Tehran Fault Lines to Be Reexamined
Tehran Crisis Management and Prevention Center with the cooperation of two other organizations will undertake a unique proj ect to study and locate Tehran's fault lines by examining two-dimensional seismographic data, ISNA wrote.Maziar Hosseini, head of the center, said in a meeting with Tehran Municipality officials that the project was going to be implemented in the capital for the first time by top-level experts in geophysics and geotechniques.
The Oil Discoveries Company and the International Seismology Research Center will assist with the project. Similar projects have only been conducted in a few advanced countries.Hosseini noted that Tehran's fault maps have been drawn based on exterior evidence and aerial photos.
"Surprisingly, the fault lines observed in the vicinity of Tehran in the maps disappear altogether when we get to older districts of the city. How can we
justify the abrupt fading of faults that have extended over kilometers? Just because there are no proven shallow faults in those areas, does not mean that fault lines are nonexistent in deeper underground parts as well," he explained.
"As per estimates, we should dig into a minimum depth of four kilometers. For that purpose, we will use equipment supplied by the Oil Discoveries Company, working on two discrete north-south and east-west profiles."
