Scientists confirm Iran earthquake was natural, debunk nuclear test claims

A magnitude 4.5 earthquake struck Iran on October 5, 2024, leading to rumors that it was a nuclear test. A study from Johns Hopkins University, published on February 3, 2025, confirmed the quake was a natural event, not linked to nuclear activity. Researchers analyzed seismic data and ruled out any connection to a nuclear test, noting that such tests have distinct signatures. They highlighted the rapid spread of misinformation on social media, with claims emerging shortly after the earthquake. The study emphasized the role of accurate scientific communication in countering misinformation. It suggested that scientific agencies should quickly release reports to clarify events and reduce misleading narratives.
