Comet and Asteroid Impact Hazards explores the anticipated
consequences of comet and asteroid impact. It presents the first
computer simulations of the hazards of comet and asteroid
bombardment of a populated Earth. Previous estimates of fatality
and damage rates on the 100 to 10,000 year time scale are shown to
be too low because they neglect rare, highly lethal outriders of
the populations of bombarding objects, those with exceptional
strength, unusually low entry velocity, and near-horizontal entry
angles. This is the first realistic assessment of both the mean
casualty rate and the expected statistical fluctuations in that
rate. A breakdown of fatality and damage rates by impactor energy
and compositional class suggests lessons for both asteroid search
strategies and interdiction techniques.
This book is written so that anyone with college level experience
in the physical sciences can understand it. It includes a disk that
allows the reader to simulate impact catastrophes. It serves as a
useful resource in various physical sciences courses such as
astronomy, planetary science, and environmental science.
* Quantatively rigorous treatment of the state of impact hazard
prediction, including stuctural blast damage, firestorm ignition,
tsunami generation
* Realistic treatment of the impact on population, composition, and
orbits
* Attention to economic and public policy issues of warning,
interdiction, and asteroid and comet search strategies
* Comparison of simulation results to historical records
* Detailed and realistic Monte Carlo simulation software
included
This work is addressed to advanced undergraduate and graduate
students in astronomy, geology, chemistry, meteorology, and the
planetary sciences as well as to researchers with pertinent areas
of specialization who desire an introduction to the literature
across the broad interdisciplinary range of this important topic.
Extensive references to the pre-spacecraft literature will be
particularly useful to readers interested in the historical
development of the field during this century.
