This PowerPoint show depicts the effects (blast, heat, etc.) of the Chesapeake Bay impact.
To emphasize the human consequences of asteroid and comet impacts, the slides show what would happen to East Coast communities if an identical object hit the same place today. (The impact actually happened roughly 35 million years ago.)
Impact effects were estimated with the Earth Impact Effects Program (www.lpl.arizona.edu/impacteffects/). Effects shown on these slides are at best very approximate, and, consequently, these slides should only be used to stimulate discussions about impact hazards.
Satellite images were obtained through the NASA Earth Observing System Higher Education Alliance (GeoBrain) which provided funding for this work.
Graphics were created with the Environmental Systems Research Institute (ESRI) family of geographic information system (GIS) products.
