We can distinguish three phases of using the SAR and other EO satellite data in landslide studies: 1. Surface characterisation, ie initial topographic and geomorphological classification, DEMs, photogrammetry (using Spot and Landsat); 2. Measurement of slow to extremely slow slope movements by means of SAR interferometry; 3. Systematic monitoring of temporal-spatial variations in some slide pro...

Natural hazards are among destructive agents that annually take thousands of lives and impose devastating damages in Iran. Spotting such a high risk areas can help reducing the amount of their probable risk. A 1:500000 liquefaction and landslide hazard zonation map developed for the southern shoreline of the Caspian Sea. This geotechnical hazard map divides the study area to 15 hazard classes (...

1. introduction generally, landslide studies include process identification, risk analysis and landslide risk prediction (taleby and ezaddoost, 2012). nowadays, there are different methods for landslide simulation such as statistical, descriptive and process-based approaches. however, most studies in iran are based on statistical and descriptive methods (taleby and ezaddoost, 2012). landslide z...

A new comprehensive areal model of earthquake-induced landslides (CAMEL), developed using fuzzy logic systems, is introduced here. CAMEL provides an integrated framework for modelling all types of earthquake-induced landslides using geographic information systems. CAMEL is designed to facilitate quantitative and qualitative representation of terrain conditions and knowledge about these conditio...

Many parts of the world with young mountain chains, such as the Himalayas, are highly susceptible to landslides. Due to general ruggedness and steep slopes, roads provide the only way of transportation and connectivity in such terrains. Generally, landslide hazards are overlooked during route planning. In this study, in a test area in the Himalayas, various thematic layers, viz. landslide distr...

introduction a landslide or landslip is a geological phenomenon which includes a wide range of ground movement, such as rock falls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments. although the action of gravity is the primary driving force for a landslide to occur, there are other contributing factors affecting the original slope s...

A joint conditional probability model is proposed to represent a measure of a future landslide hazard, and five estimation procedures for the model are presented. The distribution of past landslides was divided into two groups with respect to a fixed time. A training set consisting of the earlier landslides and the geographical information system-based multi-layer spatial data in the study area...
