In this work, we present a methodology for improving persistent scatterer interferometry (PSI) data analysis landslide studies. This is revision of previously described procedures with several improved and newly proposed aspects. To both evaluate validate the results from methodology, used various (PS) datasets different satellites (ERS – ENVISAT, Radarsat, TerraSAR-X, ALOS PALSAR) that were processed using three PSI techniques (stable point network SPN, permanent PSInSAR™, SqueeSAR™) to map...
Satellite remote sensing is a powerful tool to map flooded areas. In recent years, the availability of free satellite data significantly increased in terms type and frequency, allowing production flood maps at low cost around world. this work, we propose semi-automatic method for mapping, based only on images open-source software. The proposed methods are suitable be applied by community involved hazard management, not necessarily experts processing. As case studies, selected three events...
Results of a PSInSAR™ project carried out by the Regional Agency for Environmental Protection (ARPA) in Piemonte Region (Northern Italy) are presented and discussed. A methodology is proposed interpretation PSInSARTM data at regional scale, easy to use public administrations civil protection authorities. Potential limitations technique ground movement detection on scale monitoring then estimated relationship with different geological processes various environments.
Abstract The kinematic acceleration of rock glaciers observed in recent decades shows that the behavior these landforms is related to climate change. Velocity variations on yearly seasonal time scales are frequently investigated, but velocity changes measured shorter (i.e., hourly resolutions) as yet poorly investigated. We used a ground based synthetic aperture radar investigate, an scale, displacement glacier located Val Senales (European Alps, northern Italy). fluctuations occurring at...
Satellite remote sensing is a powerful tool to map flooded areas. In the last years, availability of free satellite data sensibly increased in terms type and frequency, allowing producing flood maps at low cost around World. this work, we propose semi-automatic method for mapping, based only on images open-source software. As case studies, selected three events recently occurred Spain Italy. Multispectral acquired by MODIS, Proba-V, Landsat, Sentinel-2 SAR collected Sentinel-1 were used...
We study land subsidence processes and the associated ground fissuring, affecting an active graben filled by thick unconsolidated deposits means of InSAR techniques fieldwork. On 21 September 2012, Ciudad Guzmán (Jalisco, Mexico) was struck fissures about 1.5 km length, causing deformation roads propagation in adjacent buildings. The field survey showed that alignment is coincident with escarpments produced on 19 1985, when a strong earthquake magnitude 8.1 central Mexico. In order to detect...
Abstract. Flood mapping and estimation of the maximum water depth are essential elements for first damage evaluation, civil protection intervention planning detection areas where remediation is needed. In this work, we present discuss a methodology quantifying flood severity over floodplains. The proposed considers multiscale multi-sensor approach using free or low-cost data sensors. We applied method to November 2016 Piedmont (northwestern Italy) flood. mapped flooded at basin scale...
Abstract In November 2016, an extreme rainfall event affected the Ligurian Alps (NW Italy). Consequently, several landslides and debris flows occurred in upper Tanarello stream basin. particular, village of Monesi di Mendatica was severely damaged by two landslide phenomena: activation a rotational landslide, which caused total collapse buildings part main road, reactivation deep-seated planar massive complex widely fractured most village. The latter phenomenon mostly unknown had never been...
Differential Interferometric SAR (DInSAR) time-series techniques can be used to derive surface displacement rates with accuracies of 1 mm/year, by measuring the one-dimensional distance change between a satellite and over time. However, slanted direction measurements complicates interpretation signal, especially in regions that are subject multiple deformation processes. The Simultaneous Integrated Strain Tensor Estimation from Geodetic Satellite Deformation Measurements (SISTEM) algorithm...
The comparative analysis of hyperspectral data from different instruments can provide detailed information on the composition and geology similar environments planets. This study aims to compare acquired PRISMA satellite, used for Earth observation, with those collected by CRISM spectrometer onboard Mars Reconnaissance Orbiter, orbiting Mars, in order analyze geological mineralogical differences between morphologies present two planets interest. comparison these will allow us examine...
We present methods and results from interferometric data processing of a long-lasting survey campaign monitoring the Planpincieux glacier, located on Italian side Mont Blanc, using ground-based synthetic aperture radar (GB-SAR). Monitoring European Alpine glacier during winter, when meteorological conditions are highly variable, presents some difficulties in interpretation. The main issues to tackle unwrapping errors high amplitude dispersion (DA), mainly due velocity dielectric...
On 16 November 2006 a flank collapse affected the unstable eastern slope of South‐East Crater (SEC) Mount Etna. The occurred during one paroxysmal events with sustained strombolian activity that characterized August–December eruption and was triggered by erosion loose, hydrothermally altered material steep south‐east sector SEC from outpour lava. produced debris avalanche involved both lithic juvenile resulted in deposit emplaced on volcano up to 1.2 km away source. total volume estimated be...
Rock glaciers are widespread periglacial landforms in mountain regions like the European Alps. Depending on their ice content, they characterized by slow downslope displacement due to permafrost creep. These usually mapped within inventories, but understand activity is a very difficult task, which frequently accomplished using geomorphological field evidences, direct measurements, or remote sensing approaches. In this work, powerful method analyze rock glaciers’ was developed exploiting...
Abstract Land subsidence severely threatens most of the coastal plains around world where high productive industrial and agricultural activities urban centers are concentrated. Coastal damages infrastructures exacerbates effect sea‐level rise at regional scale. Although it is a well‐known process, there still much more to be improved on monitoring, mapping modeling ground movements, as well understanding controlling mechanisms. The International Geoscience Programme recently approved an...
