  abstract = {{T}he {A}tacazo-{N}inahuilca {V}olcanic {C}omplex ({ANVC}) is located in the {W}estern {C}ordillera of {E}cuador, 10 km southwest of {Q}uito. {A}t least six periods of {P}leistocene to {H}olocene activity ({N}1 to {N}6) have been preserved in the geologic record as tephra fallouts and pyroclastic flow deposits. {N}ew field data, including petrographic and whole-rock geochemical analyses of over forty soil and tephra sections, 100 pumice and lithic samples, and 10 new {C}-14 ages allow us to constrain: (1) the tephra fall isopachs and detailed characteristics of the last two events ({N}5-{N}6) including volume estimates of the tephra and pyroclastic flow deposits and the corresponding volcanic explosivity index ({VEI}); (2) the petrographical and geochemical correlations between domes, tephras, and pyroclastic flow deposits; and, (3) the timing of the last 4 eruptive events and a period of quiescence that endured a few thousand years (1000-4000). {T}he last two eruptive events ({N}5 and {N}6) took place at around 4400 +/- 35 yr {BP} and 2270 +/- 15 yr {BP}, producing huge plinian and pyroclastic flow deposits. {T}aking into account the widely spread deposits of these {VEI} 5 eruptions, the present population of about 70000 people, and the current infrastructure; the development of mitigation plans and deployment of monitoring systems at {ANVC} is highly recommended.},
