SISTEM INFORMASI DAN ANALISA GEMPABUMI MENGGUNAKAN JISVIEW PADA STUDI KASUS GEMPABUMI TASIKMALAYA

Abstract

Java Island has an interesting tectonic system to study, especially since this region is formed from plate collisions that cause the formation of subduction zones. Because of the uniqueness, earthquakes often occur in this region, which one of them became the attention of researchers, namely the Tasikmalaya earthquake on December 15, 2017. The purpose of this study is to analyze the earthquake recording signals and also the pattern of focal mechanisms of the Tasikmalaya earthquake from processing result of JISView (BMKG) devices that have been validated with comparators from GFZ (Germany) and USGS (United States) websites. The method used is to make an analysis of the wave signal caught by the recorder station and then identify the results of the parameters generated on the calculation of the device and match the data obtained with data tectonic structure around the area of the earthquake zone. Based on the results of data processing, the intensity value of earthquake signals obtained from the processing in accordance with the data released by BMKG agencies and earthquakes from the depth of 90-110 km which occurs due to the shift of the fault, with the type of fault is strike-slip fault (dextral), where the cause of the earthquake comes from the subduction zone (benioff zone in the deep background).
