Abstract
Telah dilakukan penelitian mengenai relokasi hiposenter
gempa bumi menggunakan metode coupled velocityhypocenter
dan metode local earthquake tomography.
Lokasi penelitian berada di daerah sekitar Sesar Palu Koro,
Sulawesi. Dalam metode coupled velocity-hypocenter ini
menggunakan prinsip metode Geiger dan didapatkan lokasi
baru hiposenter gempa bumi, model kecepatan baru,
dan koreksi stasiun dari daerah penelitian. Sedangkan
dari metode local earthquake tomography akan
didapatkan rekonstruksi struktur bawah permukaan
bumi dengan menggunakan waveform dan travel time
dari gelombang gempa bumi. Hasil yang didapatkan
menggunakan metode coupled velocity-hypocenter
adalah terjadi liniasi yang lebih baik dan sumber gempa
bumi terkelompok. Sedangkan hasil yang didapatkan
dari metode local earthquake tomography adalah
distribusi hiposenter gempa bumi secara umum terdapat
pada kedalaman 20 kilometer hingga 40 kilometer.
=====================================================================================================
Research has been performed about hypocenter relocation of
earthquakes using coupled velocity-hypocenter method and
local earthquake tomography method. The location of
research is in the area around Palu Koro Fault, Sulawesi.
Coupled velocity-hypocenter method using the principle of
Geiger method and get the new location of earthquake
hypocenter, the new velocity model, and correction stations
of regional research. Whereas local earthquake tomography
method will get reconstruction of subsurface structure by
using waveform and travel time of seismic waves. Results
obtained from velocity-coupled hypocenter method is have a
better continuity of earthquake event and the earthquakes are
clustered. Whereas the results obtained from local
earthquake tomography method is the distribution of
earthquake hypocenter in general are at a depth of 20
kilometers to 40 kilometers.
