5.1 Timing, Architecture, and Kinematics of Deformation sopra the Soddo Reparto
The plan view architecture of the Soddo margin is characterized by a typical array of sigmoidal, right-stepping en-echelon normal or oblique faults (Figure 5)
Durante order sicuro better characterize the distribution of vents durante the dipartimento and esatto better define their relations with faults, we have mapped vent alignments and assessed their reliability according puro the procedure illustrated con Paulsen and Wilson [ 2010 ]. Vent mapping has been performed on available corpo celeste images (Landsat TM, Aster, Google Earth imagery), digital elevation models (DEMs; SRTM, Aster), and aerial photos. Con particular, vent alignments have been mapped on the basis of the spatial distribution of vents as well as their shapes (vent elongation provides per critical parameter puro group solo vents into an alignment). Reliability of vent alignments has been defined according onesto parameters such as number of vents, number and characteristics of elongate vents (vents are considered elongate when the ratio between the lengths of the maximum and minimum axes is >1.2), canone deviation from verso best fit line, etc. [see Paulsen and Wilson, 2010 ]. The result of this analysis is illustrated sopra Table 3 and in the graph of Figure 12d, where the azimuthal distribution of elongate vent long axis has also been reported. The distribution of both vent alignments and elongate vent long axis shows per main peak at N20°–25°Addirittura, indicating per striking correspondence with the tendenza of the border faults sopra the dipartimento (compare Figure 12d with Figure 5c) and thus strengthening the close relations between faulting and volcanism. Esatto complete the analysis, we have http://www.datingranking.net/it/fitness-singles-review/ also calculated the azimuthal distribution of cone breaching, whose results are shown in the graph of Figure 12e. This analysis indicates that the tendenza of cone breaching tends preciso parallelize vent alignments (as well as the andamento of border faults), with a minor peak orthogonal esatto this latter inclinazione.
