As is known, earthquake waves are divided intotwo as body and surface waves. Body waves are divided into two as P and S wavesand surface waves as R and L waves. Of these waves, S and surface waves aredestructive waves. Earthquake waves propagate in rock environments with faster,higher frequency and smaller amplitudes. In addition, surface waves are noteffective in rock environments. On the other hand, earthquake waves progressslower in areas saturated with water and have low frequency and largeamplitudes. In such water-saturated soft fill areas, surface waves areextremely effective and damaging. Under normal conditions, settlement siteselection for urban buildings should be made by taking into considerationearthquake waves. However, determination of the natural radioactivity levelshould be the priority for settlement site selection in volcanic areas that arethe subject of this study. A settlement site suitable for earthquake may not besuitable for natural radioactivity. In this case, people in settlements thatare not damaged by the earthquake will be damaged by radioactive radiation.Isparta-Çünür region was chosen as the study area in order to reveal thissituation. Geologically, there are limestone, trachy-andesite belonging toGölcük volcano in the region, old and new alluvial units. Süleyman Demirel andIsparta Applied Sciences universities and Çünür district settlement areas arelocated on and around these units. Approximately forty thousand people live inthis region. Both radioactive elements with gamma-ray spectrometer andearthquake waves with multi-sources seismic refraction studies were measured soas to create a map on the geological units roughly specified. As a result ofthe studies, external hazard index values that reveal the radiological riskwere mapped in addition to the propagation velocities of earthquake waves andground classifications for suitability the settlement. As a result, it wasdetermined that the andesite hill, which is a suitable settlement in terms ofearthquake waves, is not suitable in terms of radiological risk. For thisreason, this study suggests firstly determining the natural radiological risk,especially for settlement site selection in volcanic areas.<o:p></o:p></span></p> |
