Land Subsidence Symposium, Thursday September 17, 2026

The AEG Subsidence Working Group convenes AEG’s eighth Symposium on Land Subsidence as part of the 69th annual meeting of AEG.  The symposium will begin with a summary of global land subsidence as reported in the online media during 2025-2026. Abstracts are solicited now for symposium sessions addressing land subsidence due to collapse of underground voids (mines, karst, tunnels), fluid extraction (groundwater, hydrocarbons, brine, geothermal fluids), thawing permafrost, drainage of organic soils, hydrocompaction, natural compaction, tectonics, volcanics, and relaxation from uplift in areas formerly adjacent to continental ice sheets.  Abstracts related to geophysical characterization of subsiding areas, and subsidence processes, monitoring, infrastructure damage, modeling, remediation, and regulation are encouraged as well as presentations dealing with deltas and coastal plains experiencing the multiple effects of subsidence and sea-level rise. Please contact convener, Jim Borchers, with your planned abstract topic and title, jborcher@outlook.com

Identification, Characterization, and Evaluation of Geologic and Seismic Hazards Symposium , Thursday September 17, 2026

The Geologic and Seismic Hazards Technical Working Group (GASH TWG) will convene a Symposium during which case histories addressing identification, characterization, and evaluation of geologic and seismic hazards will be presented. The innovative use of Geographic Information Systems (GIS) and remote sensing tools for data collection and analysis are of particular interest related to their application in hazard investigations and presentation of geospatial data to stakeholders. Specific hazards of potential concern depend on geologic and geotechnical characteristics of the site being studied and may include, but are not limited to, faulting, landslides, karst and subsidence in limestone terrains, and poor-quality foundation materials related to adverse site conditions. The presentations should address what data were used to identify, characterize, and evaluate the hazards and formulate plans for hazard mitigation, if applicable. Because results of the hazard evaluations and information related to mitigation planning often need to be communicated to stakeholders who are not geoscientists, the speakers could also address the approaches applied to explain the results and the recommended mitigation measures to members of the public, industry representatives, federal and state government agencies and their representatives, county and city representatives, and Native American tribal representatives. The symposium will be complemented by a student poster session that provides an opportunity for students to present the results of their research related to identification, characterization, and evaluation of geologic and seismic hazards. Please contact convener, Gerry Stirewalt, with your planned abstract topic and title, Gerry.Stirewalt@nrc.gov

Poster Session Call for Abstracts

SEEKING ABSTRACTS FOR A GASH TWG STUDENT POSTER SESSION ON “IDENTIFICATION, CHARACTERIZATION, AND EVALUATION OF GEOLOGIC AND SEISMIC HAZARDS"

 

The Geologic and Seismic Hazards Technical Working Group (GASH TWG) seeks abstracts for a student poster session to be held on Wednesday, September 16, 2026. The poster session, which will complement a Symposium of the same title that will be convened by the GASH TWG at the Annual Meeting, will showcase student research related to identification, characterization, and evaluation of geologic and seismic hazards. Posters that discuss the innovative use of Geographic Information Systems (GIS) and remote sensing tools for data collection and analysis will be of particular interest regarding their application in hazard investigations and presentation of geospatial data to stakeholders. Specific hazards of potential concern depend on geologic and geotechnical characteristics of the site being studied and may include, but are not limited to, faulting, landslides, karst and subsidence in limestone terrains, and poor-quality foundation materials related to adverse site conditions. The posters should address what data were used to identify, characterize, and evaluate the hazards and formulate plans for hazard mitigation, if applicable. Because results of the hazard evaluations and information related to mitigation planning often need to be communicated to stakeholders who are not geoscientists, the posters could also address the approaches applied to explain the results and the recommended mitigation measures to members of the public, industry representatives, federal and state government agencies and their representatives, county and city representatives, and Native American tribal representatives.
