He told IRNA that the latest survey on the above faultlines show that they are likely to cause earthquakes exceeding 6 degrees on the open-ended Richter scale.
Turning to the faultline in northern Tehran and Mahdasht as the most active in Tehran province, he said that despite the available information, the current data and limited researches conducted so far are not sufficient to predict the time quakes are likely to occur.
"However, given the increased activity of other faultlines and the data currently available, it can be deducted that the faultlines in northern Tehran, Mahdasht and southern Karaj are active."
Zare, also a faculty member of the International Seismographic Research Center, said, "The quake which jolted Changoureh on June 22, 2002, resulted from strong jolts in a faultline which became active in 1962 and shook Boin Zahra.
