  abstract = {{K}nown worldwide for its rich and well-preserved pre-{C}olumbian and {S}panish architecture, the city of {C}usco ({P}eru) is listed as a {W}orld {H}eritage {S}ite since 1983. {H}owever, less well known is the seismic hazard, which represents a major threat to the city's 400,000 inhabitants and its cultural outreach. {D}espite the moderate magnitudes recorded in the area, macroseismic data inferred from historical earthquakes (1650, 1950) argues for strong amplification effects of the unconsolidated sediments of the {C}usco {B}asin during ground motion. {I}n order to address this aggravating factor for the first time, we conducted a large-scale passive geophysical survey in the historical city center of {C}usco, combining {M}icrotremor {H}orizontal-to-{V}ertical {S}pectral {R}atio ({MHVSR}) measurements and {M}icrotremor {A}rray {M}easurements ({MAM}). {T}hrough joint data inversion, we proposed a subsurface wave velocity model and estimated the depth of the engineering bedrock. {T}he site response analysis not only provides an insight into the thickness of the soft sediment, but also suggests the existence of a strong geological discontinuity beneath the city center of {C}usco, consistent with the trace of the {C}usco fault. {M}oreover, the results highlight the complexity of earthquake site amplification assessment in dense urban areas. {O}ur work paves the way for a comprehensive seismic microzonation of the entire {C}usco {B}asin and opens up new perspectives on the potential of the {MHVSR} method for fault detection.},
