The detection of active faults around volcanoes is of importance for both seismic and volcanic hazard assessment. The lower flanks of volcanoes are, however, often covered by debris avalanche deposits (DADs) that are highly faulted during transport. Such areas are dissected by faults that delineate deposit hummocks, making it hard to differentiate tectonic from landslide structures. Detailed an...

driven erosion could govern tectonic deformation has instigated a decade of geodynamic models and geological studies 5 that explore potential climate–tectonic feedbacks. According to this idea, erosion of mass from Earth’s surface may determine where tectonic deformation is most rapid. Consequently, heavy precipitation, rapid erosion and active faulting are predicted to be spatially correlated ...

the study area is the rahmat anticline. this is located in fars province (sw fold simple zagros belt). the aims of this study are morphotectonic studies and structural analysis in several parts of area. for this purpose: 1) morphotectonic indices, drainage basin shape index (bs), mountain front sinuosity index (smf) and valley floor width – height ratio (vf) were measured by digital elevation m...

in taleghan, olivine basalt-basaltic andesite dykes as part of tertiary mamgmatic activities in central and western alborz zone, intruded into both karaj formation and late eocene-oligocene volcanic rocks. these dykes have similar geochemical characteristic which suggest that they are originated from a common source. on the primitive mantle normalized spider diagram, the dykes are characterized...

The Alboran Basin and the surrounding Betic-Rif Cordilleras (see Fig. 1) constitute an arc-shaped thrust-belt that exempli®es contemporaneous internal extension and frontal thrusting in an overall compressional setting. The complex tectonic evolution of the region is the result of ongoing convergence between Africa and Eurasia since late Mesozoic. Until the amalgamation of Iberia with Europe, f...

Changes in seismicity rates, whether of tectonic or of induced origin, can readily be identified in regions where background rates are low but are difficult to detect in seismically active regions. We present a novel method to identify likely induced seismicity in tectonically active regions based on short-range spatiotemporal correlations between changes in fluid injection and seismicity rates...
