Tracking Coastal Change in American Samoa By Mapping Local Vertical Land Motion with PS-InSAR
Characterizingdiverse contributionsto coastal land change is a key step to mitigating the effects ofrising sea levels that threaten coastal communities. This taskis particularly critical for small island communities in tectonically active regions, which are highlyvulnerableto the effects of sea level rise. We highlight here a case study to extract regional estimates of vertical land motion (VLM) over American Samoa, which in recent years has observedincreased nuisance flooding.Weusedpersistent scatterer Interferometric Synthetic Aperture Radar (PS-InSAR)to derive high-resolutionestimates of crustaldeformationinpopulated regions overTutuila Island from 2015 to 2021. While the area is small and highly vegetatedand poses challenges for InSAR, we wereable to construct a regional map of the estimated deformation ratein these areasandvalidate the time-series with alocal GPS station. Our preliminary results suggest that PS-InSAR has the ability to capture the local and regional deformation patterns, although further workis needed to compensate formore complexatmospheric effects, estimate error margins,and integrate ourresults intomodels of sea-level change that can be used local stakeholders
