Abstract

Province of West Papua has large territory and active tectonics. It requires seismic stations to determine the location of the earthquake, it important to recognize the effects of adding seismic stations on proccessing earthquake parameters and the seismic pattern of the region of West Papua Province. Using earthquake analysis data from earlier seismic stations (SIJI, SWI, MWPI, RKPI, FAKI and RAPI) and recent seismic stations (STPI, TSPI, and IWPI). This study used Seiscomp3 software to determine earthquake parameters and GMT (Generic Mapping Tool) version 5 to plot epicenter. The datas are earthquake events at 19th March 2020, 24th April 2020, 26th April 2020, 27th April 2020, 28th April 2020, the epicenter of earthquake events from the period June 2019 to January 2020 (before the recent seismic stations was installed) and from the period February 2020 to May 2020 period (the recent seismic stations was installed). Then we applied quantitative methods and comparing the data. The results are: the recently seismic stations can effect the analyze of earthquake parameters by looking at the value of the RMS Error factor, Azimuth gap, latitude error and longitude error, this study found increasing earthquake events and new cluster eartquakes after added recent seismic stations. We should install more new seismic stations to get accuracy of earthquake parameters and we need related advanced studies.
