Irawan, DahliaKurniawati (2013) Penentuan Pusat Aktivitas Hidrotermal Daerah Cangar, Jawa Timur, Berdasarkan Analisis Pergerakan Partikel (Particle Motion). Sarjana thesis, Universitas Brawijaya.
Abstract
Telah dilakukan penelitian panasbumi di daerah Cangar, Jawa Timur, menggunakan analisis pergerakan partikel gempa. Analisis pergerakan partikel terdiri dari komponen horisontal untuk menentukan episenter dan komponen vertikal untuk menentukan hiposenternya. Penentuan episenter dan hiposenter berdasarkan arah pergerakan partikel menggunakan metode satu stasiun, yaitu stasiun perekaman CGR01 dan CGR02 yang masing-masing dipilih 5 event . Hasil dari analisis pergerakan partikel diperoleh 5 episenter gempa mikro berdasarkan pertemuan arah pergerakan partikel dua titik stasiun perekaman. Sebaran episenter berada di 5 titik, yaitu (112°32’2,04” BT; 7°44’32,208” LS), (112°32’2,04” BT; 7°44’32,1” LS), (112°32’0,96” BT; 7°44’31,49” LS), (112°32’3,57” BT; 7°44’32,58” LS), dan (112°32’3,44” BT; 7°44’32,67” LS). Sedangkan kedalaman sumber gempa berada pada 17 hingga 60 meter di bawah permukaan bumi. Titik episenter dan hiposenter berkaitan dengan adanya aktivitas hidrotermal di bawah permukaan bumi.
English Abstract
Research on geothermal has been conducted in Cangar area, East Java, using particle motion analysis. Particle motion analysis consists of horizontal component to determine epicenter and vertical component to determine hypocenter. Determination of epicenter and hypocenter are based on direction of particle motion using singlestation methods. On each station CGR01 and CGR02 three events are chosen. Results of particle motion analysis, five epicenters obtained, based on intersection of particle motion direction on both station. There are (112°32’2,04” BT; 7°44’32,208” LS), (112°32’2,04” BT; 7°44’32,1” LS), (112°32’0,96” BT; 7°44’31,49” LS), (112°32’3,57” BT; 7°44’32,58” LS), dan (112°32’3,44” BT; 7°44’32,67” LS). Whereas the hypocenter of earthquake ranging from 30 – 60 meters from surface. The epicenter and hypocenter related with hydrothermal activity in subsurface. Keywords: particle motion analysis, hydrothermal, Cangar
