On the evening of June 20, a 5.5 magnitude earthquake occurred near the city of Sorkh in Iran's Semnan province. The earthquake was felt in places such as Tehran, Qom, Damavand, and Karaj in Iran. As a result of this earthquake, an earthquake was felt in Qom, where Iran's most notable Fordo nuclear facility is located. Iraqi seismology professor Ali Ramtan believes that scientific evidence shows that the earthquake was a natural cause and had nothing to do with the so-called nuclear tests. Ramtan explained that the first earthquake occurred in the Alborz Mountains. The magnitude of the earthquake was over 5, and the depth of the epicenter was about 10 kilometers. This is consistent with historical seismic activity in the region. He said, “This is a typical 'reverse fault earthquake'. It is impossible to carry out any nuclear tests at this depth of the epicenter.” Ramtan emphasized that earthquakes caused by nuclear tests are usually shallower in magnitude and rarely exceed magnitude 3. He also added that judging from the earthquake's seismic waveform, this earthquake was also a natural occurrence, not man-made.
