensate for the paucity of recorded subduction events in the PNW, suites of simulated M9, CSZ ground motions are used to study their effects on archetypical structures in the PNW region. The severity of these ground motions is quantified in terms of several intensity measures that quantify ground-motion duration and spectral shape, and are compared with recordings from Japan with similar site and source characteristics. Finally, the performance of these archetypes is evaluated in terms of collapse risk, and appropriate design recommendations which account for long-duration effects and basin amplifications are proposed.

Title: "Seismic Hazard Analysis and Capturing Uncertainty – Just How Uncertain Should We Be?"

Location:  Salons F - I

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.

In the absence of major recent earthquakes in the Pacific Northwest, we take our lessons from other regional incidents, exercises, and major events elsewhere. Our final session will offer specific examples of what is already in progress to enhance resilience, as well as some resources available to public and private sectors. The session will incorporate live audience polling on paths forward.
