Abstract

Telah dilakukan pemodelan tinggi dan waktu tempuh gelombang tsunami di pesisir pantai Bengkulu dengan menggunakan software L-2008 dan Travel Time Tsunami (TTT). Dalam penelitian ini digunakan data historis gempa bumi Bengkulu 4 Juni 2000 dengan skenario magnitudo 8 Mw, 8,5 Mw dan 9 Mw. Daerah dampak tsunami yang diamati adalah Muko-Muko, Ketaun, Kota Bengkulu, Mana dan Kaur. Dari hasil pemodelan diperoleh bahwa daerah yang paling cepat dihantam tsunami adalah daerah Mana dengan waktu 20 menit 7 detik. Nilai run up tsunami tertinggi juga berada di daerah Mana. Nilai run up yang diperoleh dari hasil pemodelan menggunakan skenario magnitude 8 Mw adalah 2,01 m, skenario magnitudo 8,5 Mw adalah 4,05 m dan skenario magnitudo 9 Mw adalah 9,31 m.
