The geomorphic history of coastal plains can be shown through their formation and unique subsurface layering, which can indicate natural disaster occurrences and lasting environmental impacts. Determined to connect ground penetrating radar (GPR) reflections throughout the Filipino Gamay coastal plain sequence, (GPR) data were collected using Sensors and Software pulseEKKO Pro® with 100 MHz antennae at two coastal sites. For data collection, the antennae separation was one meter, and the step size was a quarter meter. The project scope is limited to the second coastal site to reveal the scale of Gamay’s coastal events, with the second site situated a kilometer northeast of the first site. Four GPR profiles were collected along three transects perpendicular to the modern coastline and one transect parallel to the coastline, linking the other three transects. Low-frequency noise was removed from all profiles with the dewow process. Radar facies with similar electromagnetic characteristics were then identified and used for interpretation. Profiles at the second site correlated to the subsurface activity experienced at the first, effectively connecting GPR reflections throughout Gamay Bay. High-energy events observed at the first site were detected a kilometer away, indicating a continuation of each event along the shoreline.
