Based on information provided by the latest Japanese software, a 6 Richter earthquake in Tehran can cause 63,000 deaths. While the number was presumed to be “more than 360,000 deaths” in 1996; “however we are not still completely prepared if an earthquake occurs,” said Ahmad Sadeghi, head of Tehran Crisis Prevention and Management Organization.
The Japanese catastrophe risk modeling software platform enables clients to quantify and manage the potential impacts of natural hazards according to imported data. The models are based upon innovative applications of the latest science, engineering expertise, claims and exposure data, and advanced mathematics.
Tehran is located in a high seismic zone. The seismic study of the region shows that it is prone to moderate as well as large earthquakes. A part of Tehran’s fault line passes through the city’s north and south residential area and they are seismically active. The faults have ability to release seismic waves of 6-7 degree on the Richter scale.
Constructions
In the past the fault lines have caused several quakes, therefore, construction on faults and their surrounding areas should observe specific criteria in terms of quality of building materials, standard height and application type, Mehr news agency reported.
A high-intensity earthquake in Tehran is a reality which should be accepted. Risks and vulnerability can be minimized by considering necessary preventive measures such as; construction of quake-resistant buildings and disaster-preparedness among people and education and government institutions as well as private sector. The media have an important role in creating people’s awareness and training and striving for a safe and sustainable city in the face of natural disasters. Estimates indicate that about 10% of the people have undergone training on disaster preparedness. Media can be used to promote and publicize such education to cover a larger population.
Reducing Impact
The notion that nothing can be done against earthquakes or that an earthquake can cause complete destruction is not true. “With retrofitting of the city’s old texture and forecasting, and with the necessary preparations in place, we can reduce the consequences,” Sadeghi said.
The main fault lines active in Tehran include: Mosha-Fesham, North Tehran and south and north Rey. North Tehran fault line is the most salient tectonic factor; it begins in the slopes of Alborz Mountains and Toochal heights and extends from Kan in the west to Lashgarak in the east. Also south and north Rey faults are the most salient in the southern plain of Tehran. They have dispersed on both sides of Rey subsidence.
