“…Using a geocoded single look complex (SLC) processor (Zebker, 2017; Zheng & Zebker, 2017), we processed 91 ascending (Path 78, Frames 94–104) and 82 descending (Path 85, Frames 483–493) Sentinel‐1 scenes acquired between November 2014 and January 2019 (Figure 1). We generated more than 7,000 interferograms with 120 m pixel spacing and a maximum temporal baseline of 800 days.…”

Here we used Sentinel-1 interferometric synthetic aperture radar (InSAR) data acquired between November 2014 to January 2019 to map how the basin's surface has deformed in response to fluid injection and extraction. While our stacking approach has low complexity, its accuracy increases with the Sentinel-1 data volume. With an automated outlier removal algorithm, we achieved ∼2 mm/year accuracy across the basin in the presence of up to ±15 cm tropospheric noise. We observed numerous subsidence and uplift features near active production and disposal wells, with the maximum deformation rate occurring in 2018 when production peaked. The most important deformation signatures are linear patterns that extend tens of kilometers near Pecos, TX, where a cluster of increased seismic events was cataloged by the Texas Seismological Network (TexNet). Our elastic modeling results demonstrate that fluid extraction and dip slip along normal faults are potential causes for the observed seismicity and deformation patterns. Plain Language Summary Over the past decade, breakthroughs in horizontal drilling and hydraulic fracturing have made the Permian Basin one of the most productive oil fields in the world. Using spaceborne interferometric synthetic aperture radar (InSAR), we mapped how the Permian Basin's land surface has deformed from oil and gas production activities. We developed a new processing technique to mitigate tropospheric noise associated with turbulent variations, which allows us measure ground changes with millimeter-level accuracy. We observed numerous subsidence and uplift features near active production and disposal wells. The observed deformation rate is the highest in 2018 when the largest volume of oil and gas was produced in the basin. The InSAR-observed subsidence patterns over the Pecos area can be modeled as dip slip over multiple normal faults and discretized cylindrical reservoir compaction. The implication for the scientific community, as well as a broader sector of stakeholders, is that the increase in high-quality satellite-based data now allows us to monitor vast areas for subsurface stress and pore pressure changes in oil-producing regions.

“…For the summit area, we retrieved 44 ascending (path 124, frame 55-60) and 48 descending (path 524-529, frame 76) Sentinel-1 scenes (Aug. 6, 2018-May 27, 2019 from Alaska Satellite Facility's data repository. SAR images were produced in geocoded coordinates (Zebker, 2017;Zheng & Zebker, 2017). Quality of interferograms was tested by reversing the order of re-sampling (geocoding from radar to lat-lon coordinates) and interferometry (creating interferogram and time-series), which produced < 2 mm difference in standard deviation.…”

Simultaneous summit inflation and deflation constrain the location and geometry of Halema'uma'u (HMM) and South Caldera (SC) reservoirs.• A model with time dependent magma flux between reservoirs explains the postcollapse spatial-temporal deformation pattern.• Time dependent deformations require a HMM-East Rift Zone (ERZ) pathway and a significantly less hydraulically conductive SC-ERZ pathway.

“…We used SAR data acquired between January 7, 2019 and 21 December 2019 by the Sentinel‐1A satellite, which operates at C‐band (

\sim

5.65 cm wavelength) and has a 12‐day temporal repeat in the high Arctic. We processed raw data (L1.0) collected in the interferometric wide swath mode using the “geocoded single‐look complex” (SLC) backprojection method (Zebker & Zheng, 2016; Zheng & Zebker, 2017). All SLC radar images were coregistered to a digital elevation model (DEM) spanning the region of interest and were produced from the photogrammetric ArcticDEM data set (Porter et al., 2018).…”

ICESat-2 altimetry can resolve surface subsidence that is related to changes in snowcover depth and seasonal thawing of the active layer 10 • ICESat-2 measurements of surface-height change are affected by along-track to-11 pographic gradients, and complex surface roughness 12 • Complementary ICESat-2 and InSAR datasets can be jointly leveraged for future 13 studies in periglacial environments 14
