Under the Auspices of the Association of Engineering Geologists, selected authors of oral and poster presentations at the recent Joseph F. Poland Symposium on Land Subsidence will prepare written papers lot this comprehensive compendium. In this volume you will find papers that describe current and historical research, new approaches for subsidence measurement and predictive modeling, case histories describing site exploration and evaluation, damage to infrastructure, and engineering of remedial construction, and discussion of legal and political issues related to land subsidence. Contributors from the United States and many other countries are researchers, practitioners, planners, and attomeys with experience in the study, mitigation, and · societal impact of land subsidence. The career and contribution of Joe Poland will be presented as discussed by his colleagues: friends, and family at the recent symposium named in his honor.

Topics include land subsidence associated with:

• migration or removal of subsurface
• fluids: ground water, brine, hydrocarbons
• hydrocompaction of moisture deficient sediments: debris flow deposits, artificial fill
• oxidation of peat deposits
• collapse of underground and solution mine voids
• tunneling
• karst
• terrain
• tectonics
