THE GEOLOGICAL RECORD OF IMPACTS ON THE EARTH AT ROYAL

Last Updated on Friday, 07 May 2010 19:42

This one-day discussion meeting in the Royal Astronomical Society's regular monthly programme will review and challenge current understanding of cratering and impacts throughout the history of the Earth, setting a context for possible disaster scenarios in the future, which might involve comets, meteorites, or asteroids. There will be contributions on some of the best direct geological evidence for impacts, discussions of global threats, frequency of impacts, known and potential extinction events, and the devastating secondary consequences of impacts, which may include earthquakes, tsunamis, landslides, and volcano activity. The keynote talk is by Christian Koeberl (Vienna), President of the IMPACT programme of the European Science Foundation (web site http://www.esf.org/).


Media representatives are welcome to attend. The meeting is in the Geological Society Lecture Theatre at Burlington House, Piccadilly, London, W1.
