Geotechnical conditions and seismic hazard analysis for architecture heritage preservation in Peru: The Andahuaylillas Church case study

This paper presents the results of a geotechnical and geophysical tests and a Deterministic Seismic Hazard Assessment (DSHA) carried out for the San Pedro Apóstol de Andahuaylillas church in Peru, also known as the Sistine Chapel of the Andes for its magnificent paintings. The DSHA is one of the key components of the ongoing seismic vulnerability study led by the Engineering and Heritage research group of the PUCP University, in Lima, Peru. This structural seismic vulnerability study is motivated primarily because of the historical, architectural and artistic features of this church, built circa the late 16th or early 17th century, which was declared part of the Cultural Heritage of Peru in 2010. The DSHA study for this monument is also important because this church is representative of a large number of adobe colonial churches built during the baroque period in this region of the Andes with similar seismicity.
