EERI releases updated functional recovery paper with policy options

EERI is pleased to release an updated white paper titled, “Functional Recovery: A Conceptual Framework with Policy Options,” leading the earthquake risk reduction field in a new way of thinking about resilience and formulating responsive policy solutions. Download the white paper here.

This version supersedes our white paper dated July 24, 2019, and includes two parts and a new executive summary. The first part contains the full language of the conceptual framework that was previously released, with a few slight revisions and updates.

The new second part explores how legislatures and government agencies at the federal, state, and local level can develop or implement policies for functional recovery. The policy options vary in scale and focus, however, the white paper considers ideas for buildings and infrastructure, both new and existing. EERI recognizes that the normal processes for developing design standards can and should be used and that there are also interim options available to policymakers. 

In this updated paper, EERI explores a diverse suite of policy possibilities organized into the following four categories:

  1. Legislation and regulations that require designing and planning for functional recovery, in addition to safety.
  2. Interim programs that encourage designing and planning for functional recovery.
  3. The development of technical consensus, specifically in the form of standards that set objective design criteria and planning strategies for achieving specified functional recovery times.
  4. The development of policy consensus, specifically in the form of building code provisions and infrastructure regulations that assign, with local customization, acceptable functional recovery times to buildings and lifeline infrastructure systems based on their role in supporting various community functions.

The paper will inform a new NIST-FEMA working group mandated by recent national legislation and others considering new functional recovery standards and practices. You can expect to hear more about this at the EERI Annual Meeting and National Earthquake Conference in March 2020.

Papers of recipients must be judged to have made a significant impact on the profession, to provide a significant advance in the state-of-the-art or understanding of a particular topic, to be of exceptional technical quality with concise and informative illustrations and to be well written for a broad audience.

Paper Abstract: The Central Italy earthquake sequence initiated on 24 August 2016 with a moment magnitude M6.1 event, followed by two earthquakes (M5.9 and M6.5) on 26 and 30 October, caused significant damage and loss of life in the town of Amatrice and other nearby villages and hamlets. The significance of this sequence led to a major international reconnaissance effort to thoroughly examine the effects of this disaster. Specifically, this paper presents evidences of strong local site effects (i.e., amplification of seismic waves because of stratigraphic and topographic effects that leads to damage concentration in certain areas). It also examines the damage patterns observed along the entire sequence of events in association with the spatial distribution of ground motion intensity with emphasis on the clearly distinct performance of reinforced concrete and masonry structures under multiple excitations. The paper concludes with a critical assessment of past retrofit measures efficiency and a series of lessons learned as per the behavior of structures to a sequence of strong earthquake events.

Exciting plenary at NEC2020 explores framing earthquake hazard conversation

NEC Bommer Jones Email yellow

Don’t miss out on an exciting plenary session at the 2020 National Earthquake Conference and 72nd EERI Annual Meeting, “From Earthquakes Big to Small: How to Frame the Earthquake Hazard Conversation!” Register today to take advantage of the early-bird rate!

This dynamic and timely session features Dr. Julian J. Bommer, Senior Research Investigator at Imperial College London and the 2020 EERI/SSA Joyner Lecturer, and Dr. Lucy Jones, founder of the Dr. Lucy Jones Center for Science and Society, followed by a facilitated Q&A session.

Drs. Bommer and Jones will explore the science and impact of smaller earthquakes and how to frame conversations to stakeholders about considering and planning for earthquakes of various scales. More often than not, planning and mitigating for earthquakes focus on earthquakes with large magnitudes, extensive damage, and far-reaching societal impacts. Discussing only large-scale earthquakes, however, can limit how the public, policymakers, and critical decision-makers perceive risk and take preventative actions. 

More specifically, Dr. Bommer will discuss how the occurrence of some low-magnitude earthquakes in recent years has caused unexpected levels of damage and particularly by the heightened concern regarding earthquakes of anthropogenic origin. By examining case studies, a global analysis of small-to-moderate magnitude earthquakes, and structural damage caused by the smallest magnitude earthquakes, the lecture provides insights regarding if and when smaller earthquakes should be a concern, as well as on the modeling challenges related to hazard and risk.

Dr. Jones will then expand upon the scientific basis for consideration of small earthquakes by exploring what we can learn from risk perception science and how that should impact how we speak about both large and small earthquakes. Disasters can be on a personal scale, for those whose home or livelihood are lost, or on a societal scale when infrastructure damages result in cascading impacts that interrupt the economic prosperity of a community. They create different motivators for action at both the personal and societal levels.

Learning from Earthquakes

EERI coordinates reconnaissance efforts for the M6.4 Durres, Albania Earthquake

EERI is actively responding to the November 26 M6.4 Durres, Albania Earthquake. The Learning From Earthquakes (LFE) Executive Committee met on December 1 to determine EERI’s response. Based on information provided in the Virtual Earthquake Reconnaissance Team (VERT) report and by other members in the field, the LFE committee decided that EERI is best positioned to serve in a coordination role for this earthquake. 

EERI has been in close contact with several colleagues who have conducted or will conduct reconnaissance. We coordinated a call on December 10 to provide an opportunity for teams to share observations and discuss plans. EERI will be developing a joint report on the earthquake with contributions from those in the field. EERI has established an earthquake page on the LFE website where several reports are posted. 

Preliminary observations from the reports include:

  • The most common building damage pattern observed was shear “X” cracking and out-of-plane failure of hollow clay tile nonstructural walls. This type of damage was especially common in taller (8 to 12 story) buildings, but it was also exhibited in shorter (2 to 7 story) buildings. This type of building has been built in Albania since 1990, and many of the buildings were built in the last few years. Code enforcement in design and construction was limited during the period in which many of these buildings were constructed. It is a common building type in Albania. (personal observations from Chiara McKenney,M.EERI,2011)
  • Sand boils and liquefied material were observed near the sites of collapsed buildings in the coastal area of Durres. (Newsletter of Environmental, Disaster, and Crisis Management Strategies)
  • Several collapsed reinforced concrete buildings were observed. Most contained irregularities including soft stories, torsional irregularities, or discontinuous columns that may have contributed to collapse. (personal observations from Chiara McKenney,M.EERI,2011)

More information about the earthquake impacts can be found in the reports available on the LFE website:
