Results: Nine-Year L-band InSAR Time Series of Tectonic and Non-tectonic Surface Deformation in Northern California This repository provides geocoded Line-of-Sight (LOS) deformation products for three ALOS-2 ScanSAR tracks spanning northern California (2015–2024), as well as higher-resolution subsets used in the case study figures and final 3D velocity fields. Files follow MintPy HDF5 conventions. Regional Products (NC_ALOS2_10_56_CASR_results.zip 10/56 looks): corrected velocity fields, per-pixel geometry, displacement time series, and GNSS velocities. Case Study Products (NC_ALOS2_5_28_T170_results.zip 5/28 looks): corrected velocity fields, per-pixel geometry, and displacement time series. 3D Products (NC_ALOS2_068_170_CASR_3D_results.zip 10/56 looks): velocity fields from semi-up, insar-only, and insar-gps realizations. Supplement files for figures (figure_inputs.zip): shapefiles/CSVs for map reproduction (fault traces, canal centerlines, frame bounds etc). Open Research and Software Original ALOS-2 ScanSAR Level 1.0 SLC products are publicly available and can be searched and downloaded via JAXA's G-Portal . Many of the ALOS-2 ScanSAR products used here are now available from the NASA Alaska Satellite Facility data archive. The SAR processing is performed using the ISCE-2 software (isce2=2.6.1=py38h254090d_4) with the post-processing recipes available on github. Sentinel-1 products are publicly available from ASF and were processed using the Hybrid Pluggable Processing Pipeline (HyP3)—a cloud-based infrastructure for standardized SAR data processing—provided by ASF.

Danielle Lindsay has been supported by the Future Investigators in NASA Earth and Space Science and Technology (FINESST) and Fulbright-EQC awards. Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration (80NM0018D0004) and supported by the Earth Surface and Interior focus area. The original ALOS-2/PALSAR-2 Data Products for the period 2015 - 2021 were provided by projects RA4-PI Project 1298 and RA6-PI Project 3311. ALOS-2/PALSAR-2 Data Products from July 2021-present were provided by ©JAXA 2025 as part of a NASA-JAXA imagery agreement, data management, and storage facilitated by ASF. Archiving support of raw ScanSAR products was provided by the Western North America InSAR (WInSAR) Consortium, and archiving of final results was provided by EarthScope, with assistance from Kang Wang. This research used the Savio computational cluster resource provided by the Berkeley Research Computing program at the University of California, Berkeley (supported by the UC Berkeley Chancellor, Vice Chancellor for Research, and Chief Information Officer). This work used the PyGMT library for data processing and visualization, which is built on the GMT 6 software.
