**Part 4 of a series on tracking landscape changes in Bangladesh. Read [part 1](link), [part 2](link), and [part 3](link) here.**
After completing the servicing and repair of instruments in the coastal zone to monitor land subsidence and sedimentation, my fieldwork now shifts focus to the GNSS instruments in eastern Bangladesh for studying tectonics and earthquake hazards.
Upon returning to Dhaka, Austin departed for home, and soon after, Lin Shen, my postdoc, and Ken Austin, a geodetic engineer, arrived. Lin is utilizing satellite radar data to visualize land deformation in the IndoBurma subduction zone. This expedition allows her a close-up encounter with the area she studies in depth. Ken, from the EarthScope Consortium, previously UNAVCO, funded by the NSF for geodetic research, has been instrumental in getting the GNSS receivers in the south back online.
Our team at the Dhaka University Geology Department, established the same year as Lamont, is a blend of expertise and experience. The group consists of Sanju, Lin, Ken, myself, and Babu.
After spending a few days in Dhaka for meetings, we met Sanju Singha, responsible for maintaining the instruments at Dhaka University, to collect all the necessary equipment for the fieldwork. Sanju will join us shortly after finishing some job-related exams.
Heading east across the Meghna River to Comilla, near the Indian border, we made a stop at the Mainamati archaeological site, showcasing the ruins of a 1,200-year-old Buddhist monastery. The historical location drew large crowds, and while there, we were greeted with curiosity and requests for photos. Following this visit, we proceeded to our hotel, skipping dinner after a late lunch.
