Tsunami Numerical Simulation Applied to Tsunami Early Warning System Along Sumatra Region

Abstract: Western Sumatra region is tectonically active region that often lead to catastrophic earthquakes and tsunamis. When the tsunami disaster will occur and how big run-ups and expansion of the resulting tsunami inundation, could be the arrival time calculation and simulation, it is done by creating a scenarios tsunami modeling before the real tsunami is occured. To generate a tsunami modeling in large quantities will require a variety of mechanisms fault scenarios, subsequently scenarios variations are grouped in … Show more

“…Then we analysed and processed the earthquake parameter data to plot, and run the tsunami run-up modeling on bathymetry map cross-section along the Andaman & Nicobar ridge to the Sunda Trench of the western part of Sumatra ( Figure 5). This plot results provide information about subsurface conditions and run-up of tsunami from earthquake source to the coastline in the study area (Setyonegoro, W. 2011). Earthquake source mechanism parameters for modeling tsunami of Aceh 11 April 2012 earthquake in related with landslide explained in figure 4.…”

“…Buku tersebut disusun sebagai salah satu implemen-tasi kegiatan pelayanan publik BMKG dalam hal mitigasi bencana gempa bumi dan tsunami di Indonesia yang menjadi salah satu tanggung jawab BMGK (BMKG, 2018). Data kejadian tsunami pada buku tersebut dibagi ke dalam 6 periode waktu yaitu sebelum tahun 1600, antara 1600 -1699, 1700 -1799, 1800 -1899, 1900 -1999, dan 2000 -2017. Menurut Setyonegoro (2011), tsunami adalah kumpulan gelombang air atau ombak yang disebabkan oleh perpindahan volume air dalam skala besar misalnya yang terjadi di lautan. Kecepatan rambat gelombang tsunami sangat tergantung pada kedalaman laut.…”

“…Hasil focal mechanism tersebut juga didukung oleh penelitian sebelumnya bahwa gempa yang terjadi pada wilayah dekat zona subduksi Sumatera merupakan gempa yang menghasilkan sesar yang relatif ke arah vertikal dengan nilai kemiringan tertentu [4] . Sedangkan menurut Setyonegoro(2011) [9] , gempa menghasilkan sesar naik banyak terjadi pada kawasan zona subduksi Sumatera. [10] bahwa Sesar Mentawai merupakan sesar yang aktif ke arah mendatar (strike-slip).…”
