Tehran's EarthQuake - On Behalf of Ehsan

The city of Tehran, with its vulnerability to earthquakes, has been planning a master disaster programme considering different aspects. It is hoped that, by activating all objectives. The city will achieve a better earthquake disaster management policy. A detail study based on available data only, was done to determine the seismic vulnerability of the mega-city of Tehran with a population of about 10 million people. About 640,000 residences out of 1,100,000 seem to suffer collapse or serious damage while 1,450,000 people are killed with about 4,330,000 suffering injuries. A total of 14 parameters were considered for each sub-division. Relative rating for each of the parameters considered was investigated and summarized in a table. This matrix of vulnerability indexes identified in more detail the severity of the problems for given sub-divisions. Total and then relative vulnerability for management priority attention was also considered. This indicates that relatively speaking from the worst to the least vulnerable divisions in city of Tehran are as follows: 20, 19, 16, 15, 17, 7, 8, 10, 6, 18, 14, 11, 12, 3, 2, 4, 5, 9, 13, 1. Of course this is the overall vulnerability.
Disaster management is a complex form of management which requires many disciplines and specialities. It requires a detailed allocation of tasks and a good knowledge of the domain of the disaster itself. In Iran, through many years of first-hand experience with disasters, a good knowledge of events and what to expect is well known. Also, a system has been established for handling situations. It works well but it is believed that it needs adjustment and modification. The number of earthquake disasters has increased due to the urbanization of the country, especially in earthquake-prone areas. Therefore, serious consideration of the management of these disasters is needed now more than ever. As stated, a more systematic and general approach to this phenomenon is proposed in this paper. The most important factor is that this plan considers all aspects of an earthquake disaster. It includes the problems and solutions to the general disaster cycle with little duplication of duties and tasks allocated to the respective responsible national bodies. Tehran should be redesigned and reconstructed in order to earthquake management. Most importanat and vital information should not only be at Tehran. Tehran citizens should learn how to face the earthquake.
