Özet

Earthquakes are natural events that cause damage to the built environment. These damages can be classified as structural and non-structural and can vary regionally and spatially. In the immediate aftermath of an earthquake, it is crucial to obtain macroseismic intensity distributions in terms of Modified Mercalli Intensity (MMI). Given that macroseismic intensity levels can be derived from empirical relationships, an field survey-based macroseismic intensity distribution map is necessary to assess the alignment between empirical and field survey-based maps. To accomplish this, a team of experts, including geotechnical and structural engineers, investigated the areas affected by the earthquake sequence that occurred on the 6th of February in Kahramanmaraş. The damages were assessed using a region-based approach, employing contour mapping. Subsequently, a field survey-based macroseismic intensity distribution map was created, making it available for use in resilience assessments and disaster management planning.
