By means of the permanent scatterer (PS) technique, repeated spaceborne synthetic aperture radar (SAR) images with relatively low resolution (about 25 m × 5 for European Remote Sensing (ERS) and Envisat satellites) can be used to estimate displacement (1-mm precision) 3-D location (1-m targets that show an unchanged electromagnetic signature. The main drawback PS technique is limited spatial density behave coherently during whole observation span (hundreds PSs per square kilometer in urban...
On February 6, 2023, two large earthquakes occurred near the Turkish town of Kahramanmaraş. The moment magnitude (Mw) 7.8 mainshock ruptured a 310 km-long segment left-lateral East Anatolian Fault, propagating through multiple releasing step-overs. Mw 7.6 aftershock involved nearby strike-slip faults Fault Zone, causing 150 rupture. We use remote-sensing observations to constrain spatial distribution coseismic slip for these events and 20 6.4 Antakya. Pixel tracking optical synthetic...

This article offers a comprehensive AI-centric review of deep learning in exploring landslides with remote-sensing techniques, breaking new ground beyond traditional methodologies. We categorize tasks into five key frameworks—classification, detection, segmentation, sequence, and the hybrid framework—and analyze their specific applications landslide-related tasks. Following presented frameworks, we state-or-art studies provide clear insights powerful capability models for landslide mapping,...
Epidemiological studies reported associations between ozone (O3) exposure and cardiovascular diseases, yet the biological mechanisms remain underexplored. Hypoxia is a shared pathogenesis of O3-associated diseases; therefore, we hypothesized that O3 may induce changes in hypoxia-related markers, leading to adverse effects. This study aimed investigate short-term with hypoxic biomarkers arterial stiffness. We conducted panel involving 210 young healthy residents 2 cities at different...
Sentinel-1 data has been widely employed for monitoring large-scale ground deformation with multi-temporal InSAR (MTI). The development of polarimetric MTI (PolMTI) methods made it possible to combine both VV and VH channels better data. However, traditional high-efficiency PolMTI cannot adaptively optimize persistent scatterer (PS) distributed (DS), while existing adaptive have high computational burdens. To address these challenges, we propose an coherency matrix decomposition method...
Stratospheric ozone depletion and emission of greenhouse gases lead to a trend the southern annular mode (SAM) toward its high-index polarity. The positive phase SAM is characterized by stronger than usual westerly winds that induce changes in physical carbon transport. Changes natural budget upper 100 m Southern Ocean response are explored with coupled ecosystem-general circulation model regression analysis. Previously overlooked processes important for ocean during period identified,...

The distribution of slip during an earthquake and how it propagates among faults in the subduction system play a major role seismic tsunami hazards, yet they are poorly understood because offshore observations often lacking. Here we derive rupture evolution 2016 Mw 7.9 Kaikōura (New Zealand) that reconcile surface rupture, space geodetic measurements, seismological waveform records. We use twelve fault segments, with eleven crust one on megathrust interface, to model data match features...
Abstract Extension deficit builds up over centuries at divergent plate boundaries and is recurrently removed during rifting events, accompanied by magma intrusions transient metre-scale deformation. However, information on near-field deformation has rarely been captured, hindering progress in understanding mechanisms evolution. Here we show new evidence of oblique rift opening a event influenced pre-existing fractures two extension accumulation. This originated from the Bárðarbunga caldera...
Crustal rock strength from outer space The response of crustal to stresses is challenging estimate yet vital for determining risks events such as earthquakes. Moore et al. take advantage the recent M w 7.1 Kumamoto earthquake in Japan determine rheology rocks region. observed inversion strain rates demonstrates that certain areas have stiff and others (e.g., under Aso volcanic complex) much weaker rock. results match up with expectations, which means method can successfully measure...
Nuclear testing under the radar North Korea conducted its sixth underground nuclear weapons test in September 2017. The seismic waves generated from allow for triangulation and explosive yield estimates. However, Wang et al. show that synthetic aperture (SAR) should be added to arsenal of techniques used detect characterize tests. SAR tracks deformation space, which resulted a better constraint source parameters by using subsequent collapse Mount Mantap. occurred at depth about half...
Abstract Sentinel‐1's continuous observation program over all major plate boundary regions makes it well suited for earthquake studies. However, decorrelation due to large displacement gradients and limited azimuth resolution of the Terrain Observation by Progressive Scan (TOPS) data challenge acquiring measurements in near field many ruptures prevent displacements along‐track direction. Here we propose fully exploit coherent incoherent information TOPS using standard interferometric...

InSAR phase discontinuities show that is bounded by...

Offsets of synthetic aperture radar (SAR) images have played an important role in deriving complete three-dimensional (3-D) surface displacement fields geoscientific applications. However, offset maps often suffer from multiple outliers and patch-like artifacts, because the standard offset-measurement method is a regular moving-window operation that does not consider scattering characteristics ground. Here, we show by focusing measurements on predetected strong reflectors, reliability...
