\begin{abstract}
The Coast of Louisiana is affected by accelerating sea level rise
compounded by land subsidence, leading to land loss. Vertical crustal
motions in the region are caused by natural and anthropogenic processes
that vary temporally and spatially across the Gulf of Mexico. We
investigate the role of growth faulting contributions to subsidence in a
case study of Baton Rouge, where two E-W striking, down-to-the-south
normal faults, the Denham Springs and Baton Rouge faults, cut compacted
Pleistocene strata, and where sediment compaction should be minimal. We
used InSAR time series and LiDAR differencing data spanning 1999-2020 to
quantify modern vertical and horizontal displacements. After calibration
with GNSS data, both methods reveal similar spatial patterns in ground
motion, with the faults delimiting areas with different absolute rates.
On average the area north of the Baton Rouge fault is subsiding faster
than the south, opposite to the long-term sense of fault slip. LiDAR
mean vertical rates range between -5 to -11 mm/y and -2.4 to -7 mm/y.
InSAR time-series mean rates in the LOS direction range between -10.9 to
-13.6 mm/y and -8 to -10.6 mm/y, respectively, for the north and south
areas. Subsidence in the northern area likely is controlled by
groundwater level changes caused by pumping as indicated by groundwater
extraction models. The southern area average is likely influenced by the
injection of fluids. Our results suggest volumetric changes caused by
fluid extraction and injection in regions separated by growth faults
that are creeping to accommodate the spatial variations in subsidence.%
