In the Gebze district of Kocaeli, the heartbreaking news was delivered to 18-year-old Dilara, who lost her mother, father, and two siblings in the building that collapsed on October 29. After being rescued from the rubble, she underwent treatment in intensive care for several days, and the news was given to her with the support of psychologists.

The tense wait continues after the disaster that occurred on October 29 in the Gebze district of Kocaeli. Scientists are examining meters below the ground using "seismic reflection" and "tomography."
On October 29 in Mevlana Neighborhood, a 7-story building collapsed, resulting in the deaths of Emine (37) and Levent Bilir (44), along with their children, 12-year-old Muhammet Emir and 14-year-old Hayrunnisa Nur Bilir. 18-year-old Dilara Bilir was rescued alive from the rubble. Following the disaster, research on ground and building safety in the area continues, and three days later, cracks appeared in the columns of a 5-story building on İbrahim Ağa Street in Gaziler Neighborhood. As a precaution, a total of 21 buildings, 28 workplaces, and 79 independent units were evacuated under security measures.
DILARA BILIR DISCHARGED FROM INTENSIVE CARE, BAD NEWS RECEIVED
Today, Dilara Bilir, who was discharged from intensive care and transferred to the normal ward, was informed, with the assistance of psychologists, that she had lost four family members.
CITIZENS RETRIEVING EMERGENCY BELONGINGS WITH THE HELP OF TEAMS
Meanwhile, citizens who came to some of the evacuated buildings in Güzeller Neighborhood retrieved their emergency belongings with the help of teams and left the area. Diyar Hamitoğulları (23), who said their shops had been sealed for 4 days, stated, "We evacuated our workplace at one-hour intervals. We handed over our keys. We have suffered financially. There is an uncertain situation. This place will be closed until further notice."
GEOPHYSICAL STUDIES ARE BEING CONDUCTED
In the studies conducted by the teams of the Ministry of Environment, Urbanization and Climate Change, more than a thousand buildings are being scanned. Scientists are conducting detailed analyses using all known techniques. AFAD, along with scientists from the Ministry of Environment, Urbanization and Climate Change and universities, is carrying out comprehensive geophysical studies to determine the cause of the collapse and assess the safety of surrounding buildings.
METERS BELOW THE GROUND ARE BEING IMAGED
Expert teams are examining meters below the ground in the area where the building collapsed using the "seismic reflection" method. Seismic waves created by a special weight drop system are measured to identify layer differences, water accumulations, and weak soil areas in the ground. Additionally, with the "Electrical Resistivity Tomography (ERT)" system, cables are laid at regular intervals to send electric current into the ground. This method allows for the imaging of the ground's structure, layer differences, and potential voids in detail. A ground map of the region will be created with the obtained data.
BUILDINGS ARE BEING MONITORED WITH MEASUREMENTS
Not only the ground but also the surrounding buildings are being monitored with advanced technology devices. Thanks to georadar scanning devices placed in the buildings, potential movements and structural deviations are being observed. The system, which operates at a 135-degree angle, scans all buildings and detects even the slightest movements, reporting them.
Additionally, geodetic measurement devices are recording deformation, deviation, and mobility in the area. This way, it is determined whether the buildings are moving, whether there is a static problem, and how changes in the ground affect the structures.
427 PERSONNEL ARE WORKING
A total of 427 personnel and 120 vehicles from 27 public institutions and organizations are working in the field. Additionally, the General Directorate of State Hydraulic Works and the General Directorate of Mineral Research and Exploration are examining maps. Thus, many parameters and technical data are being compiled to prepare a healthy report.
IS THERE A WATER WELL UNDER THE BUILDING?
Moreover, drilling work is being conducted by experts from universities to determine whether there is a water well in the ground of the Arslan Apartment, which has been cleared of rubble. The teams from the General Directorate of Construction Affairs of the Ministry of Environment, Urbanization and Climate Change are also measuring the mobility in the buildings with the georadar device that scans at a 135-degree angle during this work.
It has been reported that millimeter data is being collected through sensors placed in the buildings and risks are being reported.
