Iran is in a zone of tectonic compression. The Arabian plate is moving into the Eurasian plate and this is why 90 percent of the country can be affected by earthquakes. One temblor in 2003 with more than magnitude 6, killed at least 26,000 people in the city of Bam. The probability that a major earthquake can occur in Iran in the future was announced by scientists after new geological studies were released. This will reopen probably contradictory discussions with Iran’s Arab neighbors because they have big concerns about the risks of radioactive leaks related to Iran’s nuclear plant. Iran has a strong support for its nuclear program from the part of Rusia.
