The earthquake that struck Iran in October 2024 sparked widespread rumors on social media, suggesting it was a covert nuclear test. However, a recent study by researchers from Johns Hopkins University, published in the journal Seismica on February 3, has conclusively determined that the event was a natural seismic occurrence. The research underscores the significant risk posed by weaponized scientific misinformation during periods of geopolitical tension. This article explores the findings and implications of this study.

Clarifying the Seismic Event: A Natural Phenomenon

Researchers analyzed the seismic data from the earthquake that occurred near Semnan, Iran, using publicly available information from monitoring stations. They concluded that the tremor resulted from a reverse fault motion caused by the collision of the Arabian and Eurasian tectonic plates. This type of geological activity is common in the region due to its location at the convergence of these two major plates. The team ruled out any connection between the earthquake and a nuclear test, emphasizing that such tests produce distinct explosive signatures not observed in this case.

The Comprehensive Test Ban Treaty Organization (CTBTO) also confirmed that similar seismic events had been recorded in the area in previous years, further supporting the natural origin of the quake. The magnitude of the event was reported as 4.5 by some sources and 4.2 by others, reflecting slight variations in measurement but consistently indicating a moderate seismic event rather than an artificial explosion. The detailed analysis provided by the researchers helps clarify the true nature of the incident, dispelling unfounded claims.

Addressing the Spread of Misinformation: A Global Concern

Within minutes of the earthquake, social media platforms were flooded with misleading posts suggesting that the event was either an Israeli strike or a covert nuclear test by Iran. These claims quickly gained traction, fueled by speculative reports from various news outlets around the world. The rapid spread of misinformation highlighted the vulnerability of public perception to unverified claims during times of uncertainty. The study points out that while some of this misinformation may have originated from simple misunderstandings, certain patterns suggest intentional efforts to mislead.

The researchers noted that mainstream English-language media often amplified these unfounded theories without seeking expert verification, inadvertently contributing to the propagation of misinformation. In contrast, Persian-language media generally reported more accurately, relying on local seismological expertise. To combat this issue, the study recommends swift issuance of detailed scientific reports and greater collaboration between social media platforms and verified experts. By prioritizing accurate, timely information, the scientific community can help mitigate the harmful effects of misinformation in critical situations, ensuring that the public receives reliable data during seismic events.
