What did the declassified documents reveal?

Psychological Warfare Earthquake Plan against the Japanese Homeland, Office of Strategic Services, declassified document, dated during the final year of the Second World War. This memorandum outlines a proposed psychological‑warfare campaign that would link strategic bombing with the manipulation of seismic activity, and it was released through The Black Vault archive. The document was made public by The Black Vault as part of a broader declassification effort.

The memorandum opens with a prefatory analysis: “Japan is a country of social tensions.

The memorandum notes: “Today, with contemporary Japan subject to the will of the political police, the tight social regimentation of the neighborhood groups, the grinding economic exploitation, the student propaganda of chauvinism, and the Shinto superstition, are placing heavier burdens on the Japanese people than they experienced even under the stern rule of the feudal Bakufu.” The document argues that as the Japanese military and political machine “begins to crack under the hammer blows of its enemies,” violent outbursts of mass hysteria may flare up. It then proposes a psychological‑warfare campaign designed to “tighten the frustration ring around the Japanese people” and to “tie up the destruction of physical war with that of the forces of nature.” A central question posed in the memorandum is whether a large explosive charge could be used to trigger an earthquake.
