The study aims to investigate the effects of Burdur (Turkey) marble on human health by interpreting their radioactivity concentration (²²⁶Ra, ²³²Th, and ⁴⁰K), radiological hazard parameters, chemical concentration, physical properties, and all data related to these features by using multivariate statistical methods. Chemical and radionuclide analyses were performed on marble samples. The data were interpreted by statistical analysis. According to the regression model, an increase in the concentration of vanadium carried to the environment by hydrothermal waters causes a 4.452-fold higher concentration of ²²⁶Ra. The R² value of the model was 0.64 and it was statistically significant. The maximum concentration of ²²⁶Ra in Isparta Davraz Beige sample (M7) exceeded the values of some countries’ standards. Except for M7, the analyzed sorts of marble can be used safely in dwellings and public buildings.

Elmalı Basin, which consists of the Elmalı county and some villages, approximately 120 km far from Antalya city, is one of the recent depositional areas in the extensional neotectonic region of southwestern Turkey. The basin provides significant data for the understanding of the geological evolution to record from the basement to recent depositional units. For this reason, these kinds of structures are used to determine the deformations phases for the evolutionary history of basin formation. In the content of the study, following applications have been investigated: (a) mapping of the area and structures in 1/25.000 scale, (b) information about deformation and tectonic activity along the basin margin faults, (c) the distribution of peak ground acceleration (PGA) in case of an earthquake with 6.5 magnitude and (d) morphometric analyzes of the basin to understand the tectonic upift by using the digital elevation model. The new results combined with existing data imply that the Elmalı Basin has a number of deformation structures and active faults on both western and eastern sites of the basin. Depending on the morphometric indices, western site of the basin created higher uplift ratio compared with the eastern site of the basin.

Damage to structures during earthquakes may be fully or partly caused by soil liquefaction, which has been the subject of extensive research for several decades. Liquefaction susceptibility of a sandy deposit is performed by comparing the resistance of a soil to liquefaction (i.e., capacity) to the load imparted by an earthquake (i.e., demand). In this regard, the stress-based method of liquefaction assessment is by far the most popular. It involves uncertainties mostly related to the computation of the maximum horizontal ground acceleration (a_max) at bedrock. A site response analysis or a simplified assumption is necessary to determine the a_max on the ground level as well. Developing from the stress-based approach, the strain-based approach has also similar constraints. There exist laboratory techniques such as torsional shear to determine the capacity of a sandy soil in terms of liquefaction energy per unit volume. Likewise, the energy of a strong motion record can be set by employing simple physics principles. For this, a velocity time history and the unit mass of the soil are employed to compute the demand of any strong motion record. The scope of this investigation is to illustrate the usability of the energy-based method for the evaluation of soil liquefaction. The deficiencies of the stress- and strain-based approaches are outlined and the advantages of the energy-based approach are discussed.
