Part 7/12:

To monitor these seismic risks, Indonesia and Singapore have installed a network of GPS stations as part of the Sumatran GPS Array (SuGAr). These stations track ground movement, offering critical insights into tectonic plate movements beneath the Earth's surface. Research focuses on the "Mentawai Seismic Gap," an unruptured segment of the faultline last active in 1797, which presents a significant tsunami threat if it ruptures.
