DHS Needs to Take Threat of EMP Attack Seriously, Physicist Warns

By Matthew Harwood

The Department of Homeland Security has not taken seriously the threat that high-altitude detonation of a nuclear weapon could fry the nation's power grid, a physicist told lawmakers yesterday.

Dr. Michael J. Frankel warned the Judiciary Subcommittee on Terrorism and Homeland Security that a terrorist organization or a rogue state could detonate a nuclear weapon either above the United States or close to its shores, creating an electromagnetic pulse attack that could severely damage the country's electronic infrastructure. Frankel is executive director of the EMP Commission, which was created in 2001 to study the national security threat an EMP attack could pose to the United States. While most of its work is classified, the commission has released two unclassified reports: one in 2004 (.pdf) and another in 2008 (.pdf).

"The EMP generated on the ground from such a high altitude detonation will not immediately damage a human being, indeed a person will not even feel it," he said. "But it will affect all of the electronic circuitry which surrounds and sustains him."

The 2008 EMP Commission report, however, expressed the threat in much stronger language. "Because of the ubiquitous dependence of U.S. society on the electrical power system, its vulnerability to an EMP attack, coupled with the EMP’s particular damage mechanisms, creates the possibility of long-term, catastrophic consequences," the report warns, noting "[s]hould significant parts of the electrical power infrastructure be lost for any substantial period of time, the Commission believes that the consequences are likely to be catastrophic, and many people may ultimately die for lack of the basic elements necessary to sustain life in dense urban and suburban communities."

The effects of an EMP event isn't theoretical, Frankel said. In 1962, the United States conducted a high-altitude nuclear test above Johnston Island, 825 miles southwest of Hawaii. Detonated 400 kilometers above the island, the resulting nuclear blast knocked out street lights across Hawaii and tripped circuit breakers, triggered burglar alarms, and damaged a telecommunications relay facility on the island of Kauai.

'One Second After' book based on 2008 EMP Report

An excellent story that details what could happen if one or more EMP devices were explosed over the US or anywhere.  A New York Times Best Seller by William Forstchen. The scary truth that our govt. and DHS are ignoring to our peril.
