This study aims to develop a landslide susceptibility map for the mountainous regions of Tehran province, Iran. The rock engineering approach was employed at a regional scale, utilizing a database of regional landslides. The semi-quantitative Rock Engineering System method was applied, considering 10 conditioning factors. The model was validated using historical landslide data, showing strong correlation. The majority of landslides occurred within medium and high susceptibility zones. Geological units, particularly the Karaj Formation's claystone layers, displayed a clear association with landslide susceptibility. The rock engineering approach yielded a highly accurate susceptibility map. Findings can inform future territorial planning in the area.","PeriodicalId":22260,"journal":{"name":"Terra Nova","volume":"9 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138716891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To what extent basement faults were involved during its deformation is a matter of debate. We use 3D seismic data to investigate the deformation style along the easternmost tip of the Jura range in unprecedented detail. Here, basement-rooted normal faults were not only repeatedly reactivated before thrust belt formation but also contemporaneously active as reverse/transpressional faults. They either propagated up into the Mesozoic succession without interruption (‘hard linkage’) or apparently controlled the localisation of Mesozoic faults via smaller-scale shear zones (‘soft linkage’). Our analysis of the resulting fault geometries questions the existence of a large-scale basal detachment in this area and points out the importance of thick-skinned fault reactivation.","PeriodicalId":22260,"journal":{"name":"Terra Nova","volume":"38 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138716890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the quantitative relationships between the orientation of these remnant faults, plate bending and seismic activity at subduction zones still remain unclear. Here, we investigated the flexure of the Alaska subducting plate and assessed the relations between plate flexural curvatures, trench–fabric angle and seismicity. The results show that the flexural curvature and seismicity have nearly linear relationships with the trench–fabric angle. We find that remnant faults are more likely to be reactivated by plate bending at low trench–fabric angle region, causing greater plate deformation, hydration, weakening and seismicity. Plate weakening in turn promotes flexural bending curvature, resulting in higher degree of fracture and more earthquakes. However, at the high trench–fabric angle region, it is inclined to form new trench-parallel bending faults that have smaller bending curvature and less seismicity.","PeriodicalId":22260,"journal":{"name":"Terra Nova","volume":"28 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138530894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we integrate fault morphology, InSAR measurements, and high-resolution bathymetry to quantitively evaluate potential future tsunami sources and tsunami wave characteristics. We systematically investigate how earthquake rupture speed and direction could affect tsunami hazards for the Makran region. Our analyses reveal the following new understanding: (1) The estimated maximum slip deficit in the Makran region southeast of the Gwadar port is >4 m since the last significant 1851 rupture; (2) Earthquakes with finite rupture speed investigated in the range of 300–1,000 m/s are calculated to generate higher tsunami waves than the static rupture model; (3) For an east-to-west rupture direction, the tsunami waves are calculated to arrive at the Gwadar port 3–5 mins later but with higher waves than the static rupture model. Together, our results highlight the importance of the source earthquake rupture speed and directivity in controlling tsunamigenic effects.","PeriodicalId":22260,"journal":{"name":"Terra Nova","volume":"74 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138530890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Measurement of Rn degassing at the active faults was conducted twice in 2017 and 2018 to assess fault activity in the western margin of the Ordos block. The concentration and flux values of Rn ranged from 0.41 to 40.93 kBq m<sup>−3</sup> and 5.17 to 140.33 mBq m<sup>−2</sup> s<sup>−1</sup>, respectively. The compression of the Tibetan Plateau has led to higher Rn concentration and flux in the southern part compared with the northern part. The fault activity is evaluated by the index of <i>I</i><sub>Rn</sub> calculated from Rn concentrations. The Haiyuan arcuate tectonic region exhibited the most intensive fault activity, followed by the Yinchuan Basin and Jilantai-Linhe Basin. These findings enhance our understanding of the relationship between fault activity and Rn emission and provide a significant geochemical reference for the fault activity.","PeriodicalId":22260,"journal":{"name":"Terra Nova","volume":"42 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138530888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These data indicate that the Internal Ligurian units were affected by a blueschist facies metamorphism achieved during the underplating within the accretionary wedge developed during the Late Cretaceous—Early Tertiary Alpine subduction.
