Babol, as the second most populous city of Mazandaran province in northern Iran, is exposed to earthquakes due to its proximity to two active faults, the Caspian Sea and northern Alborz. The purpose of this study was to evaluate the effective physical indicators in the resilience rate of 22 neighborhoods of Babol. The research method is descriptive-analytical and applied-developmental. Accordingly, 48 effective indicators in the physical dimension were extracted and evaluated for their suitability through KMO test in consultation with experts and professors in urban planning, crisis management and earthquake. Then, the selected indices were reduced to four factors by factor analysis, which accounted for 61.9% of the variance. Among the four factors, the first factor alone accounted for 24.8% of the variance, which SHOJAEE, M. et al.

Cluster analysis was used for homogeneous classification of the neighborhoods and Babol's 22 neighborhoods were classified into 8 homogeneous groups. The results of clustering method show that about 40.9% of neighborhoods are evaluated as very poor, poor and relatively poor and in undesirable conditions in general. Also, about 18.2% of the neighborhoods are in the medium level and about 40.2% of the neighborhoods are evaluated as good, very good, excellent and very excellent levels in terms of physical resilience.","PeriodicalId":41550,"journal":{"name":"Geosaberes","volume":"11 1","pages":"364"},"PeriodicalIF":0.0,"publicationDate":"2020-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45267135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lithologic composition of the volcanic rocks in the area consists of andesite, basalt, trachyandesite and quartztrachite. Plagioclase, olivine, and augite phenocrysts as the main minerals and apatite and magnetite, sericite, chlorite and apacite minerals are sub-minerals of volcanic rocks that are located in the glass slabs. Quartz is also found in fine-grained rock pulp and sometimes in phenocrysts. The dominant texture in these rocks are porphyritic, amygdaloidal and microlithic. According to geochemical studies of basaltic magmatic volcanic rocks, calc-alkaline potassium is high and negative Nb anomaly, Ce / Pb ratio and enrichment of rocks of light rare earth elements (LRRE) and high LREE / HREE ratio indicate contamination. The crust is an indicator of the presence of the garnet phase in the mantle source. On the other hand, the similarity of their trace elements to Oceanic Basalts (OIB) is a clear evidence of their relevance to this environment. Early basaltic magma originated from a mantle with a garnetlherzolite composition with a partial melting rate of 15–12%. FeOtotal values in basalts and other structural evidence indicate the formation of these rocks in the early stages of intra-continental rifting which can be attributed to the pressure drop caused by intra-continental tidal phases associated with deep faults during the orogenic phases.

Based on the initial study, it was found that the three factors of geological materials, slope, and climate are the most important factors in erosion. Therefore, these three factors were examined and combined to create work units. Then, the qualitative sensitivity of the rocks and pre-Quaternary formations was continually determined using the criteria of resistance method and hardness of the rock mass in a field method. Then, several statistical regression models were investigated by discharge classification and temporal separation of data; and by establishing a regression relation between flow discharge and sediment MIRAKHORLO, G. et al.

Thus, the study indicated that the basin area studied is 10122.4 km2 and a perimeter of 757.03 km2. In turn, the basin has an elongated profile and low predisposition to abrupt flooding, as its compactness coefficient is 2.1068, form factor 0.12 and circularity index of 0.222.
