For Turkey, where 96 percent of its lands are located within the earthquake region, the earthquake ranks first in the largest natural disaster order. In the districts of Istanbul, which bear the risk of earthquakes in the first degree, there is no compulsory earthquake insurance in the majority of the buildings.
The most recent earthquake disaster in recent history is the earthquake that occurred in the Marmara region in 1999, showing that the probability of experiencing a earthquake on the scale of scientific studies 7 and above is close. Against such high risk, the reality is that the measures against depression, building consolidation and insurance have not yet been taken into account. Although it is compulsory, the fact that the insurance rate for earthquake insurance is around 44 percent for the country is proving this fact numerically.
Generali Sigorta, who has set out from the anticipated earthquake risk in the near future, obtained Istanbul’s district-based Compulsory Earthquake Insurance map after the earthquake week (1 – 7 March 2017). The results of the work done are mixed when scientists surveying Marmara Sea are evaluated together with earthquake findings.
According to the estimates of the scientists, it is expected that 125,137 of the 5,342,014 houses in Istanbul will have heavy damages, 169,473 moderate damages and 206,187 minor damages in the Marmara earthquake that will take place in 7-8 scale. These numbers are estimated to be between 50,000 and 150,000 deaths, and the number of people exposed will be around 1,250,000.
It is predicted that 233,976 of 1.239.072 houses will see damages in the first degree earthquake areas such as Avcılar, Adalar, Kartal, Tuzla, Kadıköy, Zeytinburnu, Küçükçekmece, Pendik where the average insurances ratio is around 37.84%.
