MODEL SISTEM PANAS BUMI BERDASARKAN DATA GRAVITY PADA DAERAH SONGA - WAYAUA, PULAU BACAN, MALUKU UTARA
Abstract
Daerah panas bumi Songa-Wayaua merupakan salah satu area panas bumi yang menarik, yang berada di Pulau Bacan, Provinsi Maluku Utara. Manifestasi panas bumi di permukaan yang terdapat di Songa-Wayaua mempunyai temperatur berkisar 65 – 103,5 C berupa mata air panas, fumarol, kolam lumpur, tanah panas dan batuan teralterasi. Survei gayaberat yang dilakukan pada tahun 2006 bertujuan untuk mengindetifikasi sistem panas bumi dan area prospeknya. Pemodelan gaya berat dengan inversi 3 dimensi menunjukkan sistem panas bumi Songa-Wayaua terkonsentrasi di bawah struktur Graben Songa, di antara Bukit Lansa dan
Bukit Pele.
