A Periodical Approach to Earthquake Damages in Turkey; 3 Periods, 3 Earthquakes

44786

Rural-to-urban migration that has gained intensity as from the 1950s in our country continues at speed by the participation of millions of people. This migration trend has caused rapid, widespread, and unsupervised settlement in cities. Urban housing that significantly increased as from the second half of the 1980s created hundred of thousands of new buildings and millions of houses in the 1990s. Building quality has been pushed into the background by a large variety of reasons such as technical failures, omission, lack of control, and legal holes during the intense housing process. 3 different housing periods in terms of building safety emerged under these circumstances. Related periods are pre-1990 period, 1990-2000 period, and post-2000 period. The 1990-2000 period is a more problematic period in terms of building safety compared to other periods. Several data related to the 17 August 1999 Marmara Earthquake, 23 October 2011 Van Earthquake and 24 January 2020 Elazığ Earthquake confirm this periodical approach. For those data, there is a remarkable relationship between earthquake loss risk and construction period of buildings. Much as the efforts for transforming risky buildings by urban transformation applications have continued from 2012, related buildings are expressed as millions of houses.
