Kerapatan kelurusan suatu lokasi dalam geologi umumnya dikaitkan dengan daerah dengan permeabilitas batuan tinggi. Daerah dengan permeabilitas batuan tinggi dikaitkan dengan keberadaan reservoir panas bumi serta manifestasi sistem panas bumi di permukaan. Setiap sistem panas bumi memiliki model konseptual yang berbeda, sehingga tidak semua daerah dengan nilai kerapatan kelurusan tinggi dapat dikorelasikan dengan reservoir panas bumi ataupun manifestasi panas bumi. Salah satu contoh sistem panas bumi yang memiliki kasus tersebut adalah sistem panas bumi di Kotamobagu, Sulawesi Utara. Peta kerapatan kelurusan daerah Kotamobagu menunjukan bahwa manifestasi panas bumi tetap muncul bahkan di daerah dengan nilai kerapatan kelurusan yang rendah. Peta kerapatan kelurusan Kotamobagu menunjukan bahwa terdapat perbedaan pola manifestasi sistem panas bumi di Kotamobagu. Bagian timur laut Kotamobagu menunjukan manifestasi panas bumi tersebar di daerah dengan kerapatan kelurusan tinggi, sedangkan bagian barat laur Kotamobagu menunjukan manifestasi panas bumi tersebar di daerah dengan kerapatan kelurusan rendah. Perbedaan pola kemunculan manifestasi panas bumi menunjukan adanya potensi dua sistem panas bumi berbeda di Kotamobagu.
