This short course will demonstrate software tools from the U.S. Geological Survey (USGS) for site-specific ground motion hazard analysis, and will provide an opportunity for feedback from earthquake engineering users. The most recent edition of the ASCE 7 Standard (Minimum Design Loads and Associated Criteria for Buildings and Other Structures) requires site-specific ground motion analysis for many more structures than did the prior edition. For example, site-specific hazard analysis shall be performed for structures on Site Class D and E sites with S1 greater than or equal to 0.2g, with some exceptions (see Section 11.4.8 of ASCE 7-16). The new site-specific requirements are expected to be part of the 2019 California Building Code.


Dr. Nicolas Luco

Nicolas Luco is a Research Structural Engineer with the U.S. Geological Survey (USGS) in Golden, Colorado. He serves as a liaison between the USGS National Seismic Hazard Mapping Project and the American Society of Civil Engineers (ASCE) Seismic Subcommittees for the ASCE 7 and 41 Standards, among other building code committees. Prior to joining the USGS in 2004, he was a Senior Analysis Engineer with the catastrophe risk modeling company AIR Worldwide Corporation. He earned his PhD and BS in civil/structural engineering, and an MS in statistics, from Stanford University; his MS in civil/structural engineering is from the University of California, Berkeley.




Dr. Peter Powers

Peter Powers is a research and development geophysicist at the U.S. Geological Survey. Peter started his career as a geologist and worked in both the mining and tech sectors before attending the University of Southern California, from which he received a PhD in geophysics and seismology. He began his time at the USGS in 2008 as a Global Earthquake Model (GEM) post-doc and developer of OpenSHA and the Uniform California Earthquake Rupture Forecast version 3 (UCERF3). He now develops software and tools to support updates to USGS national hazard models and related research.
