“…In contrast, tectonic compression contributes to increasing the internal overpressure, but also increases the failure threshold (e.g., Galland et al, ; Watanabe et al, ), with horizontal σ 1 favoring sill emplacement. Actually, volcanic activity does not always align according to the regional stress field, as for example along the tectono‐volcanic Liquine‐Ofzqui arc fault zone spanning along Southern Chile (Cembrano & Lara, ; Iturrieta et al, ). There, volcanic eruptions are not systematically triggered by great subduction earthquakes, although this mechanism is often invoked to generate tension in this tectono‐volcanic fault zone (Bonali et al, ). The load exerted by an edifice adds a compressional component favoring lateral propagation of“ fluid‐filled cracks,” as shown by analog (Rivalta et al, ; Takada, ; Watanabe et al, ) and numerical work (Corbi et al, ; Pinel & Jaupart, ).…”

“…In spatial association with these domains, subparallel diking, ENE‐striking volcanism, and hydrothermal activity is a common feature (Cembrano & Lara, ; Lara et al, ; Melnick, Folguera, et al, ; Rosenau et al, ; Sielfeld et al, ). Furthermore, tensional stress magnitudes can be larger where NE‐striking faults are close to, or intersect, master fault segments, which enhances long‐term crustal fluid pathways during interseismic tectonic loading conditions (Iturrieta et al, ). A significant portion of the bulk transpressional deformation is accommodated by slip on the intra‐arc LOFS displaying markedly slip‐rates differences from north to south along different fault segments (Iturrieta et al, ; Rosenau et al, ; Stanton‐Yonge et al, ).…”

A significant portion of the bulk transpressional deformation is accommodated by slip on the intra‐arc LOFS displaying markedly slip‐rates differences from north to south along different fault segments (Iturrieta et al, ; Rosenau et al, ; Stanton‐Yonge et al, ). Calculated slip magnitudes from numerical models may be larger along pure strike‐slip fault segments, ranging from ~18 mm/year, close to southern LOFS termination (Iturrieta et al, ), down to 0.5 mm/year in the northern termination (Stanton‐Yonge et al, ; Figure ).…”
