    • Tectonics
    • Geodesy
    • Local and regional seismicity
    • Seismology of the earthquake sequence
    • Evaluation of strong ground motion recordings
    • Tsunami
  • Geotechnical aspects of the 2023 Kahramanmaraş earthquake
    • Landslides and rockfall
    • Surface rupture and interaction with structures
    • Liquefaction and subsidence
    • Bridge foundations and approach structures
    • Retaining structure
    • Limiting distances for ground effects
  • Structures
    • Evolution of the Turkish building codes
    • Building stock and damage assessment
    • Prevalent building typologies and observed seismic performance
  • Remote sensing
  • Infrastructure
    • Healthcare infrastructure
    • Educational infrastructure
    • Emergency response infrastructure
    • Transportation infrastructure
    • Energy infrastructure
    • Industry infrastructure
    • Water and wastewater (wwt) infrastructure
