ANALISIS PERGESERAN DAN REGANGAN SELAT SUNDA BERDASARKAN DATA CORS BIG TAHUN2017-2019

Abstract

Selat Sunda merupakan wilayah perairan yang berada pada pertemuan dua lempeng tektonik, yaitu lempeng Benua Eurasia dan lempeng Samudera Indo-Australia pertemuan lempeng tersebut membentuk zona subduksi sehingga menyebabkan patahan yang bergerak dan dikenal dengan Sesar Sumatra. Selain Sesar Sumatera di Selat Sunda juga terdapat aktivitas vulkanik yang disebabkan oleh aktivitas Gunung Anak Krakatau. Hal tersebut menyebabkan tingginya aktifitas geodinamika dan potensi bencana di Selat Sunda, mengingat wilayah selat sunda dikelilingi oleh provinsi yang padat penduduk dan menjadi jalur tranfortasi laut sehingga jika terjadi bencana maka banyak kerugian yang ditimbulkan. Oleh karena itu perlu adanya mitigasi bencana.Untuk mendukung mitigasi bencana maka dapat dilakuakan pemantauan pergeseran dan regangan Selat Sunda. Penelitian ini bertujuan menghitung besar pergeseran, kecepatan dan regangan Selat Sunda. Data yang digunakan yaitu data episodik titik CORS CGON, CLGI, CPSR, CSBK, CTCN dan CUJK, yang diikatkan ke 14 stasiun IGS BAKO, COCO, NTUS, XMIS, YAR3, DARW, KAT1, LHAZ, POHN, HYDE, DGAR,CUSV, SGOC, IISC, KARR dan pengolahan menggunakan software Gamit/GLOBK 10.7. Hasil penelitian ini yaitu, pergeseran horizontal titik pengamatan sebesar 34,2 – 0,0525 mm dan pergeseran ketinggian sebesar 10,9 mm s.d -45,3 mm. Kecepatan pergeseran horizontal titik pengamatan sebesar 15,832 - 25,875 mm/, titik pengamatan dominan bergerak ke arah tenggara dengan arah pergeseran sebesar 78,3260- 135,5190. Pola regangan titik pengamatan yaitu, kompresi dengan nilai kompresi -0,4254 μstrain s.d -0.2382 μstrain. Kata Kunci:KecepatanPergeseran, Pergeseran, Regangan, Selat Sunda.
