Meliza Anggraeni, - (2018) RELOKASI HIPOSENTER GEMPABUMI DENGAN MENGGUNAKAN METODE DOUBLE DIFFERENCE (STUDI KASUS: ZONA BUSUR BANDA PADA TAHUN 2010 – 2017). S1 thesis, Universitas Pendidikan Indonesia.
Abstract
Zona Busur Banda merupakan salah satu wilayah yang tingkat
seismisitasnya sangat tinggi serta rawan terhadap bencana gempabumi
karena adanya penunjaman lempeng Indo-Australia terhadap lempeng
Eurasia di sepanjang pelengkungan Busur Banda, tercatat selama 8
tahun terakhir ini sudah terjadi gempabumi sebanyak 4518 kali. Data
katalog yang presisi sangat dibutuhkan sebagai data referensi untuk studi
tektonik dan studi kegempaan. Karena informasi mengenai hiposenter
yang akurat sangat penting, maka untuk menghasilkan hiposenter yang
lebih akurat dilakukan relokasi hiposenter gempabumi dengan
menggunakan metode Double Difference (DD). Metode Double
Difference (DD) adalah suatu metode relokasi hiposenter yang
menggunakan data arrival time gelombang P dan S. Pada dasarnya
prinsip dari metode ini adalah mengasumsikan jika jarak persebaran
hiposenter antara dua gempabumi sangat kecil dibandingkan dengan
jarak antara stasiun dengan sumber gempabumi, maka raypath kedua
gempabumi tersebut dapat dianggap sama. 1210 event gempabumi
berhasil direlokasi dengan nilai resudual waktu tempuh yang mendekati
nol. Hasil ini menunjukkan bahwa relokasi hiposenter menggunakan
metode Double Difference dengan bantuan program hypoDD relatif
akurat untuk digunakan merelokasi gempabumi Zona Busur Banda pada
tahun 2010-2017, serta membuktikan bahwa wilayah Busur Banda
membentuk seperti sendok terbuka berdasarkan hasil geometri slab-nya.
;---The Banda Arc is a territory with a very high level of seismicity
and vulnerable to earthquake, because of the collision of Indo-Australia
plate against the Eurasian plate along the curvature of the Banda Arc. It
is recorded that 4518 earthquakes has occoured in the past 8 years. A
precise catalog data is urgently needed as a reference data for tectonics
and seismicity studies. For the need of accurate information of
hypocenter, earthquake hypocenter relocation using the Double-
Difference (DD) method was done to obtain more precise information of
hypocenter. Double-Difference (DD) is a hypocenter relocation method
using arrival time data of P and S waves. This method assumes that if
the distance of hypocenter distribution between two earthquakes is very
small compared to the distance between stations and earthquake source,
then the raypath of those earthquakes can be considered the same. 1210
earthquakes are successfully relocated with the residual value of travel
time approaching zero. These results indicate that the relocation of
hypocenter using Double Difference method with the help of hypoDD
program is relatively accurate for relocating earthquake on Banda Arc
Zone in 2010-2017, as well as proving that the area of Banda Arc
formed as an opened spoon based on its slab geometry. The residual
value of travel time approaching zero are expected to provide more
precise information of hypocenter position to government agencies and
society as disaster mitigation in earthquake vulnerability mapping in
order to minimize the damage of earthquake.
