“…Izmir has a history of enduring numerous earthquakes within its provincial boundaries and in neighboring areas like Manisa, Aydın, Balıkesir, Izmir Bay, and the surrounding islands such as Samos, Lesvos, and Chios [45]. Historical earthquake records indicate multiple instances centered in Manisa, Selçuk-Efes, Foça, Turgutlu, Menemen, and Çeşme, estimated to fall within the VIII-X intensity range on the Modified Mercalli Scale [46]. These seismic events are directly linked to the active tectonic activity within the West Anatolian Extensional Province [47,48].…”

On 6 February 2023, near Kahramanmaraş in south-central Türkiye, an event underscored the vulnerability of cities to seismic activity, revealing a lack of preparedness for substantial shocks. The contributing factors are manifold, yet fundamentally, the collapse of buildings and infrastructure can be attributed to an underestimated capacity for meticulous settlement planning (location) and the adoption of advanced techniques for resilient construction (structure). Regrettably, as has been investigated by many research works, ordinary urban planning in Türkiye hardly finds ways to integrate the vulnerability analysis for settlement expansion, which includes the full integration of geological characteristics with the analysis of building sensitivity. With this work, we wanted to build a composite risk index based on earthquake vulnerability, hazard amplification map, and exposure. We designed the composite index in Izmir’s basin, Türkiye’s third most populated city, to answer the question: What if a destructive earthquake strikes this densely settled area? The results illustrates how the coupled integration of digital data on geology with settlements and infrastructure in a Geographic Information System environment can be used to produce risk maps and plan the anthropic system’s adaptation carefully. Findings demonstrate the city is highly vulnerable to earthquakes and identify priority areas for planning intervention, relocation, and renovation of buildings.

“…˙Izmir, the largest city in Western Anatolia in terms of population (4,425,789 in 2021) [60], has been affected by earthquakes in its history and has witnessed a loss of life and property. When the historical and instrumental period records are examined [61][62][63][64][65], in addition to the earthquakes that took place within the provincial borders of ˙Izmir, many earthquakes in the surrounding provinces, basins, and even the Aegean Sea caused damage to the city. As can be seen especially in the 2020 Samos earthquake, damages occurred as a result of liquefaction in the alluvial soils in the structures in the city center, and in some districts, the earthquake intensity affected the buildings more strongly for a longer period of time with the amplification effect in the earthquake waves due to the basin structure and groundwater levels.…”

It is well acknowledged that sustainable soil management can play a crucial role in reducing the vulnerability of urban areas, but are soil characteristics properly evaluated in the decision-making process concerning urbanization? Within this work, we conducted an analysis of the land-use change trends in the city of Izmir (Turkey). We made an extended and detailed analysis of the urbanization processes between 2012 and 2018 in a geographic information system environment (Esri ArcGIS 10.8.1 and ArcGIS Pro 3.0). Then, we superimposed by spatial overlay different soil characteristics: land capability, hydraulic conductibility, soil groups, and fault lines. We discovered that although there is a joint agreement on soil and its geological importance in reducing urban vulnerabilities to flooding, urban heat islands, agricultural production, or earthquakes, there is scarce knowledge of its characteristics to inform land-use planning. This work sheds some light on how newly developed areas are planned without proper consideration of soil properties, following a fuzzy and irrational logic in their distribution. Results encourage the utilization and inclusion of soil knowledge to support the decision-making process concerning urban transformation to achieve more resilient and less vulnerable urban systems.

Along the mountain front, the Manisa Fault Zone separates the Pleistocene-Early Holocene Emlakdere and Turgutlu formations from the footwall rocks of Bornova Flysch Zone of Late Cretaceous-Paleocene age and Neogene volcano-sedimentary units (Okay et al., 1996, (Figure 2). E-W to NW-SE-striking Manisa Fault Zone (MFZ) is made up of two main fault segments at a total of 45 km long (Emre et al., 2018). Even though previous studies are mostly concentrated on the western segment of MFZ to explain Quaternary-Holocene characteristics (Özkaymak et al., 2011;Akçar et al., 2012), the studies regarding active tectonics and paleoseismology of the eastern segment of MFZ aim to unravel the Quaternary activity, and landscape evolution has so far been rarely addressed. According to Özkaymak et al's. ( 2011) studies, the western segment is responsible for three paleo-earthquakes, which
