Telah dilakukan penelitian aktivitas tektonik Pulau Bali yang bertujuan untuk mengidentifikasi dan menentukan arah pergerakan deformasi pulau Bali. Penelitian dilakukan dengan menggunakan data hasil pencatatan GPS lokal di sebelas titik pengamatan di Pulau Bali. Pengolahan data dilakukan menggunakan SOFTWARE GAMIT/GLOBK 10.6 dan beberapa software pendukung seperti teqc untuk menguji kualitas data perekaman GPS dan GMT untuk memplot data hasil pengolahan. Hasil penelitian menunjukkan bahwa terjadi pergeseran titik pengamatan yang mengindikasikan adanya aktivitas tektonik di Pulau Bali. Pola pergeseran titik menunjukkan terjadinya pergeseran yang cenderung ke arah timur hingga tenggara. Pola deformasi tersebut diperkirakan terjadi akibat aktivitas lempeng tektonik yang berada di bagian timur dan selatan pulau Bali.
Research has been carried out related to subsurface structures in the Tejakula Buleleng Bali area and its surroundings using the gravity method. This study aims to identify the local Tejakula fault. The data used in this study is gravity anomaly data obtained from observations of Geodetic Satellite (GEOSAT). The method used in interpreting the type of disturbance uses the Second Vertical Derivative method, which then produces two-dimensional (2D) and three-dimensional (3D) fault model interpretations. Based on the results obtained in the study, the condition of the bouguer gravity anomaly value in the Tejakula area and its surroundings at the research location is in the range of 65 mGal to 185 mGal. Meanwhile, based on the Second Vertical Derivative method in determining the type of fault, the Tejakula Fault can be categorized as a mandatory fault with an upward trend.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
