== Abstract ==

The paper describes in detail the application of a vibration-based structural health
monitoring system installed in the “San Pedro Apostol” church of Andahuaylillas located in
Cusco (Peru), a 16th century adobe church considered a representative example of South
America baroque architecture. The results of three years of long-term vibration and
temperature and humidity monitoring program are reported in detail in the paper, with a focus
on the long-term and short-term correlations between natural frequencies and environmental
parameters. The results demonstrate that an accurate estimation of the first eight frequencies
in the range 2-6 Hz is possible in the case of complex adobe structure and the existence of an
annual cyclical behavior of the natural frequencies with a clear correspondence with the
changes in environmental conditions due to seasonal influences. The performed correlations of
ambient conditions and structural parameters confirmed the presence of different timescales
and their not negligible influence in the case of a vibration-based structural health monitoring
assessment of adobe systems with large thermal inertia large thermal inertia.
