Gunung Bombalai adalah gunung kerucut piroklastik di Divisi Tawau, Sabah, Malaysia.^[1] Ketinggiannya Mencapai sekitar 531 meter.^[2]

Geologi

Gunung ini merupakan bagian dari medan vulkanik Tawau yang berkontribusi terhadap ciri topografi yang menonjol di Semenanjung Semporna di timur laut Kalimantan dan sisi barat lembah di bagian tengahnya.^[3]^[4]^[5] Kerucut vulkanik rendah berada di utara Pulau Sebatik dan memiliki kawah selebar sekitar 300 m di selatan. Dua aliran lava muda memanjang hampir sampai ke dataran pantai. Aliran tersebut dianggap lebih muda dari aliran radiokarbon lava yang berumur sekitar 27.000 tahun sebelum sekarang, dan ekstrusi lava basaltik kemungkinan berlanjut hingga zaman Holosen.^[6] Kehadiran aktivitas energi panas bumi telah dilaporkan di pegunungan sekitarnya.^[7]^[8]

In Sabah, Tawau's Bombalai volcano is currently a dormant volcano and, since it estimated to have erupted thousands of years ago, it can be regarded as an ancient crater. Bombalai cinder cone is only a half-an-hour jungle walk from the entrance of Tawau Hills National Park.
