Landslide Killing Himalayas: Collective Study on Causal Factors and Possible Remedies

Soil is naturally available material used for construction all over the world. When this material available in form of natural slope can cause landslide. Purpose of this study is to understand behavior of different causal factor of landslide at Himachal Pradesh and then suggest some remedial measure. To fulfill this, aim five-year data of precipitation for every district is collected from metrological department and analyzed. Data of earthquake activities is also collected. Work done by different author in this area is analyzed thoroughly. It is found that the change in climatic conditions such as increase in precipitation over years, earthquakes and anthropogenic interference has increased the landslide susceptibility of area. Remedial measure suggested as use of landslide susceptibility zonation map future land use pattern, use of advance technology like soil nail and gabion wall and use of numerical modeling to analyze slope stability.

Analyzing Trend of Tropical Cyclone Activity Along Odisha Coast, India

A general perception among scientific community and policy makers of developing countries exists that intensity and frequency of tropical cyclones are increasing over time due to climate change and global warming. In the present study, we have tried to investigate the trend and variability of tropical cyclone landfall along the Odisha coast, India. The data pertaining to landfall of the tropical cyclones were collected from Indian Metrological Department and were further filtered using Gaussian filter. The results were plotted in graphical form. Correlation and linear regressions analyses were carried out. The results highlight that the frequency and intensity of tropical cyclone exhibit a decreasing trend. It can be thus be inferred that growing economic loss and loss of lives are due to growing exposure of unplanned population settlements and business investments to extreme events. Therefore socio-economic landscapes need to be adjusted to the landfall of cyclone than blaming natural forces for the loss of lives and properties. Findings of the present study may help policy makers devising future policies in coastal zones.
