Tangkuban Perahu volcano located in West Java is one of the active volcanoes in Indonesia. Due to its activity that is quite recent in geological terms dan its close proximity to the two big cities, Bandung (20 km south of the volcano) one of the most densely populated and Subang (27 km north of the volcano), it makes crucial reason to study its eruptive history in order to forecast the volcani…
The first detailed tephra statigraphy in order to elucidate the eruptive history of Tangkuban Perahu volcano, West Java, Indonesia is presented as fuller detail as possible. It contains detailed description of outcrops, correlation of reference sections, radiocarbon dating combined with K-Ar data, rigorous measurement of thickness, density, vesicularity, and grain size analyses.
Tangkubanparahu merupakan gunungapi aktif yang sering mengalami peningkatan kegiatan, untuk itu dilakukan pemantauan kegempaan secara terus menerus. Dalam penelitian ini dilakukan analisis fisis terhadap hasil estimasi frekwensi gempa, magnitudo lokal (M1), energi gempa (E), hubungan magnitudo lokal-frekuensi gempa (harga b), hiposenter, mekanisme fokus dan curah hujan. Magnitudo lokas dihitu…
