Landslides are one of the most devastating disasters among all natural hazards in Brazil, with nearly 3,355 fatalities between 1988 and 2013. Apart from the loss of lives, they also cause substantial economic losses. As an example, the mass movements that occurred in 2011 in Rio de Janeiro resulted in US$ 2.8 billion in damage. Thus, in order to mitigate these hazards, it is essential to map th...

The purpose of mass wasting susceptibility assessment using a Geographic Information System is to assign, in a regional scale, places were these events are more probable to take place. Fernandes & Amaral (1996) consider that the main purpose of mass wasting susceptibility maps is to provide information about the probability of mass wasting occurrence, dividing the whole area in certain landscap...

introduction landslide is a geologic process that occurs over a wide variety of spatial and temporal scales in many mountainous landscapes. landslides have a correspondingly wide range of effects that depends strongly on their spatial pattern of occurrence and frequency and magnitude of movement. mass movements can be the dominant source of erosion responsible for the long-term geomorphic evolu...

Landslides as major natural geological hazards often result in significant harm to people and property. Between 20 and 31 August, 2002, Typhoon Rusa hit the Gangneung area as a storm associated with heavy rainfall. The maximum daily rainfall amounted to 609 mm, with 80 mm per hour. The consequence was the death of 266 people. Damage to property amounted to an approximate value of US$ 8 billion....

The often-used success rate (SR) in measuring cell-based landslide model efficiency is based on the ratio of successfully predicted unstable cells over total actual landslide sites without considering the performance in predicting stable cells. We proposed a modified SR (MSR), in which we include the performance of stable cell prediction. The 5 goal and virtue of MSR is to avoid over-prediction...

every year, a considerable portion of the national budget specifies to reconstruct the properties which have been destroyed during natural disasters in iran. recognition of vulnerable sites to natural disasters can reduce the probable damages. the most important point in designing railway tracks is to join stations in the least possible time. so, the railway track is meant to cross lots of vall...

a r t i c l e i n f o Multi-temporal ALOS/PALSAR images are used to automatically investigate landslide activity over an area of ~ 200 km by ~ 350 km in northern California and southern Oregon. Interferometric synthetic aperture radar (InSAR) deformation images, InSAR coherence maps, SAR backscattering intensity images, and a DEM gradient map are combined to detect active landslides by setting ...
