Iodination in Valencia is the worst tragedy in recent history with the terrible death toll of over 200 people and almost 1,000 still missing. Yesterday Barcelona has been hit by torrential rain and consequent flooding. https://lnkd.in/e76E9k6k

The floods ravaging Spain are considered to be the worst natural catastrohe in recent history. The floods do not ebb today, the rescure efforts are underway including ESA’s Copernicus Emergency Rapid Mapping Service. #geohazards #spainfloods #floods #earthobservation #satellitedata #esa #copernicus #satellites

Heavy rainfalls, typical for the season but unprecedented in intensity, caused devastating floods in southern Spain today, with death toll close to 100 people. Shocking aftermath. Heartbreaking.

Impressive job within #MOSMIN project's scope performed by our colleagues from #CTTC. 20 corner reflectors have been installed to verify and improve InSAR monitoring of a tailing dam at one of the mining sites in Zambia. Beautiful views from the top of the dam come as bonus.

GeoKinesia performs deformation monitoring using a proprietary Persistent Scatterer Interferometry (PSI) InSAR processing technique. The company works continuously to improve its deformation monitoring capabilities. This Newsletter concerns a recent improvement of the processing robustness, coverage and density of the deformation measurements. One of the key PSI processing steps involves the estimation of deformation velocity (DV) and the so-called residual topographic error (RTE). This is obtained by processing wrapped interferometric phases. A recent improvement of this step has been achieved by analyzing the residuals of the observation equations, i.e. the differences between the observed wrapped phases and the modeled ones, which depend on DV and RTE. By properly treating such residuals, we obtain a substantial improvement in the goodness of fit (gamma) of the original observation and the estimated linear model, which is function of DV and RTE. The figure below shows an example of gamma distribution before the above treatment (original) and after such a treatment (optimized): one may notice a substantial improvement.

Milton has hit and crossed Florida last week, losing some of its power and re-classified as category 3 storm and yet brining extraordinary distraction. NASA's animation shows its trajectory. #geohazards #earthobservation #remotesensing #satellitemonitoring #nasa #esa #hurricanes #milton #insar #geokinesia

InSAR has become de facto a standard of the geotechnical monitoring in the mining industry but its usage for geotechnical site investigation and analysis remains limited. In our next Newsletter we discuss the role InSAR could play in the geotechnical investigations and the ways the make it a standard. #insar #satellites #earthobservation #geotechnicalinvestigation #geotechnics #remotesensing #geokinesia #geotechnicalmonitoring https://lnkd.in/eNr7EY6r

Hurricane Milton will make the landfall in Florida today and may become one of the most disastrous hurricanes on record. Over 5 million people have been already evacuated, areas have prepared for the impact. #geohazards #hurricanes #landslides #earthobservation #remotesensing #satellites #satellitedata #insar https://lnkd.in/eSMsij6

NASA is publishing satellite images of the hurricane Helen aftermath, including the pictures of massive light outage in Georgia. #geohazards #earthobservations #satellites #satelliteimages #nasa #hurricanehelen #geokinesia https://lnkd.in/eEQ3heXK https://lnkd.in/eAHNQ4gw
