INSUBCONTINENT EXCLUSIVE:
The city of Tehran is at risk of earthquakes, displacement, migration of population, and the vulnerability of buildings and bad excavations
In the social dimension, informal settlements are common concerns, especially in suburban areas
For crisis management at the national level, the country's crisis management organization (Ministry of the Interior) and at the local
level, Tehran Municipality conduct two the Tehran Crisis Management Headquarters, related to infrastructure provision and coordination; and
wastewater network that still has problems such as leakage
The wastewater network is now being developed
the terminal for domestic flights
Imam Khomeini International Airport (IKIA) is located some 30 kilometers southwest of the city
to structural engineering reports, and some are modern and safe
health facilities, the city has more than 200 hospitals and clinics that provide a variety of services, and according to the reports of the
Ministry of Health, less than 20% are safe in an earthquake with a magnitude greater than 6.5 and about 47% are relatively prepared for
severe earthquakes.Earthquake risk assessment for Tehran has been done in order to provide an insight into the relative risk situation
of earthquakes, active fault map, geology, etc.) to assess the risk of earthquakes in Tehran
environment was also analyzed using seven GIS-based vulnerability datasets (land use, urban context, building height, occupancy, structure
type, and age, as well as the proximity of some critical infrastructures) have been evaluated and as a result, the earthquake risk has been
calculated.For the main, medium, and minor faults of Tehran, the surface rupture zone around the faults should be considered a high-risk
area and prohibited for construction.Tehran is in a seismic absence and a long silence in terms of earthquake occurrences after the last
The population density map of Tehran clearly shows that out of 22 Municipality districts in Tehran, eight districts are the densest
population is precisely concentrated in the most dangerous vulnerable places, which should be considered an urgent issue in future urban
previous studies on the vulnerability of urban tissues and building loss models in Tehran
The overall risk map drawn as a result of the combination of risk, exposure, and vulnerability maps and shows an estimate of risk
However, the level of risk should not be underestimated in other districts, especially the northwestern districts (i.e
between our study and the previous study of physical-socio-economic risk assessment in Tehran shows that areas no
10, 17, 20, 16, 15, and 11 have the highest risk.The author is a professor at the International Institute of Earthquake Engineering
