This is the May 8, 2014 hearing, "Electromagnetic Pulse (EMP): Threat to Critical Infrastructure" before the House Committee on Homeland Security, Subcommittee on Cybersecurity, Infrastructure Protection, and Security Technologies. From the opening statement of Scott Perry: "EMP is simply a burst of electromagnetic radiation that results from certain types of high energy explosions or from a suddenly fluctuating magnetic field. A frightening point is that EMP can be generated by nuclear weapons, from naturally-occurring sources such as solar storms, or specialized non-nuclear EMP weapons. Nuclear weapon EMPs are most catastrophic when a nuclear weapon is detonated at high altitude, at approximately 30 kilometers (20 miles), above the intended target. The consequences of such an attack could be catastrophic; all electronics, power systems, and information systems could be shut down. This could then cascade into interdependent infrastructures such as water, gas, and telecommunications. While we understand this is an extreme case, we must always be prepared in case a rouge state decides to utilize this technology. Currently, the nations of Russia and China have the technology to launch an EMP attack, and we have speculated that Iran and North Korea may be developing EMP weapon technology. This is why we must remain vigilant in our efforts to mitigate the effects of an EMP attack." Statements, letters, and materials submitted from the record include those of the following: Scott Perry, Michael McCaul, Trent Franks, Peter Vincent Pry, Michael J. Frankel, and Chris Beck
