Bathymetry Changed Mapping in Pagai Island Using Remote Sensing

Abstract Pagai Island is part of the Mentawai Islands and is located in the collision

area of two large plates, namely the Indo-Australian and Eurasian plates, causing high tectonic activity. One of the consequences of the movement of these plates is a change in the shape of bathymetry. However, bathymetric changes have not been well-mapped. To map tectonic plate movement-related changes in the sea floor, we use Sentinel-2 satellite images and a remote sensing technique. These changes show where earthquakes might happen. In conclusion, significant bathymetric changes occurred west of Pagai Island. The changes that occurred took the form of increasing depth in the waters.
