Abstract

Akibat tumbukan antara lempeng Indo-Australia dan Eurasia dimana lempeng Indo-Australia menunjam di bawah Sumatera, wilayah Sumatera Barat sebagaimana wilayah lain di depan muka busur (fore-arc) Sunda memiliki potensi gempa besar. Di wilayah muka busur diketahui ada dua potensi gempa besar dengan siklus 200 sampai 250 tahun, yakni segmen Siberut dan segmen Sipora-Pagai (Hilman, 2005) yang merupakan megathrust. Gempa besar di kedua segmen ini berpotensi tsunami. Menurut Hamzah Latif (2005) kalau tsunami terjadi, ia akan sampai di pesisir barat Sumatera Barat dalam waktu antara 30 menit sampai sejam sesudah gempa besar terjadi. Berbagai isu sempat berkembang yang menyebutkan bahwa tsunami bisa sampai ke Padang dan wilayah lain di pesisir barat Sumatera Barat dengan waktu lebih singkat. Analisis berikut memperkuat penelitian yang sudah dihasilkan oleh Hamzah Latif serta juga Subandono.
