The Probabilistic Power Spectral Densities for Combination of Broadband Seismic Network

Abstract

Abstract The time series approach is commonly used to access the estimation of the power spectral densities of waveform data. This paper is concerned with the presentation of the assessment of waveform noise to measure the probability density function be done internally, we used the metadata from an inventory, a parser instance of DNP (Denpasar, Bali, Indonesia), IGBI (Ingas, Bali, Indonesia), and PLAI (Plampang, NTB, Indonesia) from BMKG IA-Networks and calculations are based on the routine used by McNamara Model. The consistency of the spectra is presented the DNP, IGBI, and PLAI network to verify the quality of data and also acts as a test performance broadband network to the time taken by the broadband network in the field and analysis the Lombok earthquake in 2018.
