Abstract The launches of the Sentinel‐1 synthetic aperture radar satellites in 2014 and 2016 started a new era high‐resolution velocity strain rate mapping for continents. However, multiple challenges exist tying independently processed data sets to common reference frame producing fields. We analyze acquired between 2019 over northeast Tibetan Plateau, develop methods derive east vertical velocities with ∼100 m resolution ∼1 mm/yr accuracy across an area 440,000 km 2 . By implementing...

The DEM-generation technology from high-resolution satellite imagery enables us to generate a wide range of topographic data rapidly, improving the efficiency acquisition greatly. This method is more efficient than airborne Light Detection And Ranging (LiDAR) in terrain reconstruction, since covers larger area without difficulties field deployment. Previous researches evaluated accuracy DEMs generated stereo different sensors, however there not enough quantitative analysis concerning...

Abstract In the continents, importance of earthquakes that occur away from major block‐bounding faults is still debated. The 21 May 2021 M W ∼ 7.4 Maduo earthquake occurred on a secondary fault previously‐identified block boundaries. Here we use 7 years Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (between October 2014 and November 2021) to determine distribution coseismic slip early postseismic afterslip following earthquake, preceding interseismic strain...

The ongoing energy crisis has underscored the urgent need for energy-efficient materials with high utilization efficiency, prompting a surge in research into organic compounds due to their environmental compatibility, cost-effective processing, and versatile modifiability. To address experimental costs time-consuming nature of traditional trial-and-error methods discovery highly functional compounds, we apply 3D transformer-based molecular representation learning algorithm construct...

The development of geodetic tools, such as Interferometric Synthetic Aperture Radar (InSAR), has revolutionized our exploration earthquake physics and the assessment seismic hazard. Over past 20 years, InSAR been increasingly used to determine interseismic strain rate across major seismogenic faults. Strain derived from geodetically mapped crustal deformation rates serves an indicator a fault’s potential, in alignment with classical elastic rebound theory. However, observation...

The standard approach requires modeling velocities and relative (micro‐)plate motions, which is challenging for fault‐based We present a new to directly invert strain solve distributed simultaneously. generate velocity rate fields over the southeastern Tibetan Plateau, utilizing Sentinel‐1 Interferometric Synthetic Aperture Radar spanning 2014–2023. derive using block by inverting rates....

Postseismic deformation occurs due to stress relaxation following large earthquakes and has been widely captured by space geodetic observations. For some earthquakes, afterslip inferred take place in the fault barriers surrounding areas of coseismic asperities. This phenomenon can be explained velocity-strengthening frictional behavior prevalent velocity-weakening properties However, for events, seems exhibit spatial overlap with coseimsic slip. Here we used postseismic Maduo earthquake...

Earthquakes release strain energy that has accumulated between seismic events. Measuring accumulation rates is critical for understanding earthquake cycle and assessing potential, with fault slip serving as essential inputs hazard models. However, the Tibetan Plateau been lacking comprehensive estimates of geologic on numerous faults. To address this gap, geodetic data have invoked to derive (or deficit) using various methodologies. These include commonly adopted classic deformable block...

On February 6, 2023, two devastating earthquakes, Mw7.8 and Mw7.5, struck the area surrounding Kahramanmaraş, Türkiye, resulting in extensive complex surface deformations. The event created a rupture over 310 km along East Anatolian Fault, while Mw7.5 earthquake resulted 150 Çardak-Sürgü Fault segment. Here we use Sentinel-1 Burst Overlap Interferometry (BOI) to improve 3D displacement mapping particular investigate near-fault deformation.In...

The India-Eurasia collision zone is the largest deforming region on planet with numerous faults and widespread earthquakes, extending from Himalayan Front to north of Tien Shan. Developed plate tectonic theory, block models have long been used describe crustal deformation in zone, GPS data are often invoked constrain test models.

On 6th February, a pair of significant earthquakes with magnitudes 7.8 and 7.6 struck Kahramanmaraş, Turkey. The Earthquake InSAR Data Provider (EIDP) promptly produced interferograms offset tracking results within 3 hours acquiring Sentinel-1 satellite data. However, it was challenging to unwrap the correctly due high displacement gradient near rupture. Hence, early fields were derived from Pixel Offset Tracking (POT) method both in range azimuth direction low resolution depending on pixel...
