                     Safety measures to be taken for earthquake are:
                      i.     House built should be earthquake resistant.

                      ii.    When earthquakes strikes, people should move out to open spaces.
                      iii.   If stuck inside the house, one should take shelter under a table or
                             desk.

                      iv.    People  should  move  out  through  emergency  exits  and  avoid
