The head of the Alborz Province Risk Risk Research Center stated that Iran is ranked fourth among the world’s first five countries in terms of natural disasters, and said the province’s seismic status was 5 kilometers and so far these urban areas have been identified on active faults. The earthquake return in Alborz is every 5 years, but has passed since the last major earthquake in Alborz.
According to RCO News Agency, Dr. Reza Jamalpour today, at a special meeting of the International Institute of Seismology and Earthquake Engineering, entitled “Earthquake Risk Investigating in Karaj City due to recent earthquake events in Alborz province”, said natural disasters to be out of human will, and said: Therefore, we live in a country where the natural risks are among the two countries with a high number of natural disasters, and Iran ranks fourth among the world’s top 5 countries.
He cited earthquakes, landslides, subsidence, floods, avalanches, tornadoes, thunderstorms, volcanoes, lava flows and droughts, including natural disasters, and said: Al -Bazar province, with an area of 2 square kilometers, and by removing 2 % of Iran. The statistics have a population of 1.5 million, equivalent to 4.9 percent of the country’s population.
Jamalpour noted: Alborz province has always been threatened with all kinds of natural hazards and records show that there have been a lot of damage at different times and there is currently about 4 dangers in the province and therefore al -Bazar province is threatened.
The head of the Alborz Province Disaster Risk Reduction Research Center pointed out the status of faults in the province: The total length of the faults in the province is 2 kilometers and so far these urban areas have been identified on active faults. The earthquake return in Alborz is every 5 years, but has passed since the last major earthquake in Alborz.
He described the landslides as one of the risks of the province in Alborz province and in the north of Karaj and the mountainous part of the province, especially the Chalus, Barghan and Taleghan roads.
Jamalpour cited Bahman and Flood as other risks in the province and said: Karaj-Chalus, Taleghan and Barghan mountainous axes are among the most important districts of Bahman in the province. The fall of avalanches in the cold seasons of the year disrupts the passage of these axes, and sometimes these axes are at risk of rock falling.
He pointed to the existence of subsidence in the province and noted that the limited part of the subsidence in Alborz province was about 2 square kilometers and the highest annual subsidence rate is 2 cm per year for the south of the Karaj-Qazvin highway.
Jamalpour described the subsidence as an irreversible phenomenon and said: This phenomenon is intensified in Iran from about 5 to 5 years ago and has affected all the plains and urban areas, including Tehran, with an annual event of about 5 cm in southwestern Tehran a world record, which is due to the existence of 7,000 unauthorized wells.
Head of Alborz Province Disaster Risk Reduction Research Center Land subsidence in the southwest plain of TehranEmphasized: About 2 kilometers of Azadegan Belt length, about 2 kilometers of Qom highway, about 2 kilometers from Saveh and Behesht Zahra highway, have a subsidence potential. The Tehran-South and Tehran-Tabriz railway in the southern branches of the subway to Islamshahr and the holy shrine of Imam Khomeini, as well as parts of the subway lines in the center of the city, as well as part of the Mehrabad Airport, are in this risky area.
According to him, new studies show that since the subsidence of the West Plain of Tehran has been steadily moving east and crossing agricultural land and besieging Tehran’s urban areas. Another new subsidence area is to Tehran International Airport.
