Wildfire Susceptibility Mapping using NBR Index and Frequency Ratio Model Farzad Bolouk Heidari, Ramin Arfania Geoconservation Research, 2022 Quantifying fire hazards in natural areas and their spatial patterns are essential for developing appropriate fire management strategies, especially in countries with limited historical data on past fires. In this study, a fire hazard map for the Andika region of Iran was constructed by examining the correlation of past fires with the criteria of topography, meteorology, land cover, and human factors. The locations of eight-year fire points from 2013 to 2020 of Nova satellite sensor VIIRS were received and the fire map of each was constructed using the NBR (Normalized Burn Ratio). The wildfire events distribution maps were randomly divided into 70 and 30 percent ratios for training (modeling) and testing (validation) data, respectively. Using the frequency ratio, a fire hazard map of the region was created. Four fire hazard areas ranging from very high to low were identified. The results of past fires and the frequency ratio model showed that in the study area, land cover (2.982), elevation (2.778), and annual precipitation (2.419) have the greatest prediction rate and influence on fire occurrence. The results also showed that a large proportion of past fires (71.37%) were located in high and very high-risk areas. The evaluation results of the area under the curve method showed an accuracy of 71.1% using evaluation data and 74.4% using training data, which can be considered desirable. The small differences between the validation results using test and training data indicate an unbiased fire hazard map.
Integration of the bands of ASTER, OLI, MSI remote sensing sensors for detection of hydrothermal alterations in southwestern area of the Ardestan, Isfahan Province, Central Iran Mohammad Forouzan, Ramin Arfania Egyptian Journal of Remote Sensing and Space Science, 2020 This paper reviews the band's integration of three remote sensing sensors for improving the detecting of hydrothermal alterations. The distinguishing feature of the various minerals has always been the challenge of Multispectral sensors due to the band's limitation. On the other hand, accessibility to Hyperspectral data requires paying a high cost. Also, the narrower bands in such data and the absence of suitable data to atmospheric correction can cause more errors. So, we hope that providing more bands by this method can detect hydrothermal alteration zones correctly. The integration method acts based on the spectral offset correction on the reflectance data of the images in a log–log plot. The data include bands of ASTER, MSI, and OLI sensors in the SWIR spectral region that are converted to reflectance by 6S atmospheric correction. For the spectral method of mineral detection, we have chosen the Spectral Angle Mapper (SAM) technique. This is a powerful classification to represses the influences of shading, solar illumination, and Albedo effects. Also, we benefit from the Concentration-Area(C-A) fractal model for specifying the range of thresholds. This review emphasizes that although the integration band method can lead to the detection of minerals in hydrothermal alterations, more investigation is still needed to achieve better results because it is unsuccessful to the identification of minerals which lacking the specific spectrum peak in the range of central wavelengths of the integrated bands.
Role of supra-subduction zone ophiolites in the tectonic evolution of the southeastern Zagros Orogenic Belt, Iran Iranian Journal of Earth Sciences, 2018
Role of southeastern Sanandaj-Sirjan Zone in the tectonic evolution of Zagros Orogenic Belt, Iran Ramin Arfania, Sohrab Shahriari Island Arc, 2009 Geological studies indicate that the southeastern Sanandaj-Sirjan Zone, located in the southeastern Zagros Orogenic Belt, is subdivided transversally into the Esfahan¬Sirjan Block with typical Central Iranian stratigraphic features and the Shahrekord-Dehsard Terrane consisting of Paleozoic and Lower Mesozoic metamorphic rocks. The Main Deep Fault (Abadeh Fault) is a major lithospheric fault separating the two parts. The purpose of this paper is to clarify the role of the southeastern Sanandaj-Sirjan Zone in the tectonic evolution of the southeastern Zagros Orogenic Belt on the basis of geological evidence. The new model implies that Neo-Tethys 1 came into being when the Central Iran Microcontinent split from the northeastern margin of Gondwana during the Late Carboniferous to Early Permian. During the Late Triassic a new spreading ridge, Neo-Tethys 2, was created to separate the Shahrekord-Dehsard Terrane from Afro-Arabian Plate. The Zagros sedimentary basin was formed on a continental passive margin, southwest of Neo-Tethys 2. The two ophiolitic belts of Naien-Shahrebabak-Baft and Neyriz were developed to the northeast of Neo-Tethys 1 and southwest of Neo-Tethys 2 respectively, related to the sinking of the lithosphere of the Neo-Tethys 1 in the Late Cretaceous. It can be concluded that deposition of the Paleocene conglomerate on the Central Iran Microcontinent and Pliocene conglomerate in the Zagros Sedimentary Basin is directly linked to the uplift generated by collision.
