Preevent and event landslide deformations have been detected and measured for the landslide that occurred on 3 December 2013 on the south-western slope of the Montescaglioso village (Basilicata Region, southern Italy). In this paper, ground displacements have been mapped through an integrated analysis based on a series of high resolution SAR (Synthetic Aperture Radar) images acquired by the Ita...

Abstract Dry-snow slab avalanches release due to crack propagation in a weak snow layer under cohesive slab. Crack speeds can provide insights into the potential size of and inform fracture avalanche models. Despite their importance, slope-scale speed measurements from real are limited. Further, most existing utilize appearance fractures on surface. However, we have no evidence that surface cra...

Orientation (or reorientation) is the first step in navigation, because establishing a spatial frame of reference is essential for a sense of location and heading direction. Recent research on nonhuman animals has revealed that the vertical component of an environment provides an important source of spatial information, in both terrestrial and aquatic settings. Nonetheless, humans show large in...

the expanding phenomenon of dieback is caused by the reaction of trees against the harmful biotic and a biotic factor that lead to dying of shoots and branches of trees from upper crown to lower crown. this phenomenon spreads throughout the leaves and branches and all parts of the plant and may finally lead to the death of the plant. this study aimed to identify species dieback especially carpi...

In North-western Iceland, records of slope processes were increasing during the twentieth century. Few dramatic events during the last decades highlighted the danger due to slope dynamics, leaving local populations in a risk situation that was merely unknown before 1970. The recent snow-avalanche, debris-flow and rock-fall activity underlined that the most frequent processes are not these with ...

in order to assess the outing mkhmlkvh forest park area of 430 hectares located in the northern city of khorramabad, gis technology was used. maps of the slope, direction and altitude in the software and arcview3.2 arcgis9.2 were prepared. then combine them with a map of the earth was formed. rvyhmgzary map with the land, soil and vegetation classes, environmental unit maps were prepared. units...

OBJECT To date, there has been no published study in which the focus was on the mechanisms of head injuries associated with snowboarding. The purpose of this study was to identify these mechanisms. METHODS The patient population consisted of 38 consecutive patients with snowboarding-related major head injuries who were treated at two hospitals in Japan, where for years many winter sports inju...

Offset tracking technology is widely studied to evaluate glacier surface displacements. However, few studies have used a cross-platform this end. In study, two heterogeneous data sources, Sentinel-1 and Landsat 8, from January 2019 2021, were estimate the offset, then optimal estimation of 3D deformation rate Himalayan was obtained based on joint model variance component estimation. The results...

this study aimed to determine the prone areas for sugar beet planting with regards to their major effective factors. climatic data of 1998-2009 period were obtained from the local stations of khorasan razavi meteorological bureau. the topographic data including altitude, slope, slope direction, and tin layers were extracted from 1:250000 topographic maps of cartographic organization, iran. the ...
