"Powering Through" (Version 1.0) contains, for the first time, a comparison of critical infrastructures that can be adversely impacted by five high impact threats: high altitude Electromagnetic Pulse (HEMP); solar geomagnetic storms; cyber-attacks; physical attacks; and Radio Frequency (RF) weapons. The "stoplight chart" in the Executive Summary is printed on the inside cover of the book in color. This book is an Action Guide, providing an overview of infrastructure interdependencies and opportunities to protect, mitigate and recover. It addresses all five hazards to critical infrastructure, and potential cascading effects on water, wastewater and other critical infrastructures if power blackouts are long-lasting. Importantly, the book concentrates on consequence management, starting at the individual, household, and community levels of preparedness. If we are better prepared at home, we can better assist the organizations that will lead recovery, whatever the challenges.Version 1.0 is published by the InfraGard Electromagnetic Pulse Special Interest Group in December 2016 in support of a Workshop to begin outreach and improvements for a future Version 2.0. The goals for Version 2.0 are to investigate alternative resilient strategies, to model resilient island communities, and to examine the government and private sector domains and technologies to strengthen critical infrastructures and recovery opportunities in event of catastrophic losses. InfraGard is an association of about 43,000 persons who represent businesses, academic institutions, state and local law enforcements, infrastructure experts and others dedicated to sharing information and intelligence to prevent hostile acts against the U.S. It is a public/ private partnership with the FBI. The Electromagnetic Pulse Special Interest Group (EMP SIG(tm)) mission is to inform communities how to mitigate high-impact threats of long-term power and communications failure (greater than 30 days) which could lead to catastrophic, cascading losses of life-sustaining infrastructures and resources for recovery. Ordering information for hardcopy and e-book versions of Powering Through can be obtained online via www.empcenter.org, or via www.amazon.com. Net proceeds from book sales are assigned to the InfraGard Electromagnetic Pulse Special Interest Group to enable improvements to the Action Guide in a planned Version 2.0.
