  abstract = {{T}wo well-dated delta 18{O}-speleothem records from {S}hatuca cave, situated on the northeastern flank of the {P}eruvian {A}ndes (1960 m asl) were used to reconstruct high-resolution changes in precipitation during the {H}olocene in the {S}outh {A}merican {S}ummer {M}onsoon region ({SASM}). {T}he records show that precipitation increased gradually throughout the {H}olocene in parallel with the austral summer insolation trend modulated by the precession cycle. {A}dditionally the {S}hatuca speleothem record shows several hydroclimatic changes on both longer- and shorter-term time scales, some of which have not been described in previous paleoclimatic reconstructions from the {A}ndean region. {S}uch climate episodes, marked by negative excursions in the {S}hatuca delta 18{O} record were logged at 9.7-9.5, 9.2, 8.4, 8.1, 5.0, 4.1, 3.5, 3.0, 2.5, 2.1 and 1.5 ka b2k, and related to abrupt multi-decadal events in the {SASM}. {S}ome of these events were likely associated with changes in sea surface temperatures ({SST}) during {B}ond events in the {N}orth {A}tlantic region. {O}n longer time scales, the low delta 18{O} values reported between 5.1-5.0, 3.5-3.0 and 1.5 ka b2k were contemporaneous with periods of increased sediment influx at {L}ake {P}allcacocha in the {A}ndes of {E}cuador, suggesting that the late {H}olocene intensification of the monsoon recorded at {S}hatuca site may also have affected high altitudes of the equatorial {A}ndes further north. {N}umerous episodes of low {SASM} intensity (dry events) were recorded by the {S}hatuca record during the {H}olocene, in particular at 10.2, 9.8, 9.3, 6.5, 5.1, 4.9, 2.5 and 2.3 ka b2k, some of them were synchronous with dry periods in previous {A}ndean records.},
