Advancing hazard-resistant design demands an understanding of what happens when a disaster occurs. Documenting and sharing the key lessons learned from extreme events around the world contributes significantly to advancing research and practice in hazards engineering. The detailed mapping and surveying of damaged areas provides the data for well-documented case histories that drive the development of many of the design procedures used by geotechnical engineers.

Many design methods are based on insights gleaned from observations from past events. Field observations are particularly important in the discipline of geotechnical engineering, because it is difficult to replicate in the laboratory soil deposits built by nature over thousands of years. Much of the data generated by an extreme event is perishable and therefore must be collected within a few days of the occurrence of the event. Thus, engineers should be ready to investigate the next important extreme event.
