Claims that directed energy weapons (DEWs) have been used to trigger volcanic eruptions, such as at Sakurajima in Japan, are false.

The beams observed are from lidar systems used by Kyoto University for monitoring volcanic ash clouds, not weapons.

Similarly, videos circulating online showing a beam allegedly triggering an eruption are misidentified footage of scientific instruments or natural phenomena like meteorites, not DEWs.

There is no credible evidence that any directed energy weapon has been used to influence volcanic activity. While the concept of a "tectonic weapon" — a hypothetical device capable of inducing earthquakes or volcanic eruptions by manipulating tectonic stress — has been discussed in theoretical and fictional contexts

, no such weapon is known to exist or have been deployed.

The energy required to trigger a volcanic eruption through such means would be immense and far beyond current technological capabilities.

In contrast, real volcanic eruptions are driven by natural geological processes, such as the buildup and release of pressure from magma beneath the Earth's surface.

The dynamics of volcanic ballistic projectiles (VBPs), which are solid rock fragments ejected during eruptions, are well-studied and explained by physics and geology, not external energy sources.

Any suggestion that DEWs are responsible for volcanic activity is not supported by scientific evidence and is considered a conspiracy theory.
