Leading specialists in various disciplines were first invited to a multidisciplinary workshop funded by ICSU on the topic to gain a better appreciation and perspective on the subject of comet/asteroid impacts as viewed by different disciplines. This volume provides a necessary link between various disciplines and comet/asteroid impacts.

In 1908 an atmospheric explosion in northern Siberia released energy equivalent to 15 Mton of TNT. Can a comparable or larger NEO affect us again? When the next NEO strikes Earth will it be large enough to destroy a city? Will the climate change significantly? Can archaeology and anthropology provide insights into the expected cultural responses with NEO interactions? Does society have a true grasp of the actual risks involved? Is the Great Depression a good model for the economic collapse that could follow a NEO catastrophe? This volume provides a necessary link between various disciplines and comet/asteroid impacts.

This text illustrates the range of environmental geoscience mapping presently carried out around the world. Specialists in several countries have contributed a number of subdisciplinary and thematic topics including volcanic hazards, landslides, dolines, tsunamis, radon potential, medical geology, rainfall erosion, engineering geology, borehole stratigraphy, lake sediment geochemistry, aggregate resources and remote sensing. The collection, analysis and interpretation of data by geologists, geographers and engineers typically involves the presentation of information in map form, which can range from black/white to colour, 2-D to 3-D and paper copy to digital format illustrations. This volume reaffirms the global need for mapping geoscientific data.
