We use interferometric synthetic aperture radar (InSAR), body wave seismology, satellite imagery, and field observations to constrain the fault parameters of M w 7.1 2011 Van (Eastern Turkey) reverse‐slip earthquake, in Turkish‐Iranian plateau. Distributed slip models from elastic dislocation modeling InSAR surface displacements ENVISAT COSMO‐SkyMed interferograms indicate up 9 m reverse oblique on a pair en echelon NW 40 °–54 ° dipping planes which have extensions projecting just 10 km...

[1] The North Anatolian Fault (NAF) is a major feature of Middle Eastern tectonics, and several previous InSAR studies have measured interseismic deformation across the fault. All studies, however, used SAR data acquired from single line-of-sight (LOS) direction, leading to large uncertainties on model parameters necessitating modelling assumptions be made. We NAF using both ascending descending for first time, an aim that has previously been limited by availability data. By two look...

Abstract Landslides are widespread geomorphological features on the North Island of New Zealand, where they represent one primary landscape-forming processes. This study focuses steepland terrain surrounding Gisborne, a city located east coast Island, at Hikurangi subduction margin. consists young, weak, sedimentary rocks and soils; most common modes slope failures soil creep, slides flows in shallow, clay-rich regolith, triggered by heavy rainfall. Based observational data from Sentinel-1...

The Lee Tunnel was constructed as the first part of Thames Tideway Improvement scheme, between 2010 and 2016. With tunnelling for East section main Tunnel, which joins at Abbey Mills Pumping Station, beginning in early 2020, this paper investigates patterns deformation London during construction Tunnel. An unexpected geological feature, later identified a drift filled hollow, discovered tunnelling. This study demonstrates that had eight years ERS Persistent Scatterer Interferometry (PSI)...

Abstract The East Coast region of New Zealand has some the highest erosion rates in world, due to its proximity an active plate boundary, susceptibility high-intensity storms and steep terrain underlain by young soft sedimentary rock soil. In city Gisborne, expansion residential blocks into steeper peri-urban areas required improved capacity for characterisation monitoring slope stability. Landslides have affected several properties destroyed infrastructure. Slope failure commonly occurs...

Tailings storage facilities (TSFs) are an essential infrastructure of mineral processing, but they represent a significant physical, chemical and biological hazard must, therefore, be strictly responsibly sited, managed closed.Tailings can, for example, dispersed by many processes (such as sinkholes, earthquakes, intense rainfall flood events, wind), substandard design construction, seepage.The stability behaviour TSFs needs to continuously monitored one highly effective way doing this is...

Propagation delay due to variable tropospheric water vapor (WV) is one of the most intractable problems for radar interferometry, particularly over mountains. The WV field can be simulated by an atmospheric model, and difference between two fields used correct interferogram. Here, we report our use U.K. Met Office Unified Model in a nested mode produce high-resolution forecast 3-km-high Mount Etna volcano. precipitable-water validated against that retrieved from Medium-Resolution Imaging...

As a result of collaboration between the Coal Authority, NPA Satellite Mapping and British Geological Survey, measurements surface deformation have been analysed across number current former UK mining areas. The work included wide-area ground stability dataset produced using interferometric synthetic aperture radar (InSAR), with associated geological interpretation, to help Authority manage these areas. Results show an unexpected amount wide areas country In particular, many are...

Several concepts have now been published for geosynchronous synthetic aperture radar (GEO SAR). The long distance means that to achieve a satisfactory signal noise ratio, the integration time may be minutes or hours. Over this period atmosphere cannot assumed static and phase compensation atmospheric perturbations is needed. A simulator has developed quantify performance of candidate schemes thus evaluate conditions in which GEO SAR imaging expected feasible. process design system (low...

Artificially introduced persistent scatterers (PS) are often desirable, and sometimes even crucial, when monitoring deformation using InSAR especially in non-urbanised areas. The use of active radar transponders as viable `artificial PS' is demonstrated via two field experiments: a validation test controlled calibration environment, their operational for landslides. In the latter case, added value having collocated InSAR-GNSS measurements also presented.

Slope instabilities can be highly disruptive, leading to damage infrastructure, halting of mine operations, and, in the worst cases, loss life.Slope range severity from slow-moving landslides (moving at millimetres per year) catastrophic mass failure events many metres second and involving tens millions cubic material).Timely identification early stages slope instability, whether an artificial or a natural slope, is essential properly mitigate impacts such hazards.Here we demonstrate how...
