“…The DEM-derived attributes were obtained by using SAGA GIS (Conrad, 2006) tools, calculating thirteen covariates, namely: i) Aspect (Zevenbergen and Thorne, 1987); ii) Slope steepness (Zevenbergen and Thorne, 1987); iii) Relative Slope position (Kleber, 1997); iv) Plan…”

This study aims at evaluating the performance of the Maximum Entropy method in assessing landslide susceptibility, exploiting topographic and multispectral remote sensing predictors. We selected the catchment of the Giampilieri stream, which is located in the north‐eastern sector of Sicily (southern Italy), as test site. On 1 October 2009, a storm rainfall triggered in this area hundreds of debris flow/avalanche phenomena causing extensive economical damage and loss of life. Within this area a presence‐only‐based statistical method was applied to obtain susceptibility models capable of distinguishing future activation sites of debris flow and debris slide, which where the main source of failure mechanisms for flow or avalanche type propagation. The set of predictors used in this experiment comprised primary and secondary topographic attributes, derived by processing a high resolution digital elevation model, CORINE land cover data and a set of vegetation and mineral indices obtained by processing multispectral ASTER images. All the selected data sources are dated before the disaster. A spatially random partition technique was adopted for validation, generating 50 replicates for each of the two considered movement typologies in order to assess accuracy, precision and reliability of the models. The debris slide and debris flow susceptibility models produced high performances with the first type being the best fit. The evaluation of the probability estimates around the mean value for each mapped pixel shows an inverted relation, with the most robust models corresponding to the debris flows. With respect to the role of each predictor within the modelling phase, debris flows appeared to be primarily controlled by topographic attributes whilst the debris slides were better explained by remotely sensed derived indices, particularly by the occurrence of previous wildfires across the slope. The overall excellent performances of the two models suggest promising perspectives for the application of presence‐only methods and remote sensing derived predictors.

“…Due to its porous structure, the thawing behaviour of frozen tephra likely differs remarkably from surrounding materials. Though gelifluction usually dislocates thawed material above the underlying frozen substrate (French, 2007), delayed thawing of tephra material relative to its surroundings (similar to strongly weathered rock fragments dislocated undisturbed by gelifluction as described by Kleber, 1997) may have resulted in dislocation affecting it as a still frozen block embedded in unfrozen matter.…”

An essentially pure tephra layer on a steep slope in the La Sal Mountains, Utah, U.S.A., is correlated with the 1.65 Ma old Guaje Tephra derived from the Jemez Mountains, New Mexico, U.S.A. The heavy-mineral contents and glass shards in sediments beneath the La Sal tephra layer indicate that tephra constituents are contained in deposits considerably older than the pure layer. This suggests that tephra material may become reworked while retaining its pure character, possibly due to laminar transport or to dislocation in a frozen condition. This raises the need to handle tephrochronological findings with great care.

e clay layers at hilly regions in the study area were very thick. e presence of very thick clay caused several difficulties in terms of environmental management, particularly in reducing georisk due to landslide. However, initial observations proved that areas of active landslides had better vegetation cover. e objective of this study was to find out ecological roles of landslides in livelihood in the Middle Bogowonto Watershed. e ecological roles of landslide were examined through field empirical evidences. Texture, bulk density, permeability, structure, and index plasticity were conducted for analyses of soil physical properties.Stepwise interpretation was made using 1 : 100,000-1 : 25,000 Indonesian topographic maps and remote sensing images of 30 m-<10 m spatial resolution. e results showed that landslides formed three landform zones: residual, erosional, and depositional zones. e area that did not slid, the residual zone, had massive soil structure and very hard consistency. Crops cultivated in this zone did not grow well. In the areas of active landslide, the environmental conditions seemed to be more favorable for living creatures. e landslides resulted in depositional zones with gentle slopes (4°to 15°), higher water availability, and easier soil management. e landslides also acted as the rearrangement process of landforms for better living environment.
