Penelitian mengenai identifikasi sesar di Perairan Misool dengan menggunakan metode magnetik telah dilakukan. Data yang digunakan berupa data distribusi medan magnet total. Proses penelitian ini dimulai dengan mengkoreksi data menggunakan koreksi IGRF (International Geomagnetic Reference Field) dan koreksi Tie-line Levelling untuk mendapatkan distribusi medan magnet lokal. Dari distribusi medan magnet lokal dipilih tiga buah zona anomali. Pada ketiga zona ini, dibuat sebuah sayatan 1D untuk mengidentifikasi kemungkinan keberadaan sesar dibawah permukaannya (lintasan A-A"™, B-B"™ dan C-C"™). Berdasarkan hasil pemodelan inversi pada ketiga lintasan, diketahui bahwa di bawah lintasan A-A"™ ditemukan keberadaan sesar dengan posisi yang membentang dari Barat Laut ke arah Tenggara dan berada pada kedalaman 25 hingga 75 meter dari dasar permukaan laut.
