Abstract

Daerah manifestasi panas bumi di kawasan Bitung telah diidentifikasi berdasarkan data anomali medan gravitasi terkoreksi hingga koreksi udara bebas yang diperoleh dari Geodetic Satellite (Geosat) dan European Remote Sensing-1 (ERS-1). Dari data ini kemudian dilakukan koreksi Bouger dan koreksi medan. Nilai anomali medan gravitasi yang dijadikan sebagai data identifikasi adalah nilai anomali gravitasi lokal yang telah dipisahkan menggunakan filter Second Vertical Derrivative (SVD). Manifestasi ditunjukkan oleh anomali tinggi dan rendah dengan nilai 6.5 mGal dan -7.5 mGal. Daerah dengan anomali tinggi dan rendah diduga sebagai daerah panas bumi di kawasan Bitung.

 

 

Kata Kunci : anomali gravitasi, panas bumi, data satelit, Bitung, koreksi Bouger.
