Analisis Bahaya Kegempaan Di Wilayah Provinsi Sulawesi Utara
Keywords:
psha, pga, fault, subduksi, backgroundAbstract
Pada penelitian ini digunakan model probabilistic seismic hazard analysis (PSHA) untuk mengambarakan kontribusi peak ground acceleration (PGA) di wilayah Provinsi Sulawesi Utara. Sumber gempa subduksi, fault dan background diterapakan dalam perhitungan PSHA. Adapaun Model gridded seismicity diterpakan untuk mengakarkterisasi model background source berdasarakan seismicity rate pada setip grid berukuran 10 x 10 derajat. Hasil yang diperoleh adalah kontribusi PGA di di Provinsi Sulawesi Utara untuk probabilitas terlewati 10% dalam 50 tahun pada kondisi T = 0 detik sebesar 0.5 g - 0.7, T = 0.2 detik sebesar 1.4 g - 1.5 g dan T = 1 detik sebesar 0.6 g - 0.7 g.
