Abstract

Telah dilakukan perhitungan beberapa nilai percepatan tanah kota Padang akibat gempa bumi dari Segmen Mentawai dari beberapa persamaan empiris yang divalidasi   dengan data percepatan tanah dari akselerograf yang terpasang di Stasiun Maritim Teluk Bayur Padang. Data gempa yang digunakan adalah data gempa dari  Segmen Mentawai dari tahun 2013 – 2017 yang terekam di akselerograf  Stasiun Maritim Telukbayur Padang. Digunakan 4 rumusan empiris, yaitu Mc.Guire, Fukushima-Tanaka, Esteva, dan Donovan. Hasil validasi menunjukkan bahwa rumusan Fukushima-Tanaka merupakan rumusan paling cocok  digunakan untuk Kota Padang dengan persentase kesalahan rata-rata terendah sebesar 51%, sedangkan 3 rumusan lainnya mempunyai persentase kesalahan rata-rata yaitu Mc.Guire 396%, Esteva 74%, dan Donovan 861%.
