In the North of Tunisia, Hammam Zriba region represents an important mine activity zone, it is among the most important in the Maghreb . The mine tailings cause the environment degradation, so it had polluted the atmosphere, the soils, the vegetation, the water quality and the ecosystem of the Hammam ouady (Dry River) which is discharged directly in the Miliane River. The Miliane River represen...

Minimization differences on Cellular Automata approach to predict new inundated area of hot mudflow on LUSI mud eruption disaster which occurred in Sidoarjo area is proposed. There are three characteristics of hot mudflow that is unique such as sur face material changes rapidly, surface temperature changes quickly and dike is constructed to avoid spill over. There are penetrations of hot mudflo...

Study of the structural changes in the Popocatepetl volcano in Mexico related to microseismicity by applying the lineament analysis to the Aster (Terra) satellite data. Abstract Mexico is one of the most volcanically active regions in North America. Volcanic activity in central Mex-ico is associated with the subduction of the Cocos and Rivera plates beneath the North American plate. Periods of ...

Land surface temperature (LST) images retrieved from the thermal infrared (TIR) band data of Moderate Resolution Imaging Spectroradiometer (MODIS) have much lower spatial resolution than the MODIS visible and near-infrared (VNIR) band data. The coarse pixel scale of MODIS LST images (1000 m under nadir) have limited their capability in applying to many studies required high spatial resolution i...

Remote sensing has been a key tool for ocean slicks monitoring and new discoveries based on offshore seepage detection. In this context, this contribution has a two-fold objective. Firstly, in order to spectrally characterize hydrocarbons (HCs), we conducted VNIR-SWIR-TIR spectral measurements of petroleum samples yielded from large, off-shore oil fields sited at sedimentary basins of Brazil. S...
