It is not possible to build in Istanbul today without meeting the requirements of earthquake resistance, as earthquake insurance in Turkey is compulsory insurance that protects construction costs after damage to the building as a result of natural disasters such as earthquakes, fires and collapses, and provides financial support to real estate owners to rebuild later, this is what it was introduced by the Turkish government after the devastating 1991 earthquake that claimed many lives and caused many material and moral losses. This insurance is extracted from the Natural Disaster Insurance Corporation known as “DASK”, which is directly supervised by the Turkish Ministry of Finance.
