This paper presents an analysis of volcanic lineaments in West Java using the application of modern cartography and computational geophysics. The condition of this area is very complex due to overlapping volcanic activity since millions of years ago. Volcanic baseline data from the Global Volcanism Program (GVP) is used as a reference by validating volcanic data from satellite data (Google Earth); High resolution Digital Elevation Model (DEMnas) from the SRTM Global and Geospatial Information Agency. A geophysical review using very high resolution GRACE satellite gravity data was applied to visualize regional (deep) and residual (shallow) subsurface models. The visualization results will be useful for further studies and support regional tectonic studies of the Java subduction zone.
Makalah ini menyajikan analisis kelurusan gunungapi di Jawa Bagian Barat menggunakan aplikasi kartografi modern dan komputasi geofisika. Kondisi area ini sangat komplek akibat aktivitas gunungapi yang saling tumpang tindih sejak jutaan tahun yang lalu. Data dasar gunungapi dari Global Volcanism Program (GVP) dijadikan referensi dengan validasi data gunungapi dari data satelit (Google Earth); Digital Elevation Model resolusi tinggi (DEMnas) dari Badan Informasi Geospasial dan global SRTM. Tinjauan geofisika menggunakan data gravity satelit GRACE resolusi sangat tinggi diaplikasikan untuk visualisasi model bawah permukaan regional (dalam) dan model bawah permukaan residual (dangkal). Hasil visualisasi akan bermanfaat untuk studi selanjutnya dan mendukung studi tektonik regional zona subduksi Jawa.
