Composed of recent Alluvium, Shiwalik hills are made up of rocks such as sandstone, shale and clay that came into existence during the Eocene, Miocene and Pliocene period. The central part that extends from Chamba district in the north to Shimla district in the south is mainly represented by Jatog group of rocks which originated in middle Proterozoic period. In the north eastern portion unclassified Granites borders the central part in between Kullu, eastern Shimla, LahaulSpiti and parts of Kinnaur district.

c) Floods:Floods are another form of natural disaster the State experiences every year. South west Monsoonal rainfall during the months of June to August is the dominant cause for triggering floods when rainfall happens to be in excess i.e. 125% or more than the normal. Fig 2.5 shows the percentage frequency of excessive rainfall and successive years of excessive rainfall during the period from 1951 to 1999. During this period the Chamba district in the north western part of the state had received highest amount of rainfall expressed as percentage of the normal with more numbers of successive years of excessive rainfall. Table 2.11 gives the district wise excessive rainfall years and highest annual rainfall expressed as percentage of normal and Table 2.12 gives successive years of excessive rainfall. Fig 2.6 is the map of flood prone areas as prepared by Dr D.D Sharma of H.P University Shimla. Flash Flood:Flash flood is the most frequent and damaging floods that occur with little or ...
