  abstract = {{T}he {T}rans-{M}exican {V}olcanic {B}elt ({TMVB}) is a calc-alkaline volcanic arc cut by different active crustal fault systems that have originated several destructive historical earthquakes. {L}ocated in the central part of {M}exico this region offers exceptional climatic, and fertility of soil conditions, which is the reason why more than 50% of the {M}exican population now live here, increasing the seismic risk. {D}etermining the seismic potential of these fault systems is important in the western section of the {TMVB}, in the vicinity of the city of {G}uadalajara, where more than 5 million inhabitants are concentrated in a densely populated urban area. {W}e focus here on the epicentral area of the {MW} 7.2 sixteenth century {A}meca earthquake, one of the first earthquakes described to take place in the {A}merican continent and which also may be the largest crustal earthquake to have occurred in the {TMVB} in the historical record. {A}ccording to some historical sources, this earthquake would be associated with the {A}meca-{A}huisculco {F}ault but no neotectonic study has been carried out so far to characterize this fault. {H}ere, we describe the geomorphology of the fault escarpment and the characteristics of different fault segments. {T}his first step allowed to select a suitable site for a paleoseismological study to track the historic event. {T}he results of the interpretation of two trenches are consistent, showing evidence of net activity of the fault in the tectono-sedimentary record with two and possibly three seismic events. {T}he older one of these is not well recorded and interpreted as a possible event that could have occurred after 27,91 ? 0,4 cal ka {BP} and before 5,67 ? 0,064 cal ka {BP}. {T}he second one and best recorded event occurred around 5,67 ? 0,064 cal ka {BP} whilst the last one occurred after 0,985 ? 0,065 cal ka {BP} and is likely to be the geological record of the {A}meca sixteenth century earthquake. {C}onsidering the potential rupture lengths and the coseismic displacement measured in the trenches, this fault system seems capable of generating earthquakes of magnitude 6.9 to 7.3 and represents a major source of earthquake hazard to the city of {G}uadalajara.},
