Landslides (LS) represent geomorphological processes that can induce changes over time in the physical, hydrogeological, and mechanical properties of involved materials. For geohazard assessment, variations these might be detected by a wide range non-intrusive techniques, which sometimes confusing due to their significant variation accuracy, suitability, coverage area, logistics, timescale, cost, integration potential; this paper reviews common geophysical methods (GM) categorized as Emitted...

Abstract In Alpine regions changes in seasonal climatic parameters, such as temperature, rainfall, and snow amount have already been observed. Specifically, the South Tyrol area, meteorological observations indicate that temperatures are increasing number of days has generally diminished over time with perennial line now observed at higher elevations. Changes rainfall also more events associated summer season. Natural hazards - mainly debris mud flows, landslides, avalanches, rock falls,...

This paper reviews the classical and some particular factors contributing to earthquake-triggered landslide activity. analysis should help predict more accurately event sizes, both in terms of potential numbers affected area. It also highlights that occurrences, especially those very far from hypocentre/activated fault, cannot be predicted by state-of-the-art methods. Particular attention will paid effects deep focal earthquakes Central Asia other extremely distant activations regions world...

ABSTRACT There is a strong possibility that environmental change (whether climate or land use) will be manifest as changes in the size–frequency distribution of landslides. Here, evidence presented for this from western Kyrgyzstan, Central Asia. Remote sensing and spatial analysis have been applied to map mass movements central part Maily‐Say Valley detect recent landslide activations. The evolution activity over past 50 years has analysed on basis pre‐existing maps new analyses aerial...

Abstract. First analyses of landslide distribution and triggering factors are presented for the region affected by 14 August 2021 earthquake (Mw=7.2) in Nippes Department, Haiti. Landslide mapping was mainly carried out comparing pre- post-event remote imagery (∼0.5–1 m resolution) available on Google Earth Pro® Sentinel-2 (10 satellite images. The first covered about 50 % (for before completion map January 2022), latter were selected to cover entire potentially zone. On basis completed...

From the wide range of methods available to landslide researchers and practitioners for monitoring ground displacements, remote sensing techniques have increased in popularity. Radar interferometry with their ability record movements order millimeters been more frequently applied recent years. Multi-temporal can assist landslides on regional slope scale thereby assessing related hazards risks. Our study focuses Corvara Italian Alps, a complex earthflow spatially varying displacement...

This paper presents an analysis of the integration between interferometric and intensity-offset tracking-based SAR remote sensing for landslide hazard mitigation in Italian Alps. Despite advantages Synthetic Aperture Radar Interferometry (InSAR) methods quantifying deformation, some limitations remain. The temporal decorrelation, 1-D Line Of Sight (LOS) observation restriction, high velocity rate multi-directional movement properties make it difficult to monitor accurately complex landslides...

The Copernicus Sentinel-1 mission provides synthetic aperture radar (SAR) acquisitions over large areas with high temporal and spatial resolution. This new generation of satellites providing open-data products has enhanced the capabilities for continuously studying Earth surface changes. Over past two decades, several studies have demonstrated potential differential interferometry (DInSAR) detecting quantifying land deformation. DInSAR limitations challenges are linked to SAR properties...

Central Asian mountain regions are prone to multiple types of natural hazards, often causing damage due the impact mass movements. In spring 2017, Kyrgyzstan suffered significant losses from a massive landslide activation event, during which also two largest deep-seated movements former mining area Mailuu-Suu—the Koytash and Tektonik landslides—were reactivated. This study consists use optical radar satellite data highlight deformation zones identify displacements prior collapse more...

Abstract. In the paper we analyse a multi-date landslide inventory prepared for mountainous area affected by several types with different degrees of activity, attempt to quantify uncertainties associated mapping, measure evolution morphological indicators and estimate activity temporal occurrence. The inventory, covering period 1956–2010, is middle section Ubaye valley (southern French Alps) based on analysis multi-source documents (geomorphological maps, historical reports events, field...

Abstract. Terrestrial and airborne 3D imaging sensors are well-suited data acquisition systems for the area-wide monitoring of landslide activity. State-of-the-art surveying techniques, such as terrestrial laser scanning (TLS) photogrammetry based on unmanned aerial vehicle (UAV) imagery or acquisitions have advantages limitations associated with their individual measurement principles. In this study we present an integration approach point clouds derived from these aiming at improving...

Abstract Glacial lake outburst floods (GLOFs) are sudden, and often hazardous, occurring upon the failure of a glacial dam or moraine. A GLOF occurred at Sulzenau Lake (Tyrol, Austria) in August 2017 due to partial moraine failure, damaging nearby infrastructure. Due ongoing retreat Glacier, areal extent, depth, water volume, shoreline configuration fluctuate over both short‐ long‐term periods. Here, we used remote sensing data create detailed geomorphological overview valley, analyse lake's...

<p>Landslides are recurrent in most mountainous areas of the world where they frequently have catastrophic consequences. Around Fergana Basin and Maily-Say Valley (Kyrgyzstan), landslides often reactivated due to intense rainfalls, especially during spring, as a consequence high seismicity characterizing region. In spring 2017, Kyrgyzstan suffered massive activation event which caused 160 emergency situations, including reactivation Koytash, one largest deep-seated mass...

This study presents the results of a landslide susceptibility analysis applied to Vrancea-Buzău seismogenic region in Carpathian Mountains, Romania. The target area is affected by large diversity processes. Slopes are made-up various types rocks, climatic conditions can be classified as wet, and seismically active one. All this contributes observed high hazard. paper analyses spatial component hazard affecting area, regional susceptibility. First, an existing inventory was completed cover...
