Penyebab Terjadinya Tanah Longsor

Pada prinsipnya, tanah longsor terjadi bila gaya pendorong pada lereng lebih besar daripada gaya penahan. Gaya penahan umumnya dipengaruhi oleh kekuatan batuan dan kepadatan tanah, sedangkan gaya pendorong dipengaruhi oleh besarnya sudut lereng, air, beban, serta berat jenis tanah/batuan.
