Konvitz, The Urban Millennium: The City-Building Process from the Early Middle Ages to the Present (Carbondale and Edwardsville: Southern Illinois University Press, 1985); and Richard T.

2. At Oregon State’s tsunami lab: Officially called the O. H. Hinsdale Wave Research Laboratory, the facility makes its data publicly available so that other researchers can build simulations based on what other scientists have learned about wave behaviors. A good example of how this data-sharing works can be found in this paper: T. E. Baldock, D. Cox, T. Maddux, J. Killian, and L. Fayler, “Kinematics of Breaking Tsunami Wavefronts: A Data Set from Large Scale Laboratory Experiments,” Coastal Engineering 56 (May–June 2009).

CHAPTER SEVENTEEN: CITIES THAT HIDE
1. frying the ozone layer off: I’m getting my account of the effects of a gamma-ray burst from astronomer Phil Plait’s excellent chapter on the subject in Death from the Skies! These Are the Ways the World Will End… (New York: Viking, 2008).
2. NORAD (North American Aerospace Defense Command) complex beneath Colorado’s Cheyenne Mountain: These days, NORAD has been relocated to another facility and the underground city is run by a skeleton crew. Nuclear weapons technology has advanced enough that the city would likely not survive a direct attack.
3. raids from neighboring groups and from Muslims during the Crusades: See a historical account of the region in Spiro Kostof, Caves of God: The Monastic Environment of Byzantine Cappadocia (Cambridge, MA: MIT Press, 1972).
4. a layer of concrete can provide more safety still: For an interesting discussion of the history of designs for radiation shielding, including contemporary thinking on the topic, see J. Kenneth Shultis and Richard E. Faw, “Radiation Shielding Technology,” Health Physics 88 (June 2005): 587–612. They point out that concrete is such a good material for most kinds of radiation shielding that it is one of the most widely studied substances for this purpose.

Not much has changed since Robock published this article in terms of our understanding of how nuclear winter would work. Many climate scientists agree that a massive explosion would plunge the planet into unseasonable winter for at least a year. Interestingly, it’s likely a megavolcano would cause the same problems we face in a nuclear disaster—minus the radiation danger. See Alan Robock, “New START, Eyjafjallajökull, and Nuclear Winter,” Eos 91 (2010).
