Izmir Metropolitan Municipality continues its efforts to make the city a resilient city after the earthquake that occurred in Izmir on October 30, 2020. Minister Tunç SoyerStating that they started Turkey's most comprehensive earthquake research and risk reduction projects in İzmir, he said, “I believe that the studies carried out in İzmir will be a model for other cities.”
Izmir Metropolitan Municipality, which started the most comprehensive earthquake research and risk reduction projects in Turkey after the earthquake that took place in Izmir on October 30, 2020 and in which 117 people lost their lives, continues its activities without interruption. The Metropolitan Municipality, which signed a protocol with Izmir Institute of Technology, METU and Çanakkale Onsekiz Mart University for seismicity research and soil behavior modeling, and Izmir Branch of the Chamber of Civil Engineers for building inventory work, carries out a comprehensive study on both faults and soils and structures. BayraklıIdentity documents of 31 thousand 146 buildings were prepared in Istanbul. Comprehensive research on fault lines and ground, which is thought to affect the city, continues with the examination of 62 thousand buildings in Bornova.
“We will continue to do what we can”
Mayor of Izmir Metropolitan Municipality Tunç SoyerStating that such a comprehensive project was launched in İzmir for the first time in Turkey, “After the earthquake, our top priority was to make İzmir a resilient city. First of all, people of Izmir need to feel safe in the city they live in and in the buildings they live in. For this, we have implemented Turkey's most comprehensive earthquake research and risk reduction projects. We both started to work on the inventory of the existing building stock in the city and took action for seismicity research and soil behavior model. We will continue to do whatever we can to make everyone feel safe in İzmir.”
Active faults are mapped
Concrete and clear information about İzmir's seismicity will be obtained thanks to the studies initiated to examine the fault lines on the sea and land, which have the risk of affecting the city, and to model the tsunami hazard. With the study in which all active faults on the area determined within a radius of 100 kilometers in İzmir will be mapped, the future disaster-safe spatial planning and construction roadmap of İzmir will be determined.
Earthquake generation potential will be determined
Experts working on faults in an area with a radius of 100 kilometers on land took samples by digging trenches in Narlıdere, Seferihisar, Bergama, Kemalpaşa, Urla, Konak, Bornova, Menderes, Foça, Menemen, Aliağa and Turgutlu, Soma, Şehzadeler and Akhisar; Studies in this direction continue in other districts in the project area. The trench paleoseismological system, which is used all over the world, is used in land earthquake research. After the samples taken are examined, the earthquake generation potentials for these fault zones will be revealed.
Drilling at 37 points
In addition to the researches on land, samples are taken from the bottom by drilling at 37 points in the sea on the shores of İzmir. METU Marine Paleoseismology Research team continues drilling in the Gulf. Thus, not only the traces of ancient earthquakes, but also the traces of tsunamis and landslides that developed in the loose material on the seafloor can be traced.
When the drilling works are completed, it will be possible to obtain information about the earthquakes produced by the faults in the past and to make sound predictions about the earthquakes to be produced in the future.
Ground investigation continues
While the seismicity research, in which faults were examined, continued, modeling of soil structure and soil behavior characteristics was started from Bornova. Drilling wells of 50 meters were drilled in the district. In order to understand the movement of earthquake waves, measurements are made at 565 points. When the works are completed, the suitability for settlement will be evaluated by taking into account all kinds of disaster risks in the district. In project scope BayraklıMicrozonation studies are carried out in a total area of 12 thousand hectares within the borders of Bornova and Konak.
Buildings in Izmir are being examined
Within the scope of the building inventory study, Bayraklı31 thousand 146 structures were examined in . The project data were analyzed with the street scan made in the field, and it was integrated with the concrete strength data obtained from the analyzes. Within the scope of the inventory work, the building identity document system was developed, which allows the citizens to access the most comprehensive information about the buildings they live in. Thus, direct access to building permit, architectural project, assembly area and similar information was provided without making an official application to the municipality.
903 thousand 803 buildings in Izmir will be examined
building inventory BayraklıIt was started in Bornova after . Teams continue to work intensively to examine 62 thousand structures. Building inventory studies and building identity document system Bayraklı and Bornova, it will be expanded to 903 thousand 803 buildings throughout İzmir.
Established Turkey's most comprehensive building and soil laboratory
Izmir Metropolitan Municipality also established Turkey's most comprehensive building and soil laboratory in Çiğli. Egeşehir Laboratory in Çiğli is important in order to carry out the tests and analyzes needed in earthquake and soil and structure researches at international standards.
Studies are carried out by experts
