Extreme events engineering is an experience-driven field. Immediately following the occurrence of an extreme event (e.g., earthquake, tsunami, hurricane, landslide, or flood), perishable data that can be used to advance our understanding should be systemically collected. The importance of detailed mapping and surveying of damaged areas relative to general damage surveys cannot be overemphasized, as they provide the hard data of the well-documented case histories that drive the development of many of the empirical procedures used in geoengineering practice. The GEER Association is working to develop a systematic approach to conducting the NSF-sponsored reconnaissance efforts of the the geotechnical effects of extreme events. The project is formalizing the manner in which extreme events reconnaissance efforts are organized by the GeoPrograms of NSF.
