Months before the end of World War II, an American intelligence agency launched a top-secret project aimed at devising ways to trigger massive earthquakes and tsunamis that would wreak havoc among enemy civilian populations, recently uncovered documents reveal.

According to a detailed report, project planners from the Office of Strategic Services, the nation's first intelligence agency and precursor to the CIA, concluded that the United States could use its "new atomic bomb" to trigger massive earthquakes and tsunamis, thus creating "massive destruction, death and unchecked hysteria."

[...]

As the report's subtitle, "Against Japanese Homeland," clearly indicates, the island of Japan was the selected target. Queried the report, "Scientifically can heavy bombing, pinpointed on known earthquake areas, bring about an underground condition within fault sections which would step up the expectancy and possibly bring about a calamitous earthquake in a selected area?"

Answered N. H. Heck, assistant director of the U.S. Coast Geodetic Survey, "This question has been asked several times, so it should receive a serious answer. All that could be applied is trigger force, and this can only advance and set the time for an earthquake which is about to occur. It is conceivable, however, that an explosion at exactly the right time and place might have the correct effect."

A letter cited in the report from the Seismological Laboratory of the University of California to Dr. L.H. Adams of the U.S. Geophysical Laboratory and OSS scientists reads: "… we would have to get (bomb) within less than 5 miles of that place on the fault which is destined to break within a year."
