The 7th IASPEI / IAEE International Symposium on the Effects of Surface Geology on Seismic Motion (ESG7)

The 7th IASPEI / IAEE International Symposium on the Effects of Surface Geology on Seismic Motion (ESG7) will be held on October 19–21, 2026, in Grenoble, France.

ESG7 will explore all facets of site effects on ground motions, including the challenges of quantitatively predicting ground motions that incorporate these effects. Continuing the tradition of ’blind test experiments’ organized by the JWG-ESG community during past ESG International Symposiums, which provided benchmarks for seismic motion prediction and site characterization, ESG7 proposes a blind prediction exercise focused on topographic effects and a benchmark for H/V inversion in site characterization, results to be presented as special sessions.

ESG7 also plans to hold special sessions focused on new data/methods for evaluating and characterizing site effects (e.g., Distributed Acoustic Sensing (DAS); Artificial Intelligence), last damaging significant earthquakes, and progress of studies related to ESG over the past three decades.
