A preliminary investigation of Holocene neotectonics of Northwest Luzon, Philippines based on uplifted coral terraces and dunes

This pilot project presents the initial phase of a potential long-term project to investigate the nature and timing of Holocene uplift events in Northwest Luzon, Philippines. Such a record will help in characterising the nature and periodicity of large seismic events on the subduction megathrust under the central part of the Manila Trench. The initial survey will apply a combination of geophysical subsurface investigation (GPR) and topographic survey techniques to investigate the subsurface structure of Paoay Dune field and Badoc uplifted reef platforms with a view to target areas for further investigation, including coring and a dating programme employing OSL, 14C and U/Th techniques.
