1 PREVIOUS AND ONGOING STUDIES ON THE GEOLOGY AND ACTIVE FAULTS OF THE IZMIR REGION By MTA Ömer Emre General Directorate of Mineral Research and Exploration (MTA)

2 MTA DATA BASE A-Collected data in the last 10 years Geological maps *Digitized basic geological maps in scale of 1:25 000; 1:100 000; except for L18 sheet (available in Geological Data Base) * Quaternary geological and geomorphological maps of the Gediz delta and Gediz graben (Hakyemez et al, 1993,1999; unpublished original maps in 1:25 000 scale) * Land-use capability of the İzmir metropolitan area (MTA report / unpublished) Geohazard studies * Digitized landslide inventory maps in scale of 1:25 000 ;1:500 000 (in press/1 500 000 Scale) * Active fault map of the İzmir region in radius of 50 km and fault characterization (MTA report) * Investigation of source fault of the 2005 Seferihisar earthquakes (MTA report)

3 ONGOING AND NEAR FUTURE PROJECTS *Revision of Active Fault Map of Turkey, SW Anatolia (2007) *Cave/karst paleoseismology along the Manisa fault (2006-2007) *Investigation of submarine active faults in the İzmir and Sığacık bays/High Resolution Seismic Profilling ((2007-2008) *Geological mapping in scale of 1:25 000 of L18 İzmir Sheet (2007- 2008)

4 Status of the geological mapping in the İzmir region

5 Digitized Geological map of İzmir region (Geological Data Base)

6 Geological map of Karaburun peninsula (Çakmakoğlu ve Bilgin 2005) Original Scale/1:25 000-Geological Data Base

7 Map of the Holocene sedimentary fill in the Gediz graben and İzmir bay (Hakyemez et al.1999)

8 Distribution pattern of the Holocene facies of the Gediz delta (Hakyemez et al., 1993) Original maps are in scale of 1:25 000 Quaternary geology and geomorphological mapping
