| Summary: | At present there are several methods for monitoring volcanic activity such as seismic, deformation, gas chemicals, thermal, and remote sensing. Mount Agung, which is located on the north side of Bali, has been recorded to have erupted since 1808. In 2017, the eruption occurred along with volcanic earthquakes that led to the flow of lava, clouds, rocks, and ash.
This research uses the deformation method to get the pattern velocity and deformation model on the surface of Mount Agung during the eruption in 2017 using data from five observation stations belonging to Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) - also known as the Indonesian Center for Volcanology and Geological Hazard Mitigation (CVGHM) around Mount Agung. The data obtained is a daily resolution coordinate data processing with GAMIT/GBLOK 10.6 software. The resulting coordinates are used to calculate the magnitude of the shift, the shift correlation to seismic activity, and the shift correlation before, during and after the 2017 eruption at Mount Agung.
The result explains GPS observation in Mount agung can be used to indicate deformation before volcanic activity begins. The correlation between volcanic activity and deformation can be characterized by volcanic seismicity. Deformation patterns on Mount Agung can be used to estimate magma chamber |
