Abstract

Suoh merupakan daerah tektonik aktif yang mengakibatkan terbentuknya struktur geologi yang tersebar di Daerah Suoh. Struktur geologi yang berkembang di Daerah Suoh telah dianalisis menggunakan data gaya berat dan data DEM ALOS PALSAR untuk menentukan dan menganalisis struktur geologi serta arah dominannya. Analisis struktur bawah permukaan menggunakan metode gaya berat dengan analisis Second Vertical Derivative (SVD) dan analisis kelurusan menggunakan metode Fault Fracture Density (FFD). Kontur SVD residual bernilai 0 dan area dengan nilai FFD tinggi (2 sampai 2,6 km/km ²) mengindikasikan adanya struktur sesar dangkal. Berdasarkan analisis kelurusan data DEM telah didapatkan informasi tentang kelurusan berarah barat laut-tenggara yang sangat jelas, selaras dengan struktur geologi regional daerah Suoh.
