“…Namun secara empiris PGA dapat dihitung dengan rumusan konversi parameter gempa bumi yang disebut Ground Motion Prediction Equation (GMPE). Dalam penelitian ini PGA didapatkan secara empiris menggunakan GMPE yang dikembangkan oleh Octhav dkk, dimana persamaan ini merupakan pengembangan dari GMPE yang di usulkan oleh Zhao et al [5], [6] Nilai PGA dihitung menggunakan persamaan(1). Nilai tersebut dihitung di setiap titik grid di daerah studi dengan jarak antar titik 1 km.…”

Telah dilakukan pemetaan bahaya gempa bumi di Maluku Utara menggunakan skenario gempa bumi Halmahera 11 September 2008 dengan magnitudo 7,6. Analisis menggunakan metode deterministik dengan fungsi atenuasi Zao et al modifikasi untuk wilayah Sulawesi. Parameter yang digunakan dalam perhitungan yaitu magnitudo, kedalaman gempa bumi, jarak pusat gempa ke lokasi penelitian, mekanisme sumber, dan Vs30. Diperoleh hasil berupa sebaran PGA dan Intensitas gempa bumi di Maluku Utara berkisar antara 0,006g hingga 1,85g, dengan intensitas gempa bumi berkisar antara III MMI hingga VIII MMI. Nilai PGA dan intensitas gempa bumi terbesar berada pada wilayah Halmahera Barat dan Halmahera Utara, dimana wilayah ini berdekatan dengan sumber gempa.

In the 1990s there were 7 (seven) deadly tsunami events due to earthquakes in Indonesia. There is M 7.8 North-east of Flores island sea earthquake (1992), M 7.6 South of Java island sea earthquake (1994), M 6.8 South of Timor Island sea earthquake (1995), M 7.8 North-west of Sulawesi island sea earthquake (1996), M 7.9 East of Biak island sea earthquake (1996), M 7.7 Taliabu island sea earthquake (1998), and M 7.4 East of Banggai Island sea earthquake (2000). Those earthquake and tsunami disasters events affected the number of casualties and damaged houses in coastal areas. Surely those events present a few lessons learned for future disaster preparedness in Indonesia.

This study aims to denote the possible casualties and damages due to the M<5 earthquake. We used the desk study of literatures to explore earthquake disaster reports. The published significant and destructive earthquakes catalogue by BMKG Indonesia along 2015-2019 noted that six events out of them in Java island due to by below magnitude 5 (M<5) earthquakes. Those are sourced in the land and shallow depth focus on the active faults region. Those earthquakes also cause human losses, that is three events out of them induce casualties, and kill two (2) people. Preliminary analysis concludes that the short distance to earthquake source and local site condition was responsible for this unexpected building damages. We suggest this events to be the lesson learned for disaster risk managers to consider the low magnitude earthquake also able to generate the high hazard on the certain seismic prone areas.
