LFE at 50: Impacts of Earthquake Reconnaissance Past, Present, and Future

Celebrating the 50th anniversary of the EERI Learning from Earthquakes (LFE) Program, the one-day Technical Program on April 12 will underscore major achievements in seismic safety around the world that were only possible because of observations made and data captured through reconnaissance efforts over the past 50 years.The 2023AM Program Committee is led by Co-Chairs Laurie Johnson and Jonathan Stewart. Below is an overview of the program.

Note: Registration for the technical program also includes access to the Welcome Reception and Turkey/Syria Earthquake Sequence Special Session on Tuesday evening.

Taking Measure: How Earthquake Reconnaissance Has Evolved Over Fifty Years

Extreme events, such as tornadoes and fires, test buildings and infrastructure in ways and on a scale that cannot be easily replicated in a laboratory. Therefore, actual disasters and failure events provide important opportunities for scientists and engineers at the National Institute of Standards and Technology (NIST) and elsewhere to study these events, and improve the safety of buildings, their occupants, and emergency responders. The lecture will provide an overview of the disaster research conducted at NIST and informed by strategic plans developed by national disaster statutory programs: Disaster and Failure Studies (DFS) Program, National Earthquake Hazard Reduction Program (NEHRP), and National Windstorm Impact Reduction Program (NWIRP). The lecture will highlight how the metrology of disasters has evolved since the Learning from Earthquakes (LFE) Program was established fifty years ago by the National Science Foundation, a NEHRP agency. The lecture will also provide an overview of how the advancement of tools (e.g., interview/survey instruments, GIS, data management, etc.) and technology (e.g., lidar, GPS, drones, etc.) in seismic reconnaissance missions has enabled scientists and engineers to better quantify the physical and social impacts of earthquakes on communities. The lecture will commemorate the multidisciplinary approach to learning from disasters, directly borne out of the LFE Program.

Spatial Correlation in Ground Motion Intensities: Measurement, Prediction, and Seismic Risk Implications

Jack Baker, Stanford University

The amplitude of ground shaking during an earthquake varies spatially, due to location-to-location differences in source features, wave propagation, and site effects. These variations have important impacts on infrastructure systems and other distributed assets. This presentation will provide an overview of efforts to quantify spatial correlations in amplitudes, via observations from past earthquakes and numerical simulations. Regional risk analysis results will be presented to demonstrate the potential role of spatial correlations on impacts to the built environment. Traditional techniques for fitting empirical correlation models will be discussed, followed by a proposal for new techniques to account for soil conditions and other site-specific effects. Prospects for future opportunities in this field will also be addressed, including the role of numerical simulations and advanced risk assessment.
