The Andean Southern Volcanic Zone (SVZ) concentrates many of the most active volcanoes continental arc, as well region’s recent and impactful volcanic eruptions. In this contribution, we briefly revise general characteristics SVZ volcanism provide a synthesis scientific findings related to latest eruptions (430 peer-reviewed publications with over 9,000 citations, large-magnitude (VEI 4-5) being studied. Our study shows that research has been primarily focused on environmental atmospheric impacts (29%), eruption descriptions physical volcanology (20%), hazard risk assessments (15%), other investigations complementary volcanology. Whereas least silicic (e.g., Llaima 2008-2009 Villarrica 2015) shed light magma replenishment degassing dynamics controlling styles, intermediate (andesitic-dacitic) offered clues either rapid or slow initiation, relevant phreatic-to-magmatic style transitions triggering mechanisms. On hand, (i.e., rhyolite-rhyodacite) provided unique observations ascent, high-rate extrusion, rheology, fragmentation processes, transitions. These have also inspired new generation tephrochronological, tephrostratigraphical, studies, aimed at assessing long-term (kyr-scale) evolution systems their associated hazards. We debate how knowledge gained from human coexistence are reducing in SVZ. Finally, discuss challenges opportunities emerging disciplines can complement our understanding region.
