Earthquake risk identification and analysis in rural areas is the decisive factor in the reduction their damages and casualties. Because in the cycle of crisis management, planning and identification of rural settlements risk is necessary to achieve the waste resources prevent policy and utilization of the maximum power. In other words, many of the villages risk in the earthquake, is preventable with causes recognition and reduction of vulnerability roots.Therefore this study pays to discuses and analysis of the earthquake risk in the rural settlements of central District of Marand County with the descriptive- analytic methodology. The population of this study is consisted of 74 villages in the central District of Marand County, that all of them have been studied. To assess earthquake risk in study area, initially the earthquake risk assessment model was presented in rural areas based on the conceptual and operating framework and then weighting to the indexes using the academic professionals (30 analytical hierarchical process questionnaire) and data process in the GIS environment, indexes of exposure (using GIS analysis) and vulnerability (with using of TOPSIS technique) was calculated. It should be noted that, each of the parameters was measured and modeled within several indicators and finally, using of layers overlay analysis in the GIS, earthquake risk assessment was conducted in the study area. According to the results, about 32 percent of the studied villages are located in high and very high risk zones that raised the necessity of planning, based on principles of crisis management.

Housing as a heterogeneous product, lasting, immovable and assigning is the main part of family budget. In other words, the housing as one of the main goods not only contains use value in its nature but also is considered as an investment in which selection of the price has main role. Therefore this article attempts to explore the affecting variables on housing prices in the Sahand new town. The research method is correlation test and the use of hedonic function. The results showed that the factors like lot size and building area, number of floors and the number of apartment in per floor among the physical and spatial factors’ distance to nearby park and green space, distance to nearby shopping center have the highest effect on housing price. The correlation analyses used were Spearman and Kendal methods. These analyses only used for spatial factors. Results showed that there was straight correlation between the price and nearby mosques, which means the price arises when it is far away from the mosque.

Alluvial fans as one of the major geomorphological forms of water reservoir are very important, such that most of urban and rural centers of Iran, especially in central and eastern sections are located on alluvial fans. They are usually controlled by geomorphological forms of tectonic activity along with climate change. Alluvial fans are located in the southern half of the drainage basin of Birjand. Due to their proximity to the city and the residential areas, they are very important. BagheranMountains in the south part of Birjand are part of Sistan area. The most important rock units in the upper Cretaceous include ophiolitic mixture, flysh, congelomerate and the oldest unit is related to that era. In this study the geomorphology evidence of the area has been used to investigate the morphotectonic activity. In order to do this purpose, we used sime indices. Review of the samples of sediment aggradation and drainage network on alluvial fans show how climate and tectonic have influenced them. Field observations and sediments granolometry have been used for this purpose. The results of the analysis also show young tectonics and dynamic processes of external activities intensity performance in the region. Also granolometery analysis of the area as evidence of tectonic activity result in alluvial fans landforms transitional to the bajada plains indicated that climate change and wind erosion have higher intensity on landforms.

The aim of this paper is assessment and comparison of potential impacts of climate change on drought indices in an arid and a semiarid station. For this purpose, daily data of minimum and maximum temperature, sunshine and precipitation are used. This data were downscaled statistically by using LARS-WG model based on A2, B1 and A1B scenarios. These climatic parameters are projected for 2011-2040, and RDI index was extracted for both observed (1961-1990) and projected data from HADCM3 model. The research outcomes show drought severity has increased under each scenario in both stations, except for Shahrekord under B1 scenario. For Bandarabbbas station, percent of droughts are about 6.7, 10 and 10 under A1B, A2 and B1 scenarios respectively. This parameter is 6.7 and 3.3 percent under A1B and A2 in Shahrekord station and the number (percent) of droughts will decrease about %10 under B1 scenario in this station.

One of the important arguments in variability and climate change assessment is the accuracy of climatic time series analysis. Therefore time series to be used should be homogeneous. Annual and seasonal maximum and minimum temperatures of 5 synoptic stations that contain long time series have been assessed in this study. For so doing, we utilized direct and indirect methods. We used metadata through indirect method and absolute and relative standard normal homogeneity test through direct routine. Results showed inhomogeneity which was identified by statistical methods corresponding to metadata. Relative standard normal homogeneity test is more suitable than absolute standard normal homogeneity test in this concern. Assessment of homogeneity between annual and seasonal minimum and maximum temperatures indicates that the parameter of minimum temperature has more inhomogeneity in the data. Comparison of homogeneity results between temperature of warm and cold season reveals that the temperature is more stable during relocation and other changes in cold season than in warm season. Relocation of many stations was not proved to be the cause of inhomogeneity in annual and seasonal maximum temperatures.

Physical expansion of Tabriz metropolitan increases the possibility of earthquakes risks. Given the importance of this issue, this research is trying to pay to monitor the activities and seismic potential of Tabriz fault and the estimates of casualties in Tabriz metropolitan using remote sensing and GIS techniques. To achieve this goal, ASTER satellite image was processed in ENVI 5.3 software. Fault seismic potential is determined with empirical models and average calculations were used as the basis for assessment. The casualties are determined in accordance with the terms of seismicity and structure of our country urban elements, respectively. Based on visual interpretation of satellite data, along Tabriz fault are exposed geomorphic changes that reflect the tectonic activity is in the range of Tabriz metropolitan. Tabriz fault evidences examples of diversion of watercourse Ajichai, cliffs and lens shape phenomenon are most important that have been considered in the interpretation of the activities on satellite images. Based on empirical models, be created in Tabriz fault earthquakes is average of magnitude 6.8 on the Richter scale. Assuming earthquake seismic activity according to Tabriz fault scenario, the total population of about 1605884 of the Tabriz metropolitan was estimated approximate number 1252589 casualties consist of 658412 people dead and 594177 people injury at night

Precipitation is one of the most essential and variable climate components whose understanding has long been a concern for climatologists. The main objective of the current paper is to investigate and analyze the precipitation cycles in Iran. In order to realize this objective, the annual precipitation data of isometric station of Iran were extracted. These data have been collected by the country’s meteorological organization since the establishment of the station until 2008 which adds up to more than 40 years of statistics. Then, in order to investigate and analyze the precipitation cycles, spectral analysis (co-structural analysis) was utilized. Regarding the calculations, the programming utilities of Matlab were used and the Surfer software application was exploited for drawing operations. The results obtained from analyzing the cycles show that there are significant 2 to 3 year cycles, 3 to 5-year cycles, 2 to 6 year cycles and sometimes 11 or more- year cycles governing Iran’s precipitation patterns. Hence, in east and southeast of Iran, 3 to 5-year cycles are prevailing and in west and northwest 2 to 3-year cycles are dominant and finally in north east 2 to 6-year cycles are customary. The most numerous and the most variable cycles happen in south and south east, mainly due to the mountainous regions of Zagros as well as the proximity to Persian Gulf. The north western regions, much like the southwestern regions, indicate variable cycles due to the mammoth mountains of Sabalan and Sahand. Moreover, the presence of those cycles which have a return period equal to the statistical period has been seen in various parts of Iran, which indicates a precipitation trend in this country.

Elections are the process that citizens can criticize and monitor the politicians and governors. In fact, the elections are the most appropriate democratic way in which the citizens can be interfered in the choosing of government operators. At the same significance, political geography is going to study and analyze the relation between election and geographical environment in order to conduct the geography of elections into the description of the general patterns of politics and recognition of the process of the government establishment. In this paper, we have studied the effective factors in the victory of, the Candidate of Kazeroun City in the 9th Period of the Iran’s Islamic Parliament Elections. The methodology of the paper is descriptive- analytic. The results of the research show that among the various theories about the sources of poll, composition of Inglehart, Pippa Norris and Chicago give a holistic opinion to studying of the elections. Therefore, in the case of Kazeroun City, it seems that three factors of political experience in the past, economic-social basin and the scheme of political system in the frame of biological foundations played the most roles in the poll of Kazeroun City’s candidate in the 9th period of the Iran’s Islamic Parliament Elections.

Geo-tourism is a combination of geography and tourism. In this sense, geo-tourism encompasses biodiversity, cultural diversity, beautification, community-based tourism, and even local food movement, and homogeny and similarity are considered its enemies. Geo-tourism is a form of tourism which is defined to ensure the establishment and improvement of geographical features such as the environment, culture, landmarks and legacies and well-being of residents. With this approach, Deira catchment area in Gilangharb Township located in 215 km of Kermanshah, was chosen because of its natural resources for Geo-tourism assessment and was analyzed according to obtained data from library and literature studies and field studies using Pereira. Although the region attracts hordes of tourism annually, yet its economic position in tourism industry is not founded. In this research we try to assess Geo-tourism capabilities related to available landforms in the region in addition to identify geomorphological shapes and forms in the region and explore its features. The results of this study showed that the geomorphic location of Galin has high capability in the field of tourism attraction with 345/5 geomorphology value and managerial value of 5 in Deira catchment area. The geomorphological shapes and forms of the region have high capability in the field of tourism due to high ability in the field of geosciences education, and feature and attributes such as beauty, ease of access, and natural and cultural attractions.

Earthquake is a serious threat for society development and its vulnerability is influenced by environmental variables. The damages of earthquakes are reduced by recognizing these variables and area zoning. The aim of this paper is the zoning of earthquake vulnerability of Sanadaj city based on effective variables. For this purpose, the final map of region’s natural vulnerability zoning and skeletal indices and other effective social indices have been used. The variables were changed to layers of GIS and then, overlapping were performed using AHP and TOPSIS models. Finally, the vulnerability was classified in five groups from very low to very high. By comparing the results of these two models, it was revealed that these models had a similar vulnerability but they had a difference in which based on AHP model, the regions with very high vulnerability have little fragmentation in contrast with TOPSIS model. Therefore, according to AHP the most fragmentation was occurred in regions with low vulnerability. While, based on TOPSIS, the regions with average vulnerability have the most extension. According to Both models the most vulnerable areas were in the north of Sanandaj city.
