Hana; at about 4:00 a.m. local time to hear the horrific explosion in Marivan, raised concerns among people in the city.
Following this incident, some news sources close to the Islamic Republic linked the sound to the earthquake, but after an investigation by the media team of the Hana Organization, it was noticed that no information had been recorded by the Iran Seismological Center.
Earlier, the International Atomic Energy Agency (IAEA) claimed in a November 2011 report that Iran had carried out large-scale explosive experiments in the Marivan region, but Iran's representatives at the International Atomic Energy Agency (IAEA) denied this claim.
