Urban planning is the organized planning of the physical environment that the mankind lives by providing the safety in line with the social, cultural and economical needs. The primary objective of the planning is to create healthy, reliable and durable living spaces. At this point, especially earthquakes and their effects in the countries that are located on the seismic belts of the world constitute the primary geologic threshold.

Inadequate consideration of the geohazards and the constraining effects of the geological environment or lack of precaution due to improper projection of the analysis and synthesis results to the planning and the planning decisions give rise to the increase in earhtquake damages. Geological studies aimed at reducing the effects of the ground movements due to earthquakes are of prime significance on the reduction of damage that consitutes the basis of earthquake sensitive planning studies.

Geologists, engineers, architects and planners, in creating the earthquake resistant cities, should determine the geologic hazard processes in advance and for the prevention of hazards turning into the risks and for the reduction of the damage, required precautions should take place in an interdiscplinary work. In this context, the main study is to conduct geologic and geotechnic analyses that will orient the suitability for settlement and land use decisions. The success of the damage reduction work after earthquake is proportional to the scientific base and the accuracy of the decisions.

Geological data that enable the earthquake damage reduction and are analyzed in every plan step seperately should be evaluated in coordination with the criteria of planning and design. The risks resulting from urban texture, building quality, settlement layout and macroform should also be integrated with the analyses and synthesis.
