This document discusses the pattern of disaster tech innovation, where emerging technologies are adapted in response to disasters and then iteratively improved. It provides examples like Google Maps and Twitter being used ad-hoc during Hurricane Katrina, the development of OpenStreetMap in response, and InSTEDD using SMS for coordination during wildfires. It also discusses how existing models could have helped with the 225,000 deaths from the 2004 Boxing Day tsunami if the technologies had been connected. The document advocates being prepared to champion technologies when disasters occur and continuing to iteratively improve them.
