Perspective: EMPThe Threat of an Electromagnetic Attack

Published 29 July 2019

When much of Venezuela was plunged into darkness after a massive blackout this week, President Nicolás Maduro blamed the power outage on an “electromagnetic attack” carried out by the U.S. The claim was met with skepticism, but Maduro’s claim has raised questions over what exactly is an electromagnetic attack, how likely is it to occur and what impact could it have.

When much of Venezuela was plunged into darkness after a massive blackout this week, President Nicolás Maduro blamed the power outage on an “electromagnetic attack” carried out by the U.S.

The claim was met with skepticism. Blackouts are a regrettably frequent part of life in Venezuela, where the electric grid has fallen into serious disrepair.

Nevertheless, AP writes, Maduro’s claim has raised questions over what exactly is an electromagnetic attack, how likely is it to occur and what impact could it have.

In the 1962, during the Cold War, the U.S. detonated a nuclear weapon above the atmosphere over the Pacific Ocean, and the experiment — known as Starfish Prime — knocked out power to traffic lights and telecommunications in parts of Honolulu, illuminating the sky and even leading hotels to host viewing parties, according to news reports.

Russia conducted a series of “high-altitude nuclear bursts” in 1961 and 1962 to test electromagnetic pulse impacts over Kazakhstan and destroyed that country’s electrical grid, according to testimony to Congress from the Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack.
