The Western Ghats (WG) is one of the great escarpments that extend ~ 1500 km parallel to the west coast of India in the NNW-SSE. We deployed a network of seven broadband seismological stations along the WG to decipher it’s evolution. In the present study, we investigate the characteristics of different kinds of noises at the stations by utilizing the power spectral density measurements. Further, the results are compared with the global standard noise models to assess the data quality. The PSD results reveal that the short period (cultural) noise is more prominent at stations AGMB, SDPR, MGLI when compared to the other stations, especially during day hours since these sites were in the proximity of roads. The seasonal variations are observed especially in the microseismic period range and noise levels are more prominent in the months of July to August since the western part of India experiences peak monsoon during this period. These variations are observed especially at PCH and KNUR stations as their locations were near the coastline. Further, the results indicate that the noise levels are more prominent in vertical component than that of horizontal components in the microseismic period range whereas it is reversed in the short and long period ranges. Later, the results indicate that the noise levels at all the localities of stations are within the global standard noise models, which suggest that our installation of broadband seismological stations have been successful and has good data quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
