Modern Geomatics Technologies and Applications

As shown in Figure 4, in case of a 7-magnitude earthquake in the North Tabriz fault, the whole city of Tabriz
will be affected by this earthquake. Due to the severity of the earthquake and the worn texture of the north and
east regions of Tabriz, most of the destruction of buildings is observed in these areas. Calculations indicate that
in case of occurrence of this earthquake, 23.7% of the city's buildings will be completely destroyed and 40.1%
will be uninhabitable and unusable, which indicates a caution for this city. The results of this analysis are similar
to the results of research [6]. The calculation of casualties using Equation 3 also showed that 454111 people
(28.5%) in the city would die and 597514 would be injured (37.5%). These injured people will need immediate
medical attention.
The simulated environment of Tabriz in AnyLogic7.0.2 software was shown in Fig. 5. In this dynamic
simulation, victims, search, rescue, medical, hospital, and central agents were presented. Injured individuals were
located in the center of the city blocks. Hospital agents located in their actual position. Besides, the distribution
of other agents was performed randomly. Due to the high volume of computations in the simulation, each agent
in the simulated environment was assumed 100 people in the real world, albeit this number is variable and can be
reduced depending on the computing power of the computer used.

In AnyLogic software, for each agent, in addition to defining features and functions, the work process (state
chart) can also be specified. The simulated workflow for each factor saw shown in Fig. 6.
