  abstract = {{G}iven the high eruption recurrence in the {M}ichoacan-{G}uanajuato volcanic field ({MGVF}) in central {M}exico, the birth of a new monogenetic volcano can be expected in the future. {I}t is important, therefore, to reconstruct the past eruptions of its many different volcanoes, including estimates of lava flow emplacement times and their rheological properties. {T}hese studies define the range of possible future eruptive scenarios and are necessary to evaluate potential risk. {T}he {R}ancho {S}eco monogenetic volcano, located in the central part of the {MGVF} (19 degrees 37'03 ' {N}, 101 degrees 28'21 ' {W}), was radiocarbon-dated at similar to 27,845 years {BP}. {I}ts eruption initiated with a violent-{S}trombolian phase that produced a scoria cone and was followed by the effusion of at least seven associated andesitic lava flows, reflecting drastic changes in the eruptive dynamics. {E}ffusive activity probably involved decreases in the magma ascent and discharge rates linked to efficient degassing in an open system. {L}ava chemical composition suggest an origin of partial melting of a subduction-modified hydrated heterogenous mantle wedge and textural and mineralogical analysis indicates significant crystal fractionation and minor assimilation of granodioritic basement rocks. {H}igh-resolution {L}i{DAR} imagery was used to estimate lava flow viscosities and emplacement times by following a morphology-based methodology. {R}esults indicate that lava flow viscosities ranged from 105 to 109 {P}a.s and emplacement durations between 32 and 465 days for the flow units considered ({F}5 and {F}6). {T}he entire eruption may have lasted from 2 to 6 years with a mean effusion rate of 4 to 15 m(3)/s. {O}ur results are also pertinent to archaeologists studying the architectural remains of {A}ngamuco, a large urban pre-{H}ispanic site built on {R}ancho {S}eco's lava flows.},
