Claims of manmade quake spread online after southwestern Japan disaster
Following a magnitude 7.1 earthquake in southwestern Japan, claims that the disaster was manmade rapidly spread online, despite experts dismissing such theories as technologically and financially unrealistic.

Social media platforms saw a surge in posts suggesting the Kumamoto earthquake was an 'artificial earthquake,' with one viral post garnering millions of views. Experts from the Seismological Society of Japan have refuted these claims, citing the immense practical and technological challenges of creating such a deep and powerful tremor, while also noting that social media's reward stru…
Imagine a giant underground rumble, like when a big truck drives by, but way bigger. Some people online are saying that someone secretly caused this big rumble, like a hidden giant pushing the ground. But scientists, who study how the Earth works, say that's like trying to dig a hole to the center of the Earth with a tiny shovel – it's just too hard and takes too much power for anyone to do on purpose.

The Digital Echo Chamber of Misinformation
Following the magnitude 7.1 earthquake in Kumamoto Prefecture, southwestern Japan, social media platforms, particularly X (formerly Twitter), became fertile ground for the rapid dissemination of claims suggesting the tremor was manmade. One post, asserting the seismic wave was from an explosion rather than a natural quake, garnered approximately 3 million views. Analysis tools revealed a dramatic increase in mentions of 'artificial earthquake' in Japanese posts, surging from hundreds before the disaster to tens of thousands in the days immediately following. This phenomenon underscores how quickly unverified and misleading information can spread in the digital age, especially during moments of high anxiety and uncertainty.
Scientific Rebuttal to Unrealistic Claims
Experts, including the Seismological Society of Japan, have unequivocally dismissed the notion of a manmade earthquake of this scale as 'unrealistic.' The Kumamoto earthquake struck at a depth of 16 kilometers. Scientists explain that drilling a hole 10 kilometers or deeper would be an incredibly time-consuming and costly endeavor, fraught with immense practical difficulties in generating the necessary energy to trigger such a powerful temblor. While nuclear tests have caused major tremors, the technology required to conduct a nuclear explosion at such a depth remains unestablished. The deepest hole ever dug, the Kola Superdeep Borehole, took two decades to reach 12.3 kilometers, illustrating the monumental challenge involved.
Psychology and Platform Dynamics Fueling Falsehoods
The persistence of these manmade earthquake claims, despite scientific refutation, can be attributed to a combination of psychological factors and social media platform dynamics. Reo Kimura, a professor of disaster psychology, notes that during anxiety-inducing situations, individuals often gravitate towards simple narratives, such as an event being intentionally caused, as these are more readily accepted than complex scientific explanations. Furthermore, the Japan Fact-check Center points out that social media's reward structures, which allow users to earn revenue from engagement, incentivize the creation and sharing of sensational, even if false, content. This creates a feedback loop where misinformation can thrive, driven by both belief and financial motivation.
Key points
- Claims of a manmade magnitude 7.1 earthquake in southwestern Japan spread widely online.
- One viral post on X suggesting an 'explosion' caused the quake received around 3 million views.
- The Seismological Society of Japan dismissed these claims as 'unrealistic' due to technological and financial impossibilities.
- Experts cite the immense difficulty and cost of drilling to the earthquake's depth and generating such energy.
- Social media's reward structures and human psychology contribute to the rapid spread of misinformation during anxious times.
The widespread discussion of these claims, even if false, could lead to increased public awareness regarding the importance of fact-checking and critical thinking when consuming information online, especially during crises. It might also prompt social media platforms to enhance their efforts in combating misinformation.
The continued spread of unsubstantiated claims during a natural disaster can erode public trust in official information sources and scientific experts, potentially hindering effective disaster response and recovery efforts. It also highlights the vulnerability of societies to manipulation through online narratives, making it harder for people to discern truth from falsehood.
