Dynamic characterization of Nepali Masonry Temples hit by 2015 Earthquake

The objective of this work is present the results of ambient vibration measurements obtained in two different Nepal missions (October 2016 and October-December 2017). The object of the research is the comparison of the dynamic behavior, through the measurement of the ambient micro tremor, of two monumental Hindu masonry buildings (Jagannath Temple and Pancha Deval complex) damaged by the 2015 Gorkha earthquake. The methodology used involves a meticulous study of the building through visual inspection and the use of a tromograph for the survey of structures in elevation. The results obtained show, in the case of Jagannath temple, a relationship between the high level of damage and the asymmetrical disposition of the roof beams. In the case of Pancha Deval complex, the AVMs show an interaction between the structure and the ground.
