Waveform Classification for Seismic Spectral Analysis: A Case Study Banda Aceh Earthquake

摘要

The persistent operation of a digital seismograph, now exceeding a couple of a long time in some cases, naturally includes modifications in hardware and software over time. Nonetheless, the long-term, constant overall performance of the seismic station, and the good great of its data, is very important for national seismic studies investigating the local seismicity, and also vital for the worldwide seismological neighborhood learning regional tectonics and deep Earth structures. In this study, we investigate the records availability and pleasant of the presently only seismic station on the Banda Aceh Region and Northern Sumatera. We used the Banda Aceh earthquake, June 3, 2020, with Magnitude 4.9, depth 10 km. The aim of this study to recognized and evaluate the seismic station chosen based on Continuous Wavelet Transform (CWT) and Power Spectral Density and Probabilistic Density Function (PSDPDF) for spectral analysis. The end result shown the earthquake signal detected in spectral analysis and conclude that seismic station selected has a proper overall performance history. The effects are essential for the future deployment of seismic stations on the Northern Sumatera, and for the analysis of local seismic hazard research.
