The Characteristics Influence of The Seismic Signal Noise Using Spectral Analysis

The observation of earthquake monitoring station had deployed in Indonesia. The data for this study were earthquake data recorded from BMKG Seismic Network. We use the 2016 Aceh earthquake, struck the Indonesia Island of Sumatra with Mw of 6.5 in Aceh province on December 7th 2016, at 05:03 WIB (22:03 UTC December 6th 2016) with duration 14 days from December 1st 2016, 00:00:00 UTC to December 14th 2016 00:00:00 UTC. Spectral analysis response to determine the level of background noise in the seismic station by using the Power Spectral Density and the Probability of Density function from the spectral result. The results of our background noise analysis are useful for characterizing the performance of existing BMKG Network Station, for detecting operational problem. (paper)
