Landslide in Hilly ...


             Chronology of major landslides in Bangladesh are : 10


              Ser  Year                            Event

               1.   1968  At  Kaptai-Chandraghona  road  where  the  protective  vegetation  is
                         removed, the soil gets exposed to the monsoon rains and eroded rapidly.
                         This resulted in landslides, and the loose soil washed down the slopes and
                         carried by rivers into the kaptai lake. As a result, the reservoir silted up
                         and  the  authorities  confirmed  that  in  its  30  years  existence  it  had  lost
                         about 25% of its volume due to siltration.
               2.   1970  Similar  landslide  event  like  1968  took  place  along  Ghagra-Rangamati
                         road.
               3.   1990  Occurred on May 30, 1990. Affected the link road embankment at Jhagar
                         beel area of Rangamati district.
               4.   1997  A major landslide occurred in July 1997 at Charaipada of Bandarban. The
                         total  area  affected  by  it  was  about  90,000-sq  m.  If  such  a  landslide
                         occurred in Bandarban Town and any other urban or semi-urban centre,

                         the devastation would be tremendous.
               5.   1999  Two  big  landslides  one  in  Bandarban  and  the  other  one  in  Chittagong
                         occurred on 11 and 13 August 1999 respectively claiming the life of 17
                         people.  Out  of  17  fatalities,  10  were  in  Chittagong  and  the  rest  in
                         Bandarban district. Heavy and incessant rainfall at that time was one of
                         the  causes  of  sliding.  This  landslide  affected  Lama  thana  and  the  Aziz
                         Nagar union of Bandarban district. Aziz Nagar is almost an inaccessible
                         rugged hilly terrain.
               6.   2007  The 2007 Chattogram Mudslide occurred in the port city Chattogram in
                         south-eastern  Bangladesh.  On  11  June  2007,  heavy  monsoon  rainfall
                         caused landslides that engulfed slums around the hilly areas of the city.
                         Experts had previously warned the increasing likelihood of landslides due
                         to the failure of Bangladesh government in curbing the illegal hill cutting
                         taking place in Chattogram .
