Design and Development of Location System Based on Earthquake Damage Estimation in Tehran in ArcGIS
Abstract
The speed of relief in the early hours after a major earthquake plays a huge role in reducing earthquake casualties in an urban area. In this study, the design and implementation of a seismic damage estimation system in GIS environment was proposed as a proposed solution to accelerate relief. The design documentation for the system, including two earthquake risk and damage assessment modules, was presented as a tool in the ArcGIS environment, and the implementation was performed using the Python programming language in this environment. The risk module estimates the maximum acceleration and intensity in a network of earthquake points with experimental models. With the resulting map, cities can be prioritized on a small scale in terms of earthquake risk. The damage module calculates the amount of damage to the structure by entering the properties of the structure and using the vulnerability function. The system was implemented for four possible scenarios for the metropolitan area of Tehran and the results showed that with a platform with typical hardware specifications in less than an hour, the damaged areas in this metropolitan area can be identified. These maps will be very effective in two phases of pre-earthquake mitigation and post-earthquake relief.
